The Mystery behind the 18 Giant Skeletons found in the USA

18 Strange Skeletons Found in Wisconsin Nine-foot Skeletons with Huge Heads and Strange Facial Features Shocked Scientists When They Were Uncovered 107 Year Ago Scientists are remaining stubbornly silent about a lost race of giants found in burial mounds near Lake Delavan, Wisconsin, in May 1912.

The dig site at Lake Delavan was overseen by Beloit College and it included more than 200 effigy mounds that proved to be classic examples of 8th century Woodland Culture. But the enormous size of the skeletons and elongated skulls found in May 1912 did not fit very neatly into anyone’s concept of a textbook standard.

They were enormous. These were not average human beings.

Strange Skulls

First reported in the 4 May 1912 issue of the New York Times, the 18 skeletons found by the Peterson brothers on Lake Lawn Farm in southwest Wisconsin exhibited several strange and freakish features.

Their heights ranged between seven and nine feet and their skulls “presumably those of men, are much larger than the heads of any race which inhabit America to-day.”

Above the eye sockets, “the head slopes straight back and the nasal bones protrude far above the cheekbones. The jawbones are long and pointed, bearing a minute resemblance to the head of the monkey. The teeth in the front of the jaw are regular molars.”

The mystery of The Wisconsin Giants

Was this some sort of prank, a hoax played by local farm boys or a demented taxidermist for fun and the attention of the press? The answer is no.

The Lake Delavan find of May 1912 was only one of the dozens and dozens of similar finds that were reported in local newspapers from 1851 forward to the present day. It was not even the first set of giant skeletons found in Wisconsin.

On 10 August 1891, the New York Times reported that scientists from the Smithsonian Institution had discovered several large “pyramidal monuments” on Lake Mills, near Madison, Wisconsin. “Madison was in ancient days the center of a teeming population numbering not less than 200,000,” the Times said. The excavators found an elaborate system of defensive works which they named Fort Aztalan.

“The celebrated mounds of Ohio and Indiana can bear no comparison, either in size, design or the skill displayed in their construction with these gigantic and mysterious monuments of the earth — erected we know not by whom, and for what purpose we can only conjecture,” said the Times.

On 20 December 1897, the Times followed up with a report on three large burial mounds that had been discovered in Maple Creek, Wisconsin. One had recently been opened.

“In it was found the skeleton of a man of gigantic size. The bones measured from head to foot over nine feet and were in a fair state of preservation. The skull was as large as a half bushel measure. Some finely tempered rods of copper and other relics were lying near the bones.”

Giant skulls and skeletons of a race of “Goliaths” have been found on a very regular basis throughout the Midwestern states for more than 100 years. Giants have been found in Minnesota, Iowa, Illinois, Ohio, Kentucky, and New York, and their burial sites are similar to the well-known mounds of the Mound Builder people.

The spectrum of Mound builder history spans a period of more than 5,000 years (from 3400 BCE to the 16th CE), a period greater than the history of Ancient Egypt and all of its dynasties.

There is a “prevailing scholarly consensus” that we have an adequate historical understanding of the peoples who lived in North America during this period. However, the long record of anomalous finds like those at Lake Delavan suggests otherwise.

The Great Smithsonian Cover-Up

Has there been a giant cover-up? Why aren’t there public displays of gigantic Native American skeletons at natural history museums?

The skeletons of some Mound Builders are certainly on display. There is a wonderful exhibit, for example, at the Aztalan State Park where one may see the skeleton of a “Princess of Aztalan” in the museum.

But the skeletons placed on display are normal-sized, and according to some sources, the skeletons of giants have been covered up. Specifically, the Smithsonian Institution has been accused of making a deliberate effort to hide the “telling of the bones” and to keep the giant skeletons locked away.

In the words of Vine Deloria, a Native American author, and professor of law:

“Modern day archaeology and anthropology have nearly sealed the door on our imaginations, broadly interpreting the North American past as devoid of anything unusual in the way of great cultures characterized by a people of unusual demeanor. The great interloper of ancient burial grounds, the nineteenth century Smithsonian Institution, created a one-way portal, through which uncounted bones have been spirited. This door and the contents of its vault are virtually sealed off to anyone, but government officials. Among these bones may lay answers not even sought by these officials concerning the deep past.”

