Hundreds of Well Preserved Prehistoric Animals have been found in an Ancient Volcanic Ashbed in Nebraska

The watering holes attracted prehistoric animals among Nebraska’s tall grasslands. From horses to camels and rhinoceroses, with wild dogs looming nearby, animals roamed the savanna-like region.

Then, one day, it all changed. Hundreds of miles away, a volcano in southeast Idaho erupted. Within days, up to two feet of ash covered parts of present-day Nebraska.

Some of the animals died immediately, consumed with ash and other debris. Most of the animals lived for several more days, their lungs ingesting ash as they searched the ground for food. Within a few weeks, northeast Nebraska was barren of animals, except for a few survivors.

More than 12 million years later, a fossil was found in Antelope County, near the small town of Royal.

The skull of a baby rhino was discovered by a Nebraska paleontologist and his wife while exploring the area. The fossil was exposed to erosion. Soon after, exploration started in the area.

As more discoveries were made, the site grew into a tourist attraction. Today, people visit Ashfall Fossil Beds State Historical Park to check out hundreds of fossils from 12 species of animals, including five types of horses, three species of camels, as well as a saber-toothed deer. The infamous saber-toothed cat remains a dream discovery.

Visitors view fossils inside the Hubbard Rhino Barn, a 17,500-square-foot facility that protects the fossils while allowing visitors to roam on a boardwalk. Kiosks provide information on fossils located in specific areas.

As you tour the barn, if a summer intern or paleontologist is nearby, they are open to discussing their work, as well as answering questions. During our visit, we learned that an intern had discovered a fossilized dog paw print.

Outside the barn, visitors can read facts about the area, including that mammoths migrated to North America about 1.5 million years ago.

A yellow flag in an area a short distance from the main walk to the barn indicates the discovery site of the rhino skull. Red flags showcase spots where additional fossils were discovered.

Visitor activities and views at Ashfall Fossil Beds

In addition to the Hubbard Barn, Ashfall Fossil Beds features a discovery area where children can cipher through the sand searching for their own fossil discoveries. A small barn is used for special exhibits, as well as classes.

The visitors center houses some animal remains, as well as paleontologists working on recent finds. About 60 million years before the area was home to the savanna, Nebraska was part of a tropical sea.

Fossils found in the area include a plesiosaur, a mammal from the Jurassic Period. The fossils displayed were found on the Santee reservation, about an hour away.

Sculptures representing animals from the region are located around the state historical park. Ashfall Fossil Beds State Historical Park kicks off its summer hours on Memorial Day weekend when it’s open daily through Labor Day. Otherwise, check the website here for hours.

A state park permit ($6 per vehicle for an in-state day permit or free with an annual pass) is required for visiting the park, in addition to the $7 entrance fee.

A new study shows Early Native Americans in Alaska were freshwater fishermen 13,000 years ago

A team led by the University of Alaska Fairbanks researchers has discovered the earliest known evidence that Native Americans living in present-day central Alaska may have begun freshwater fishing around 13,000 years ago during the last ice age.

Ancestors of Alaska Natives, many of whose livelihoods still depend on freshwater fish such as salmon, may have started subsistence fishing as a response to fewer food resources during long-term climate change, Ben Potter and colleagues say.

The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

“We are looking at humans as ecologists do, as biologists do,” said Ben Potter, a UAF anthropology professor and co-lead author of the paper. “Even very early on, they are able to adapt to changing conditions.”

The study, published recently in the journal Science Advances, shows that people living between 13,000 and 11,500 years ago in what is now Interior Alaska relied on freshwater fish like burbot, whitefish and pike for food. The study builds on earlier UAF findings that documented salmon fishing by the same population of ancient humans.

Native Americans have relied on freshwater fish for thousands of years, but the origins of fishing in North America have been uncertain. Beringia, a region comprising present-day Alaska and Russia, was largely ice-free during the last ice age and is considered a key gateway to the Americas.

