Research Shows Early North Americans Made Eyed Needles from Fur-Bearers

Archaeologists from the University of Wyoming have found bone 13,000-year-old eyed needles crafted from the bones of various furry animals. The discovery sheds light on the lives of these early inhabitants of North America.

The important find comes from an important archaeological site in Wyoming, where, about 13,000 years ago, the early humans hunted a Columbian mammoth or ate its carcass.

The study, led by archaeologist Spencer Pelton, reveals that these primitive inhabitants made needles from the bones of animals such as foxes, hares, rabbits, bobcats, mountain lions, lynx, and the now-extinct American cheetah to create garments necessary for survival in a cool climate.

Paleolithic humans used the entire animal for much more than just food, which is not surprising given the harsh environment that required warm clothing. However, the 32 bone needles that were recently found provide an intricacy of craftsmanship and detail into the lives of our human ancestors.

Additionally, they identify an intriguing relationship between innovation and clothing that allowed early humans to migrate to and even survive in colder climates.

“Our study is the first to identify the species and likely elements from which Paleoindians produced eyed bone needles,” the researchers wrote. “Our results are strong evidence for tailored garment production using bone needles and fur-bearing animal pelts. These garments partially enabled modern human dispersal to northern latitudes and eventually enabled colonization of the Americas.”

The LaPrele site in Converse County preserves the remains of a killed or scavenged sub-adult mammoth and an associated camp occupied during the time the animal was butchered almost 13,000 years ago. Also discovered in the archaeological excavation — led by UW Department of Anthropology Professor Todd Surovell — was a bead made from a hare bone, the oldest known bead in the Americas.

To determine the origins of both the bone bead and the bone needles, the researchers used advanced techniques, such as zooarchaeology by mass spectrometry (ZooMS), to analyze the collagen deposits in the bones and identify the animal bones from which they were carved. The amino acids of animals in these artifacts were compared with those of animals between 13,500 and 12,000 years ago.

In presenting evidence for tailored garment production, researchers are highlighting a crucial innovation, as clothing that binds closely to the skin traps heat more effectively than draped clothing, along with stitched seams.

“Despite the importance of bone needles to explaining global modern human dispersal, archaeologists have never identified the materials used to produce them, thus limiting understanding of this important cultural innovation,” the researchers wrote.

Previous research has shown that, in order to cope with cold temperatures in northern latitudes, humans likely created tailored garments with closely stitched seams, providing a barrier against the elements.

While there’s little direct evidence of such garments, there is indirect evidence in the form of bone needles and the bones of fur-bearers whose pelts were used in the garments.

“Once equipped with such garments, modern humans had the capacity to expand their range to places from which they were previously excluded due to the threat of hypothermia or death from exposure,” Pelton and his colleagues wrote.

“Our results are a good reminder that foragers use animal products for a wide range of purposes other than subsistence and that the mere presence of animal bones in an archaeological site need not be indicative of diet,” the researchers concluded.

Oldest US firearm unearthed in Arizona, a 500-year-old bronze cannon linked to Coronado expedition

Independent researchers in Arizona have unearthed a bronze cannon linked to the 16th-century expedition of Francisco Vázquez de Coronado, and it is marked to be the oldest known firearm found in the continental United States.

The 42-inch-long, roughly 40-pound sand-cast bronze cannon was discovered at the location of a Spanish stone-and-adobe structure in the Santa Cruz Valley that is thought to have been a part of the short-lived settlement San Geronimo III.

To finance an expedition to North America in 1539, Vázquez de Coronado took out large loans and mortgaged his wife’s possessions. The Spanish conquistador and his 350 soldiers intended to locate the legendary (and nonexistent) Seven Cities of Gold north of Mexico. By 1541, they had reached southern Arizona, where they established a settlement they called San Geronimo III, or Suya. San Geronimo was the first European town in the American Southwest.

 Rather than accumulating immense wealth, Coronado and his men plied, and spent the next three years plundering, enslaving, and murdering their way across the region.

These transgressions did not go unanswered. In the predawn hours of one fateful morning in 1541, the native Sobaipuri launched a surprise attack on the town. Many settlers were killed in their beds, and the survivors fled in disarray. The cannon — meant to intimidate and protect — was never even loaded.