Maize, not metal, the key to native settlements’ history in New York

The Recent Cornell University research offers a more detailed historical timeline for the occupation of Native American sites in upstate New York, based on radiocarbon dating of organic materials and statistical modeling.

Reports from the study of a dozen sites in Mohawk Valley were recently published by Sturt Manning in the online journal PLoS ONE, the professor of classical archeology; and John Hart, curator in the research and collections division of the New York State Museum in Albany.

The findings, Manning said, are helping to refine our understanding of the social, political, and economic history of the Mohawk Valley region at the time of early European intervention.

The Iroquoian Study

The work is part of the Dating Iroquoia Project, involving researchers from Cornell, the University of Georgia, and the New York State Museum, and supported by the National Science Foundation.

The new paper continues and expands upon research on four Iroquoian ( Wendat) sites in southern Ontario, published by the project team in 2018. Using similar radiocarbon dating and statistical analysis methods, the 2018 findings also impacted the timelines of Iroquoian history and European contact.

“The Mohawk case was chosen because it is an iconic series of indigenous sites and was subject to one of the first big dating efforts in the 1990s,” said Manning. “We have now examined a southern Iroquois ( Haudenosaunee) case as well as a northern Iroquois (Wendat) case, and we again find that the previous dating scheme is flawed and needs revision.”

The Mohawk and Hudson river valleys were key inland routes for Europeans entering the region from the coast in the 16th and early 17th centuries. Colonization of the new world enriched Europe (Manning has described this period as “the beginning of the globalized world”) but brought disease and genocide to indigenous peoples, and their history during this time is often viewed in terms of trade and migration.

Iroquoian Trade Goods

The standard timeline created for historical narratives of indigenous settlement, Manning noted, has largely been based on the presence or absence of types of European trade goods – e.g., metal items or glass beads. Belying this Eurocentric colonial lens, trade practices differed from one native community to another, and not all of them accepted contact with, or goods from, European settlers.

To clarify the origins of metal goods found in the upstate New York settlements, the team used portable X-ray fluorescence (pXRF) analysis to determine whether copper artifacts were of native or European origin. They then also re-assessed the dates of the sites using radiocarbon dating coupled with Bayesian statistical analysis.

Bayesian analysis, Manning explained, is “a statistical method that integrates prior knowledge in order to better define the probability parameters around a question or unknown. In this case, archaeological and ethnohistorical information was combined with data from a large set of radiocarbon dates in order to estimate occupation dates for a set of Mohawk villages across the 13th to early 17th centuries.”

The focus was on the period from the late 15th to the early 17th century, he said, or “the long 16th century of change in the northeast”. The results “add to a growing appreciation of the interregional variations in the circulation and adoption patterns of European goods in northeastern North America in the 16th to earlier 17th centuries,” Manning said.

Iroquoian History Reevaluated

In previous indigenous site studies, where artifacts indicated trade interactions, researchers might assume “that trade goods were equally available, and wanted, all over the region,” and that different indigenous groups shared common trade practices, he said. Direct radiocarbon dating of organic matter, such as maize kernels, tests those assumptions and removes the colonial lens, allowing an independent timeframe for historical narratives, Manning said.

At several major Iroquois sites lacking close European connections, independent radiocarbon studies indicate substantially different date ranges from the previous estimates based on trade goods.

“The re-dating of a number of Iroquoian sites also raises questions about the social, political and economic history of indigenous communities from the 14th to the 17th centuries,” Manning said. “For example … a shift to larger and fortified communities, and evidence of increased conflict,” was previously thought to have occurred around the mid-15th century.

But the radiocarbon findings from some larger sites in Ontario and their cultivated maize fields ¬- 2,000 acres or more in some instances — date the sites from the mid-16th to the start of the 17th century, he said. “However, as this New York state study shows, other areas had their own and differing trajectories. Thus with direct dating we start to see real, lived, histories of communities, and not some imposed generic assessment,” Manning said.

“The emerging new and independent timeframe for northeast North America will now form the basis of a wider indigenous history,” Manning stated, “free from a Eurocentric bias, with several past assumptions open for an overdue rethink.” Cornell University has dedicated television and audio studios available for media interviews supporting full HD, ISDN, and web-based platforms.