“That discovery was really surprising because it was far from the ocean, in an area near the edge of salmon habitat,” said Potter. “That started us thinking: This could be a whole other angle on human ecology beyond large mammal hunting.”

To investigate, Potter et al. used a combination of DNA and isotope analyses to identify 1,110 fish specimens recovered from six human settlement sites – including in the Tanana, Kuskokwim, Susitna, and Copper River basins – in what was once eastern Beringia (central Alaska). They identified four main fish taxa – salmon, burbot, whitefish, and northern pike – whose earliest appearances dated to around 13,000 and 11,800 years ago.

These findings, along with well-documented fishing records from local Native Alaskans, suggest that early Native Americans may have started fishing as a response to environmental change during the Pleistocene-Holocene transition. “Our data collectively suggest that changes in climate and ultimately key mammal resources during the Younger Dryas led to human responses of widening diet breadth to incorporate multiple species of freshwater and anadromous fish, setting a pattern that would be expanded upon later in the Holocene as fish, particularly salmon, became key resources to Alaska Native lifeways,” the authors write.

The bones were found inside homes and hearths and tended to be associated with base camps, rather than short-term hunting camps. They also were far from lakes and streams, so it’s unlikely that predators moved them.

The absence of fishhooks or spears at the sites suggests that the early Alaskans likely used nets and perhaps weirs to harvest the fish.

“This is a compelling, evidence-based case for freshwater fishing at the end of the last Ice Age,” Potter said.

Until the beginning of the Younger Dryas, people relied more on waterfowl to augment large game like bison and elk. When temperatures started dropping around 13,000 years ago, that changed.

“While we don’t know why the use of waterfowl diminished, we know that the climate was changing,” Potter said. “One of the ways the people were able to adapt is to incorporate these new species and new technologies. Burbot, in particular, can be caught in late winter and early spring, when food resources were most scarce.”

The solid tie to modern subsistence activities is also compelling, he said.

Archeologists find remains of an underwater hospital and cemetery

Archeologists at Dry Tortugas National Park have found remains of a 19th-century quarantine hospital and cemetery on a submerged island. The National Park Service said in a news release that records indicate dozens of people, mostly U.S. soldiers stationed at Fort Jefferson, may have been buried there.

The small quarantine hospital was used to treat patients with yellow fever at the fort between 1890 and 1900, according to the NPS.

Major outbreaks of the disease killed dozens, but the quarantine hospital offered a place to isolate patients, likely saving hundreds of lives.

While most buried in the Fort Jefferson Post Cemetery were military members, several were also civilians.

During a survey of the area, researchers found John Greer’s grave, prominently marked with a large slab of greywacke carved into the shape of a headstone and inscribed with his name and date of death.

According to the NPS, Greer was employed as a laborer at the fort and died there on Nov. 5, 1861.

“This intriguing find highlights the potential for untold stories in Dry Tortugas National Park, both above and below the water,” project director Josh Marano said.

“Although much of the history of Fort Jefferson focuses on the fortification itself and some of its infamous prisoners, we are actively working to tell the stories of the enslaved people, women, children, and civilian laborers.”

Efforts to learn more about those buried in the cemetery are ongoing.

Genetic Study Establishes Native Ancestors Were in Alaska 3,000 Years Ago

Researchers have discovered that some modern Alaska Natives still live almost exactly where their ancestors did 3,000 years ago, highlighting genetic continuity in Southeast Alaska and shedding light on human migration patterns and pre-colonial territorial patterns in the Pacific Northwest.

The first people to live in the Americas migrated from Siberia across the Bering land bridge more than 20,000 years ago. Some made their way as far south as Tierra del Fuego, at the tip of South America. Others settled in areas much closer to their place of origin where their descendants still thrive today.

In “A paleogenome from a Holocene individual supports genetic continuity in Southeast Alaska,” published recently in the journal iScience, University at Buffalo evolutionary biologist Charlotte Lindqvist and collaborators show, using ancient genetic data analyses, that some modern Alaska Natives still live almost exactly where their ancestors did some 3,000 years ago.