Although Coronado was bankrupt and facing war crime charges when his expedition came to an end in Mexico City, his impact on North America would last for many generations.

One site in particular has produced a large number of artifacts associated with the explorers, according to the authors of a study published on November 21st in the International Journal of Historical Archeology.

Researchers found European pottery, weapon parts, including a 42-inch-long bronze cannon, and glass and olive jar fragments in the ruins of a stone and adobe building in Arizona’s Santa Cruz Valley.

“Not only is it the first gun ever recovered from the Coronado expedition, but consultation with experts throughout the continent and in Europe reveal that it is also the oldest firearm ever found inside the continental USA,” Archaeologist Deni Seymour explained.

The early firearm also called a wall gun, was typically used as a defensive weapon positioned on a wooden tripod on fortification walls and required two operators. However, in Coronado’s case, such a cannon would have been used offensively, typically to pierce the weaker walls of buildings in Indigenous communities.

Archaeologists were able to date the cannon to Coronado’s time using radiocarbon dating and optically stimulated luminescence techniques, and the other artifacts matched descriptions of the supplies and possessions of his expedition.

However, the wall gun’s simple casting suggests that, in contrast to more elaborate Spanish cannons, it might have been built in Mexico or the Caribbean—and possibly even acquired from Ponce de León’s previous expedition.

Scientists Find Aztec ‘Death Whistles’ do Weird Things to the Listeners’ Brains

Scientists Find Aztec ‘Death Whistles’ do Weird Things to the Listeners’ Brains

New research reveals that one of the Aztecs’ most chilling artefacts, clay death  whistles, which resemble a human skull and produce a scream-like sound, not only frightened listeners in ancient times, but also had a profound effect on the human brain’s ability to increase states of alarm and fear.

The new study, published this month in the journal Communications Psychology, investigated the effect of these sounds on modern listeners, finding their ability to elicit negative emotional responses and increased neural activity in the auditory cortex.

For the first time, scientists investigated the effects of these disturbing whistles on the brains of modern European volunteers, conducting two separate experiments with different participant samples.

Aztec death whistles usually skull-shaped were designed to produce a high-pitched, penetrating sound similar to a scream, resulting from the collision of different air currents. Numerous examples have been found in graves dated between 1250 and 1521 CE.

Death whistles are thought to have been used by the ancient Aztecs to intimidate adversaries during battle. They are frequently found alongside the skeletons of sacrifice victims, fuelling suggestions that they might have had more of a ceremonial function.

For example, according to some experts, the death whistles were designed to resemble the piercing winds of Mictlan, the Aztec underworld that was thought to receive sacrificed tributes. Some believe the sound was intended to symbolize the Aztec God of the Wind, Ehecatl, who formed humanity from the remains of the dead.

Researchers used volunteers from modern-day Europe to perform a number of psychoacoustic tests.

When the researchers recorded the participants’ neural and psychological reactions to hearing the death scream, they found that the sound was perceived as “having a hybrid natural-artificial origin,” making it difficult for the brain to categorize.

Research participants described the sounds as “scary” e “aversive”, matching the purpose of using whistles in Aztec rituals and wars.

The psychoacoustic experiments carried out in the study revealed that the brain perceives sound as both natural and artificial, creating a feeling of ambiguity that captures mental attention.

This complex reaction involves lower-order auditory processing and higher-order cognitive systems, amplifying the emotional impact of sound.

Put another way, the death  whistle’s terrifying ambiguity seems to spark the imagination as the brain tries to decipher the sound’s symbolic meaning. The researchers therefore conclude that the whistles’ “usage in ritual contexts seems very likely, especially in sacrificial rites and ceremonies related to the dead.”

These sounds may have been intended to instill fear in victims of sacrifices or admiration to those who attended the ceremonies.

As a result, the researchers suggest that it may have been deliberately used during Aztec ceremonies to evoke strong psychological responses.

Lidar Technology Reveals a 3,000-year-old Secret Mayan City with Full of Pyramids and Plazas

Lidar Technology Reveals a 3,000-year-old Secret Mayan City with Full of Pyramids and Plazas

Tulane University researchers used laser-guided imaging to uncover vast unexplored Maya settlements in  Campeche, Mexico, revealing more than 6,500 pre-Hispanic structures, including a previously unknown large city with stone pyramids.