200 million-year-old shoe print found on a lump of coal

In the past, there have been countless mysterious discoveries that point to the fact that modern humans lived on Earth much earlier than scholars say. Such unexplained observations referred to by many authors as ‘ ooparts — or out of place artifacts’, these enigmatic findings push the boundaries set forth by mainstream scholars, challenging everything we know about modern humans and life on Earth.

A hundred years ago, a Nevada Mining Company employee named Albert E. Knapp made the enigmatic — and somewhat controversial — discovery. To be precise in January 1917.  In an article at creationism.org, we find a letter written by Mr. Knapp—the discoverer—dating back to January 15, 1917.

“I was intrigued by the fossil, which laid on the stone side among some loose rocks, as I descended the hill my attention was attracted by the fossil. I took it and placed it in my pocket for further analysis and it came to the conclusion that it is a layer from the heel of a shoe which had been pulled from the balance of the heel by suction; the rock was in a plastic state at that time. It was found in LIMESTONE OF THE TRIASSIC PERIOD, a belt of which runs through that section of the hills.”

There are however several websites that wrongly concluded that the ‘ 200 million-year-old fossilized shoeprint ‘ was found in Triassic rock near Fisher Canyon, Pershing County, Nevada by John Reid in 1922.

The enigmatic object caught the attention of several researchers who were looking forward to analyzing it. The object also caught the eyes of the media as we find two reports about the discovery in a March 19, 1922 story in the New York Times: “It would fit nicely a boy of ten or twelve years. The edges are as smooth as if freshly cut. The surprising part of it is what seems to be a double line of stitches, one near the outside edge of the sole and the other about a third of an inch inside the first. The ‘leather’ is thicker inside the inner welting and appears to be slightly bevelled, so that at the margin, half an inch wide, which runs outside, the sole is something like an eighth of an inch thick.

The symmetry is maintained perfectly throughout. The perfect lines pursued by the welting, and the appearance of hundreds of minute holes through which the sole was sewed to the shoe are the things which make the object such an extraordinary freak in the eyes of the scientists who examined it.

And an October 8, 1922 article by W. H. Ballou in the American Weekly section of the New York Sunday American titled: “Mystery of the Petrified Shoe Sole”:

“…Some time ago, while he was prospecting for fossils in Nevada, John T. Reid, a distinguished mining engineer, and geologist stopped suddenly and looked down in utter bewilderment and amazement at a rock near his feet. For there, a part of the rock itself was what seemed to be a human footprint! Closer inspection showed that it was not a mark of a naked foot, but was, apparently, a shoe sole which had been turned into stone.

The forepart was missing. But there was the outline of at least two-thirds of it, and around this outline ran a well-defined sewn thread which had, it appeared, attached the welt to the sole. Further on was another line of sewing, and in the center, where the foot would have rested had the object really been a shoe sole, there was an indentation, exactly such as would have been made by the bone of the heel rubbing upon and wearing down the material of which the sole had been made. Thus was found a fossil which is the foremost mystery of science today. For the rock in which it was found is at least 5 million years old…”

However, as noted by paleo.cc, the article that appeared in New York Sunday American mistakenly credits Reid instead of Knapp as the person who discovered it, but it offers misleading details about the age to the artifact.

Several authors concluded upon closer inspection that the rock shows “a layer from the heel of a shoe which had been pulled up from the balance of the heel by suction, the rock being in a plastic state at the time.”

Furthermore, it is noted that the alleged shoe print was in a marvelous state of preservation—as the edges of the heel were smooth and rounded off as if cut and its right side appeared more worn than the left—an indicative sign that it had been worn on the right foot.

However, many authors and websites—who disagree with mainstream history mostly—argue that what Knapp found really amazing was that the rock in which the heel mark was made, was a Triassic rock—believed to be at least 220 million years old—which runs in a belt through the canyon hills where the enigmatic shoeprint was discovered.

But author Glen J. Kuban notes that there are several issues with the shoeprint interpretation.

The Kuban notes that from the only photographs from the artifact, we can deduce that it seems to be a broken ironstone concretion, one that may have suffered from erosion. Interestingly, such concretions tend to display ovoid shapes and concentric banding like the one discovered in the alleged 200 million-year-old shoe print.