Lindqvist, PhD, associate professor of biological sciences at the UB College of Arts and Sciences, is senior author of the paper. In the course of her studies in Alaska, she explored mammal remains that had been found in a cave on the state’s southeast coast. One bone was initially identified as coming from a bear. However, genetic analysis showed it to be the remains of a human female.

“We realized that modern Indigenous peoples in Alaska, should they have remained in the region since the earliest migrations, could be related to this prehistoric individual,” says Alber Aqil, a UB PhD student in biological sciences and the first author of the paper. This discovery led to efforts to solve this mystery, which DNA analyses are well suited to address when archeological remains are as sparse as these were.

Learning from an ancestor

The earliest peoples had already started moving south along the Pacific Northwest Coast before an inland route between ice sheets became viable. Some, including the female individual from the cave, made their home in the area that surrounds the Gulf of Alaska. That area is now home to the Tlingit Nation and three other groups: Haida, Tsimshian, and Nisga’a.

As Aqil and colleagues analyzed the genome from this 3,000-year-old individual — “research that was not possible just 20 years ago,” Lindqvist noted — they determined that she is most closely related to Alaska Natives living in the area today. This fact showed it was necessary to carefully document as clearly as possible any genetic connections of the ancient female to present-day Native Americans.

In such endeavors, it is important to collaborate closely with people living in lands where archeological remains are found. Therefore, cooperation between Alaska Native peoples and the scientific community has been a significant component of the cave explorations that have taken place in the region.

The Wrangell Cooperative Association named the ancient individual analyzed in this study as “Tatóok yík yées sháawat” (Young lady in cave).

Genetic continuity in Southeast Alaska persists for thousands of years

Indeed, Aqil and Lindqvist’s research demonstrated that Tatóok yík yées sháawat is in fact closest related to present-day Tlingit peoples and those of nearby tribes along the coast. Their research, therefore, strengthens the idea that genetic continuity in Southeast Alaska has continued for thousands of years.

Human migration into North America, although it began some 24,000 years ago, came in waves — one of which, about 6,000 years ago — included the Paleo-Inuit, formerly known as Paleo-Eskimos. Importantly for understanding Indigenous peoples’ migrations from Asia, Tatóok yík yées sháawat’s DNA did not reveal ancestry from the second wave of settlers, the Paleo-Inuit. Indeed, the analyses performed by Aqil and Lindqvist helped shed light on the continuing discussion of migration routes, mixtures among people from these different waves, as well as modern territorial patterns of inland and coastal people of the Pacific Northwest in the pre-colonial era.

Oral history links an ancient woman to people living in Southeast Alaska today

The oral origin narratives of the Tlingit people include the story of the most recent eruption of Mount Edgecumbe, which would place them exactly in the region by 4,500 years ago. Tatóok yík yées sháawat, their relative, therefore informs not just modern-day anthropological researchers but also the Tlingit people themselves.

Out of respect for the right of the Tlingit people to control and protect their cultural heritage and their genetic resources, data from the study of Tatóok yík yées sháawat will be available only after review of its use by the Wrangell Cooperative Association Tribal Council.

“It’s very exciting to contribute to our knowledge of the prehistory of Southeast Alaska,” said Aqil.

The secret of the mummy in the Crystal coffin found in a garage in San Francisco

Mysterious mummies are a symbol of ancient lost times, which we often associate with Egypt and other ancient civilizations. Therefore, the discovery of a coffin made of crystal with the body of a girl come from under the floor of a garage in San Francisco is absolutely shocking.

In 2016, while remodeling an old garage in San Francisco, California, workers found a strange object that, upon closer inspection, turned out to be a child’s coffin with an extraordinary design.

Rusted bolts held a metal object together that resembled a large shaped casket, and it was only by unscrewing the bolts that it was possible to identify what it was. Bolts fixed a sheet of metal that covered two windows made of thick glass. Looking inside the box, the workers were taken aback — inside lay the body of a small blonde girl, almost untouched by decay.