The ability to examine large regions from the comfort of a laboratory thanks to Light Detection and Ranging (Lidar) technology has revolutionized the way archaic researchers study ancient civilizations in recent years.

The research project, led by doctoral student Luke Auld-Thomas alongside his advisor, Professor Marcello A. Canuto, both affiliated with Tulane’s Middle American Research Institute (MARI), used Lidar technology to study an area of 130 square kilometers in Campeche.

As part of a “non-archaeological” survey, the 50-square-mile area was mapped in 2013 using lidar, a remote-sensing technology, according to a study published today in the journal Antiquity. Examining this “found” dataset, the researchers discovered the ancient city concealed in plain sight in a region teeming with Maya settlements. They found evidence of over 6,500 structures in all.

The research focuses on a part of Campeche that had previously been overlooked in traditional archaeological research.

The core of the Valeriana site contained a ballcourt and an architectural arrangement that indicated a construction date before 150 C.E.

“The government never knew about it; the  scientific community never knew about it,” says lead author Luke Auld-Thomas, an archaeologist at Tulane University, in a statement.

Researchers found not only rural areas and small communities but also a large city with pyramids, close to the only road in the area, near a village where farmers have been working among the ruins without the government or scientific community being previously aware of its existence.

The larger of the two “monumental precincts” that comprised the city “has all the hallmarks of a Classic Maya political capital,” according to the researchers. It included temple pyramids, a freshwater reservoir, several enclosed plazas that were connected, and a ball court where the Maya played games with rubber balls.

According to the study, Valeriana’s architectural layout indicates that some of the town was constructed before 150 C.E. It thrived during the Classic era, which roughly spanned 250–900 C.E. and was the Maya Empire’s golden age.

This discovery is particularly striking, as it underscores how much remains unknown about the Maya and that there is still much to uncover.

An annotated scan of Valeriana shows ruined platforms in purple and other ruined structures in black.

The researchers intend to visit Valeriana and the surrounding settlements in person to learn more about the ancient rural population of the Maya lowlands.

This study not only reveals previously unknown cities, but it also contributes to ongoing debates about the true extent of Maya settlements and their population density.

It has been contended, that prior research has mostly concentrated on sizable, well-known locations like Tikal, which may have skewed impressions of the Maya lowlands.

According to some critics, the majority of the Maya region may have been rural, with big settlements being the exception rather than the rule.

This perspective is called into question by the discoveries made in Campeche, which demonstrate how the Maya civilization created a network of communities in a vast tropical environment that varied in size and complexity.

“Lidar is teaching us that, like many other ancient civilizations, the lowland Maya built a diverse tapestry of towns and communities over their tropical landscape,” Canuto said. “While some areas are replete with vast agricultural patches and dense populations, others have only small communities. Nonetheless, we can now see how much the ancient Maya changed their environment to support a long-lived complex society.”

The Oldest Known Tombstone in the US Originally Came from Belgium, New Research has Shown

The Oldest Known Tombstone in the US Originally Came from Belgium, New Research has Shown

Jamestown, Virginia, was founded in 1607 and was the first English permanent settlement in North America.

The region has been the focus of numerous historical and archaeological investigations, such as the one conducted recently by Prof. Markus M. Key and Rebecca K. Rossi, who sought to ascertain the origin of the tombstone of the black “marble” knight of Jamestown.

The Jamestown’s black “marble” tombstone was erected in honor of a knight but the origins of the stone and the history of the knight were both unknown to historians and archaeologists. The stone dates from 1627 and is the oldest tombstone of its kind in the USA’s Chesapeake Bay area.

The tombstone is covered with carved depressions (once filled with brass inlays) that depict the outline of an English knight with a sword and shield. It was first put in place in 1627, where it remained until the 1640s when the church’s southern entrance was built.

Broken by the time it was rediscovered in 1907, the slab has been repaired and relocated to the chancel of the present-day Memorial Church.

The tombstone has undergone innumerable inspections and analyses; however, Rebecca K. Rossi and Professor Markus M. Key conducted a fresh investigation, which was just released in the International Journal of Historical Archaeology. They wished to determine the origin of the black polished limestone, commonly mis-termed “marble” that was used for the Jamestown knight’s tomb.

What they discovered was unexpected, Professor Key said.