As noted by essayfarm.com, Concretions are hard to compact accumulations of mineral matter and are found inside sedimentary rocks. Often concretions are mistaken for bones, fossils, meteorites and other odd objects. They can be so small that it requires a magnifying glass to be visible or as large as 10 feet in diameter and weigh hundreds of pounds.  Concretions can also have somewhat of regular shapes such as boxes, blocks, flat disks, pipes, cannonballs and have even been known to resemble parts of a human body such as a foot or ribs.

As noted in the book God-Or Gorilla by McCann, Alfred Watterson, 1879-1931, the Rockefeller Institute conducted microscopic photography of the print, which showed that the object in question contained the presence of two rows of stitching, about 1/3″ apart, with the appearance of hundreds of minute holes through which the soul was sewed to the shoe. Regrettably, no microscopy images were published to back the claims.

“The edges are rounded off smoothly as if it were freshly cut leather from an expert cobbler. The stone to which it is attached is about the size of a brick. The heel and part of the sole appear, the toe-end being missing.”

Creationsim.org states that the above-mentioned microphotographs showed very clearly that it bore a minute resemblance to a well-made piece of leather, stitched by hand, and at one time worn by a human foot.

The photographs showed the stitches very plainly; at one place it was double-stitched, and the twist of the thread could be clearly seen. The thread is smaller than any used by shoemakers of today. Minute crystals of sulphide of mercury are to be noticed throughout the spaces of this fossil shoe-sole, these minerals having been deposited in the long ago by waters which carried them in solution.

Regrettably, the present location of the artifact is unknown, so further studies cannot be conducted.

Petrified Opal Tree Trunk Situated In Arizona Its About 225 Million Years Old

What happened to the wood that made it that way in the beautiful petrified trees in the forests of Arizona? They believe that petrified wood is so old that in the prehistoric period it has emerged. But do you know how petrified wood was made? This guide will show you how. What is petrified wood and how is it formed?

Fossil wood is considered to have grown when the material of the plant is buried by sediment. When the wood is buried deep in the muck, it is protected from decay caused by exposure to oxygen and organisms.

Because the wood is stored in deep water, the minerals in the groundwater flow through the sediment, replacing the original plant material such as silica, calcite, and pyrite.

Even very expensive minerals can infiltrate wood-like opal. The result is a fossil made from the original woody material, which often shows preserved details of tree bark, wood, and cellular structures.

This is probably the most popular petrified park in the world. The Petrified Forest National Park near Holbrook in northeastern Arizona has established millions of years ago. About 225 million years ago, this was simply a lowland with a tropical climate with a dense forest.

Rivers made by tropical rainstorms washed mud and other sediments. This was where you would find giant coniferous trees 9 feet in diameter and towering 200 feet lived and died.

Fallen trees and broken branches from these trees were buried by rich river sediments. Meanwhile, volcanoes nearby erupted numerous times and the ash and silica from these eruptions buried the area.

Eruptions caused large dense clouds of ash that buried the area and this quick cover prevented anything from escaping and of course, nothing can also move in, even oxygen and insects. In time, the soluble ash was dissolved by groundwater through the sediments. The dissolved ash became the source of silica that replaced the plant debris.

This silication process creates petrified wood. Aside from silica, trace amounts of iron, manganese and other minerals also penetrated the wood and this gave petrified wood a variety of colors. This is how the lovely Chinle Formation was made.

So how was this area discovered? Millions of years after the Chinle Formation were created, the entire area was dug and the rocks found on top of Chinle have eroded away.

What was discovered was wood here was much harder and resistant to weathering compared to the mudrocks and ash deposits in Chinle. Wood that was taken from the ground surface as nearby mudrocks and ash layers washed away.

The park covers 146 square miles.   It’s dry and often windy, but the elevation of 5400 feet means that it’s not as hot as desert areas at lower altitudes, and it’s mostly covered in the grass rather than cacti and other desert plants.

Of course, the big attraction here is the petrified trees, which grew here about 225 million years ago when this part of Arizona was at a much lower elevation near the shores of a large sea to the west.

As well as the trees, many fossilized animals such as clams, freshwater snails, giant amphibians, crocodile-like reptiles, and early dinosaurs have been found here.

The silica in the logs crystallized into quartz, but often iron oxide and other minerals were mixed in, producing extraordinarily beautiful kaleidoscopic patterns and colors.