The discovery of an old coffin containing the body of a child terrified the people of San Francisco and perplexed scientists. It took them a long time to figure out the mystery of an unusual burial.

Coffin inside lay the body of a blond girl dressed in a lace dress. Her hair was decorated with lavender petals, and on her chest lay a wreath in the form of a cross of blue bindweeds. In her hands, she held a large purple nightshade flower.

There were no details inside the coffin that would help identify the body.  The body was examined, described, and photographed, after which the experts drew up a protocol, placed the metal coffin containing the child in a wooden box, and… handed it over to the garage owner.

According to the law, if the corpse is not a criminal and the relatives are unknown, the burial duties are assigned to the owner of the land where the body was discovered.

During the paperwork, the police gave the deceased the name Eva. And the mistress of the garage, where they found the burial, named the child Miranda.

But how did the coffin with the little dead girl end up under the garage? This was not a surprising occurrence given that the structure stood on the grounds of Odd Fellows Cemetery, San Francisco’s largest cemetery. When the rapidly growing metropolis came close to the extreme graves, a large city churchyard was closed for burials in 1890.

When the cemetery started to negatively impact the neighborhood over time, it was decided to close it down in 1923. Most of the remains were exhumed and buried in common graves, while some of the bodies were taken by relatives for reburial. The coffin with the girl was obviously forgotten in the confusion and remained in the ground, which was handed over to developers.

Tissue and hair samples were taken from the deceased girl for DNA analysis. Erica Karner was busy burying Eva-Miranda while the examination was taking place. The girl’s body began to decompose after the airtight coffin was opened. It was impossible to delay the burial.

Tissue analysis revealed that the baby’s mother was born in the British Isles. Even more interesting were the results of the hair study.

“Hair DNA analysis showed that the child had a protein deficiency and severe malnutrition.

And experts said that most likely this arose due to some kind of illness or due to the amount of medication that the child used,” the lawyer said.

Volunteers explored the city archives. They found a record of the burial of a two-year-old girl who died due to severe exhaustion. Her name is Edith Howard Cook. The child died in October 1876.

The parents’ names were Horatio Nelson and Edith Skaufi Cook. Scientists have even found living relatives of the “girl from the crystal coffin.”

Thus, volunteers and scientists were able to solve the mystery surrounding the mysterious burial and give the girl’s name back who passed away nearly 150 years ago.

Parents often embalmed their dead children’s bodies centuries ago. The famous mummy of a child is kept in Palermo’s Capuchin catacombs. Rosalia Lombardo, the daughter of a Sicilian official, died of pneumonia in 1920. The girl’s body was so well preserved that she was nicknamed “Sleeping Beauty”.

Flotsam May Be Wreckage of Historic 19th-Century Ship

 A chunk of weather-beaten flotsam that washed up on a New York shoreline after Tropical Storm Ian last fall has piqued the interest of experts who say it is likely part of the SS Savannah, which ran aground and broke apart in 1821, two years after it became the first vessel to cross the Atlantic Ocean partly under steam power.

The roughly 13-foot (4-meter) square piece of wreckage was spotted in October off Fire Island, a barrier island that hugs Long Island’s southern shore, and is now in the custody of the Fire Island Lighthouse Preservation Society. It will work with National Park Service officials to identify the wreckage and put it on public display.

“It was pretty thrilling to find it,” said Betsy DeMaria, a museum technician at the park service’s Fire Island National Seashore. “We definitely are going to have some subject matter experts take a look at it and help us get a better view of what we have here.”

It may be difficult to identify the wreckage with 100% certainty, but park service officials said the Savannah is a top contender among Fire Island’s known shipwrecks.

Explorers have searched for the Savannah for over two centuries but have not found anything they could definitively link to the famous ship. The newly discovered wreckage, though, “very well could be” a piece of the historic shipwreck, said Ira Breskin, a senior lecturer at the State University of New York Maritime College in the Bronx. “It makes perfect sense.”

Evidence includes the 1-to-1.3-inch (2.5-to-3.3-centimeter) wooden pegs holding the wreckage’s planks together, consistent with a 100-foot (30.5-meter) vessel, park service officials said in a news release.

The Savannah was 98 feet, 6 inches (30 meters) long. Additionally, the officials said, the wreckage’s iron spikes suggest a ship built around 1820. The Savannah was built in 1818.

Breskin, author of “The Business of Shipping,” noted that the Savannah’s use of steam power was so advanced for its time that the May 24, 1819, start of its transatlantic voyage is commemorated as National Maritime Day. “It’s important because they were trying to basically show the viability of a steam engine to make it across the pond,” he said.

Breskin said a nautical archaeologist should be able to help identify the Fire Island wreckage, which appears likely to be from the Savannah. “It’s plausible, and it’s important, and it’s living history if the scientists confirm that it is what we think it is,” he said.

The Savannah, a sailing ship outfitted with a 90-horsepower steam engine, traveled mainly under sail across the Atlantic, using steam power for 80 hours of the nearly month-long passage to Liverpool, England.

Crowds cheered as the Savannah sailed from Liverpool to Sweden and Russia and then back to its home port of Savannah, Georgia, but the ship was not a financial success, in part because people were afraid to travel on the hybrid vessel. The Savannah’s steam engine was removed and sold after the ship’s owners suffered losses in the Great Savannah Fire of 1820.

The Savannah was transporting cargo between Savannah and New York when it ran aground off Fire Island. It later broke apart. The crew made it safely to shore and the cargo of cotton was salvaged, but the Augusta Chronicle & Georgia Gazette reported that “Captain Holdridge was considerably hurt by being upset in the boat.”

Explorers have searched for the Savannah over the two centuries since it but have not found anything they could definitively link to the famous ship.

Until now, perhaps.

Live Civil War Shell Discovered at Pennsylvania Battlefield

Archaeologists working at a historic battlefield at Gettysburg recently made an explosive find: a live 160-year-old artillery shell that had to be detonated by a specially trained U.S. Army disposal team.

The shell was found on Feb. 8 at Little Round Top, a hill that offered Union forces a strategic position during the Civil War. On July 2, 1863, the second day of the three-day Battle of Gettysburg, the North and the South struggled for 90 minutes to control Little Round Top, leaving thousands of soldiers dead.

The rocky hill was not, however, an ideal platform for an artillery offensive, as Confederate Gen. Robert E. Lee suggested in his 1864 report about the Gettysburg campaign. Lee reported that Confederate Gen. Longstreet was delayed by Union forces firing from Little Round Top, but Longstreet decided to go around them rather than attempt to take the hill.

An 18-month-long rehabilitation project is currently taking place at Little Round Top as the National Park Service works to preserve and protect the battlefield landscape and to add new signage for Gettysburg visitors.

Archaeologist Steven Brann and his team from Stantec, a consultancy company that also performs archaeological work, were sweeping the area with metal detectors when they hit on something nearly 2 feet (0.6 meter) underground. “It is standard procedure to use metal detectors on battlefields,” Brann told Live Science in an email.

The unexploded round they discovered was about 7 inches (18 centimeters) long and weighed about 10 pounds (4.5 kilograms). “There are procedures in place in case such objects are found,” Brann explained.

Ultimately, the Army’s 55th Explosive Ordnance Disposal Company (EOD) from Fort Belvoir, Virginia, was called in to remove the shell and destroy it safely.

“Unexploded ordnance still found on the battlefield is a fairly unique circumstance,” Jason Martz, a spokesperson for Gettysburg National Military Park, told Live Science in an email. “It’s only the fifth found since 1980.” 

“Most of the objects we find are much smaller, such as percussion caps, bullets, and uniform buttons,” Brann said. “Much of what we find turns out to be modern trash or objects that were discarded during the construction of monuments, such as iron straps and nails.” Still, these artifacts are not usually discovered unless excavation is happening. And as evidenced by the current find, excavation at a battlefield can be dangerous.