The petrified trees are often so attractive that a whole industry grew up around hauling them out from where they lay and cutting them up to make decorative furniture, wall displays, bookends, and other items. Theft from the park has always been a problem, and it’s estimated that around 12 tons of fossilized wood are stolen each year.

The Nampa Figurine: 2-million-year-old Relic or Just a Hoax?

Nampa Statue or Nampa Figure is the figure discovered in Idaho in 1889 on the ground layers, that is believed two million years old.

This statue has given rise to theories on the origins of mankind. Some people say it’s just fake but this high class small human figure is a very interesting thing, which might have also the more natural explanation.

The theory of the two million years old human civilization may, of course, be possible, and here we must say that one statue would not make civilization.

The figure is found 300 feet deep, and it is 91 meters in the metric system. So the person or persons who dig that statue in the ground must spend very much time on that operation.

There is one special detail of that figure, and it seems to wear European clothes. Also, the figure seems hanged, but this might be only the imagination. There is claimed to have evil forces in this figure, what is the really mysterious artifact.

But there is one very interesting explanation for this creature. This explanation is connected with the syndrome called “Savant autism”. This syndrome is causing the situation, that some people would have limits in the many skills, but in one special skill, this kind of person would be the best in the world. Some of those persons who are “savant autistic” are making extremely perfect things by using mud.

And those persons actually make those statues automatically. If that statue is made by some savant autistic, the family of that person would like to hide that thing, because those persons are sometimes faced with the violence, because they are different than others. That’s why this statue could be buried to the ground because the community wanted to hide the syndrome.

There are also many other theories about those strange creatures.  Of course, extraterrestrials and UFO:s might be the natural explanation. Sometimes I have thought that could behind those strange creatures be Cro-Magnon man, what was able to make the statue, but making the statue doesn’t mean, that they could write.

Or sometimes some persons have thought that maybe some slave has taken the special LwaLwa statue from Africa without permissions, and afraid the consequences.

The Nampa figure is quite small, and maybe it was specially made for some purpose.  Maybe this statue is bought by some slave, who would dig it in the ground because white men punished non-christian slaves.

And that statue was the religious symbol. Some stories are told that this statue was carried by escaped slaves sometimes on the 18th. or 19th. century. But why this slave would use all that time for digging this statue so deep.

The process would take a very long time, and if this person would get help from other people, should there be some reason for that trouble.

Then this person digs that statue in the ground because that person didn’t want that it would get into the hands of the slave keepers. But those are only theories.

Inside the excavation of a South Dakota sinkhole that swallowed more than 60 mammoths

When I learned of this and ongoing mammoth fossil excavations, I thought that this was fake But when I was inside the building and I saw that real work was taking place, I was delighted to see the history of the building opened in front of your eyes.

The Mammoth Site is a ‘ successful paleontological mining site with the highest concentration of mammal remains worldwide! ‘ According to the website. “The mammoth count is currently 61, with 58 Colombian mammoths and 3 Woolly mammoths found.

Just 140,000 years later, in 1974, when a worker preparing the field for a housing project hit a tusk with the blade of his machine. 

The Mammoth Site has been an active dig ever since, one of the few places in the U.S. where you can follow a fossil’s path from the ground to the preparation lab to the museum floor, all within the same building.

Excavating the Ice Age

Turning into the parking lot, I’m greeted by a life-size reconstruction of one of the site’s namesakes, a Columbian mammoth, raising its trunk above the museum’s welcome sign. The town of Hot Springs has fully embraced the local extinct wildlife.

The restaurant next to the museum is named Woolly’s, in honor of the smaller species of mammoth found next door, and there are a surprisingly large number of visitors on the site’s morning tours for a day in late September.

As I enter the room that houses the dig itself, I’m struck by the height of the excavation. It takes a pretty big hole in the ground to trap upwards of 60 mammoths (mostly the larger Columbian species, though they’ve found a couple of woolly mammoths, too), but hearing about it and seeing it in person are two different things.

The way the bones have been excavated has left dramatic sheer walls and flat terraces in the yellowish-tan earth, on which light brown mammoth skulls sporting huge tusks sit like statues on pedestals. The bones are jumbled together and piled high—nothing like that perfectly articulated skeleton in Jurassic Park.