“Archaeology work is always completed before any ground disturbance takes place, and it’s a federal offense to dig or metal detect for these items by the general public,” Martz said.

Many commenters and history buffs on the Gettysburg National Military Park’s Facebook post lamented the fact that the ordnance — which Capt.

Matthew Booker, commander of the EOD, identified as a 3-inch Dyer or Burton shell for a rifled cannon — had to be destroyed. 

Nonetheless, “this particular shell hasn’t told us its whole story yet,” Martz said. The park is researching the shell and its discovery location in greater detail now, trying to figure out, for example, whether it was fired by Union or Confederate troops, and will release that information to the public when it is available. 

“The fact that this shell was found nearly 160 years after the Battle of Gettysburg is a very powerful and tangible connection to the past,” Martz added. “It also reminds us that the battlefield still has stories to tell.”

Research Team Identifies Oldest Bone Spear Point In The Americas

A team of researchers has identified the Manis bone projectile point as the oldest weapon made of bone ever found in the Americas at 13,900 years.

Dr. Michael Waters, distinguished professor of anthropology and director of Texas A&M’s Center for the Study of First Americans, led the team whose findings were published this week in Science Advances.

The team studied bone fragments embedded in a mastodon rib bone which was first discovered by Carl Gustafson, who conducted an excavation at the Manis site in Washington state from 1977 to 1979.

Using a CT scan and 3D software, Waters and his team isolated all the bone fragments to show it was the tip of a weapon — a projectile made from the bone of Mastodon, prehistoric relatives of elephants.

“We isolated the bone fragments, printed them out and assembled them,” Waters said. “This clearly showed this was the tip of a bone projectile point. This is this the oldest bone projectile point in the Americas and represents the oldest direct evidence of mastodon hunting in the Americas.”

Waters said at 13,900 years old, the Manis point is 900 years older than projectile points found to be associated with the Clovis people, whose stone tools he has also studied. Dating from 13,050 to 12,750 years ago, Clovis spear points have been found in Texas and several other sites across the country.

“What is important about Manis is that it’s the first and only bone tool that dates older than Clovis. At the other pre-Clovis site, only stone tools are found,” Waters said. “This shows that the First Americans made and used bone weapons and likely other types of bone tools.”

He said the only reason the Manis specimen was preserved is because the hunter missed, and the projectile got stuck in the mastodon’s rib.

“We show that the bone used to make the point appears to have come from the leg bone of another mastodon and was intentionally shaped into a projectile point form,” Waters said. “The spear with the bone point was thrown at the mastodon. It penetrated the hide and tissue and eventually came into contact with the rib. The objective of the hunter was to get between the ribs and impair lung function, but the hunter missed and hit the rib.”

Waters studied the rib bone previously, presenting findings in a 2011 paper published in Science, in which radiocarbon dating determined the bone’s age and a genetic study of the bone fragments determined that they were mastodon.

“In our new study, we set out to isolate the bone fragments using CT images and 3D software,” he said. “We were able to create 3D images of each fragment and print them out at six times scale. Then we fit the pieces back together to show what the specimen looked like before it entered and splintered in the rib.”

Not much is known about the people who used the Manis spearpoint other than they were some of the first Indigenous people to enter the Americas. Waters said the Manis site and others are giving archaeologists some insight.

“It is looking like the first people that came to the Americas arrived by boat,” he said. “They took a coastal route along the North Pacific and moved south. They eventually got past the ice sheets that covered Canada and made landfall in the Pacific Northwest.

“It is interesting to note that in Idaho there is the 16,000-year-old Coopers Ferry site, in Oregon is the 14,100-year-old site of Paisley Caves. And here we report on the 13,900-year-old Manis site. So there appears to be a cluster of early sites in the Northwestern part of the United States that date from 16,000 to 14,000 years ago that predate Clovis. These sites likely represent the first people and their descendants that entered the Americas at the end of the last Ice Age.”