Descending the stairs from the main wooden walkway that encircles the active parts of the dig to stand on a fenced-in platform on the level of one of the deepest floors, I’m keenly aware that there are likely many more bones of Ice Age animals beneath my feet. Along with the famous mammoths, many other species have been found here, including llamas, camels, and the giant short-faced bear (Arctodus simus).

The site’s geologists have figured out that the sinkhole was originally about 65 feet deep. The dedicated crew of paleontologists, interns, and volunteers working at the site have only excavated about 20 feet of that. And, unlike the Jurassic Park paleontologists, they’re not doing it with just paintbrushes and bare hands.

A prehistoric puzzle

On the day of my visit, a group of adult volunteers sits in the less-excavated half of the bonebed, gently tapping away with hammers and small chisels, scraping with trowels, and scooping the loose sediment into buckets.

One of the least glamorous parts of a thorough excavation is screen-washing, where bucket after bucket of dirt is rinsed through a screen until only small bits of rock, bone, and teeth are left behind. What remains is then picked through for tiny fossils of small mammals—rodents and rabbits—that also met their end in the sinkhole.

Some of this picking happens downstairs, in the Mammoth Site’s fossil preparation lab. A short elevator ride down to the museum’s lower floor reveals the part of paleontology most people don’t think about when they see a beautifully complete mounted skeleton in a museum.

After leaving the elevator, I’m greeted by a wall of windows. Here, visitors can peer into the lab as bits of bone are painstakingly cleaned and glued back together, like putting together a puzzle where half of the pieces are broken or missing.

A wall-mounted TV plays a video of the site’s molding and casting process. Silicone rubber is used to make an exact mold of a fossil. That mold can then be used to create replicas (called casts) of the bone, which are often what ends up mounted in museums. Fossils are fragile and irreplaceable, so it’s safer to work with the casts.

The people who work in these spaces are the unsung heroes of paleontology, painstakingly bringing ancient bones back to life. While a lot of museums are starting to pull back the curtain on what it takes to prepare a fossil when it comes in from the field by building these kinds of “fishbowl” lab spaces, the Mammoth Site is a rare destination because the fossils are being both excavated and pieced back together inside the same building.

Heading back upstairs, I see the work of the site’s preparators in the museum’s more traditional gallery space, where mounted mammoths and replicas of huts made of casts of mammoth bones and faux-fur await.

Half of this space is dedicated to ancient life in the Black Hills and surrounding areas, but the other half is all about fossil elephants and their relatives. Bits of mummified tissue from mammoths found in the Siberian permafrost fill the cases on one wall. Mounted skeletons include a Channel Islands pygmy mammoth, a dwarf descendent of mainland Columbian mammoths.

The Mammoth Site is a local treasure of international scientific importance, and I leave with a certain amount of envy that the residents of Hot Springs get to live with these fossil riches so close at hand. But I’m also reminded that the traces of prehistoric life are everywhere—even if they’re usually less dramatic than a sinkhole full of mammoths.

Humans were in America 100,000 years earlier than we thought, study claims

The remnants of a mastodon found in a routine freeway excavation in San Diego shows there was human activity in North America 130,000 years ago — or about 115,000 years earlier than previously thought.

The fossils of the ancient mammal were revealed more than 20 years ago by paleontologists with the San Diego Natural History Museum. But it wasn’t until now that scientists were able to accurately date the findings, and possibly rewrite the history of the New World as we know it.

“This is a whole new ball game,” Steve Holen, co-director of the Center for American Paleolithic Research and the paper’s lead author, told CNN. The discovery changes the understanding of when humans reached North America.

The study, to be published this week in the science journal Nature, said the numerous limb bones fragments of a young male mastodon found at the site show spiral fractures, indicating they were broken while fresh.

Hammerstones and stone anvils were also found at the site, showing that humans had the manual skill and knowledge to use stone tools to extract the animal’s marrow and possibly to use its bones to make tools.

The discovery took place in 1992 by museum paleontologists, who were doing routine work at a freeway expansion in San Diego County. The site was named Cerutti Mastodon site, in honor of Richard Cerutti, who made the discovery and led the excavation.

Museum paleontologist Tom Deméré, who was involved in the excavation and has also been part of this study, said the project took five months and covered almost 600 square feet. He described the decades-long project as an “incredible odyssey.”

“We early on realized that this is a special site,” said Deméré, adding later the group was “salvaging fossils as they were being found.”

Five large stones, which were used to break the bones and teeth of the mastodon, were found alongside the animal’s remains, according to the study. The site also contained fossils of other extinct animals, including dire wolf, horse, camel, mammoth and ground sloth.

Scientists specialized in various fields, from archaeology to the environment, have done research at the Cerutti site since its discovery.

Advanced radiometric dating technology allowed scientists to determine the mastodon bones belong to the Late Pleistocene period, or 130,000 years old, with a margin of error of plus or minus 9,400 years.

“The bones and several teeth show clear signs of having been deliberately broken by humans with manual dexterity and experiential knowledge,” Holen said in a press release.

Experts agreed that the earliest records of human ancestors in North America is about 15,000 years old, but the discovery of the Cerutti site “shows that human ancestors were in the New World ten times that length of time,” said paleontologist Lawrence Vescera.

“This site really nails it because the evidence is really clear.”

The 11 scientists involved in the study told CNN it’s too early to tell the impact of the new findings. For now, they want the general audience to see it and understand it, and for their peers to study it — and even challenge it.

The archaeological treasures found at the Cerutti site will be on display at the San Diego museum. And a partnership with the University of Michigan will allow for even more people to see 3-D models of some of the specimens at their Online Repository of Fossils.

Huge 300-Million-Year-Old Shark Skull Found Deep Inside An Underground Kentucky Cave

In the walls of a Kentucky cave, a fossilized shark’s head was found around 300 million years ago.

Scientists suggest that it was part of a striatus of Saivodus, which existed during the Late Mississippian geological age between 340 million and 330 million years ago.

It shows the skull, the lower jaws, cartilage and several teeth of the creature. The team believes that the size of the animal is similar to our modern Great White Shark.

The ancient shark head was uncovered in Mammoth Cave National Park, located in Kentucky, which is Earth’s oldest known cave system, the Louisville Courier-Journal reported.

It was first spotted in a treasure trove of fossils by Mammoth Cave specialists Rick Olson and Rick Toomey, who sent images of their findings to Vincent Santucci, the senior paleontologist for the National Park Service in Washington, D.C., for help with identifying the fossils.

But it was paleontologist John-Paul Hodnett who made the exciting discovery.

‘One set of photos showed a number of shark teeth associated with large sections of fossilized cartilage, suggesting there might be a shark skeleton preserved in the cave,’ he told the Journal.

The head was well-preserved in the cave and the team was able to make out the shark’s skull, lower jaw, cartilage, and numerous teeth. Based on these features, Hodnett believes the shark was about the size of a modern-day great white.

The Mammoth Cave National Park holds a trove of ancient fossil – more than 100 shark species have been discovered so far.

‘We’ve just scratched the surface,’ Hodnett said. ‘But already it’s showing that Mammoth Cave has a rich fossil shark record.’

A discovery such as this is very rare, as cartilage does not usually survive fossilization. However, shark teeth are commonly found, as they are made of bone and enamel, making them easy to preserve.

Hodnett said teeth and dorsal fins of other shark species are also exposed in the cave ceiling and walls.

‘We’ve just scratched the surface,’ Hodnett said. ‘But already it’s showing that Mammoth Cave has a rich fossil shark record.’  

A separate exudation found teeth that they believed belonged to the largest prehistoric shark that lived over 2.5 million years ago.  The discovery was made by divers in an inland sinkhole in central Mexico supporting anthropologists’ theories that the city of Maderia was once under the sea.

Fifteen dental fossils were found in total with thirteen of them believed to belong to three different species of shark, including a megalodon that existed over 2.5 million years ago.

According to the researchers involved, an initial exam of the thirteen shark dental fossils and their size and shape revealed that they might have belonged to the prehistoric and extinct species of megalodon shark (Carcharocles megalodon), the mackerel shark (Isurus oxyrinchus) and the saw shark, the last two of which are not extinct.

The fossils belong to the period of Pleiocene, the epoch in the geologic timescale that extended from 5 million to 2.5 million years ago, and the Miocene, an earlier geological epoch which extended between 23 and 5 million years ago.

Reports state the Xoc cenote is the largest in the city of Merida with a diameter of 2,034 feet and 91 feet deep.