Researchers used fossils found inside the stone to uncover a type of microfossil called foraminifera. The specific origin and time of these foraminifera species may become clear with their identification. Microfossil analysis can therefore be used in forensics to pinpoint geographic locations and is also utilized in geological studies to fine-tune the dating of rock layers.

There were six species of foraminifera identified. Many existed in what is now Belgium during the Carboniferous Period, specifically during the Viséan Age, and Middle Mississippian Epoch (which lasted from about 345 to 328 million years ago).

This shows with certainty the stone and the microfossils it contains do not actually come from the Chesapeake Bay, the USA or even North America.

According to the latest findings, the knight’s tombstone had to have been transported from Europe by sea. Based on historical evidence, it is more likely that this originated in Belgium and was shipped to London before being delivered to Jamestown, USA.

From Roman times until the present, Belgium has been recognized as the source of this Lower Carboniferous “black” marble for centuries.

“It was particularly popular among the wealthy in England during Knight’s life,” the professor said.

“Little did we realize that colonists were ordering tombstones from Belgium like we order items from Amazon, just a lot slower.”

Of the two knights who died in Jamestown in the 17th century, one was Sir Thomas West, Virginia’s first resident governor, who died in 1618 while crossing the Atlantic to Jamestown.

The second was Sir George Yeardley, who was born in Southwark in 1587 and reached Jamestown in 1610 after surviving a shipwreck near Bermuda.  Knighted on going back to England in 1617, he was appointed Governor of Virginia in 1618 and returned to Jamestown where he held this post until 1621.  He resumed the post in 1626 and died in 1627.

The tombstone is the possibility it belonged to knight Sir George Yeardley, according to historical records.

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.

In the 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.

Sleeping Beauty.

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”.

Researchers Discovered Wreckage of a Schooner that Sank in Lake Michigan in Late 1800s

Researchers Discovered Wreckage of a Schooner that Sank in Lake Michigan in Late 1800s

Maritime historians from the Wisconsin Underwater Archeology Association discovered the wreckage of a schooner that sank in Lake Michigan in the late 1800s.

The Margaret A. Muir – a 130-foot, three-masted ship built in 1872 – was found under about 50 feet (15 meters) of Lake Michigan water off Algoma, Wisconsin, according to a Wisconsin Underwater Archaeology Association (WUAA) news release.

The Muir was built at Manitowoc, Wisconsin by the Hanson & Scove shipyard for Captain David Muir.  It was intended primarily for the Great Lakes grain trade, although it carried many diverse cargoes, frequenting all five Great Lakes over her 21-year career.

The ship was en route from Bay City, Michigan, to South Chicago, Illinois, with a cargo of bulk salt. It had almost reached Ahnapee, which is now known as Algoma, when it sank during a storm on the morning of Sept. 30, 1893.

According to the Wisconsin Underwater Archeology Association, the six-member crew and Captain David Clow made it to shore in a lifeboat, but Clow’s dog went down with the ship. Captain Clow, a 71-year-old Lake veteran, had seen many wrecks in his day, but exclaimed “I have quit sailing, for water no longer seems to have any liking for me.” 

The Captain was particularly grieved at the loss of his dog, described as “an intelligent and faithful animal, and a great favorite with the captain and crew.”  The Captain remarked, “I would rather lose any sum of money than to have the brute perish as he did.”

More than a century after sinking, the Margaret A. Muir was found in about 50 feet of water in Lake Michigan in May 2024. Shown here is a rare internal view of her unusual stepped sternpost construction.

The team, including Brendon Baillod, Robert Jaeck and Kevin Cullen used historical records as well as a high resolution side scanning sonar to locate the vessel, finding its remains on May 12th, 2024.

The Margaret A. Muir was lost to history until Baillod began compiling a database of Wisconsin’s missing ships around twenty years ago.  The Muir stood out as being particularly findable. 

In 2023, Baillod approached the Wisconsin Underwater Archeology Association to undertake a search for the vessel, narrowing the search grid to about five square miles, using historical sources. 

Baillod, Jaeck and Cullen were on their final pass of the day and in the process of retrieving the sonar when they ran over the wreck in approximately fifty feet of water only a few miles off the Algoma Harbor entrance.  It had lay undetected for over a century, despite hundreds of fishing boats passing over each season.

After informing Wisconsin State Maritime Archeologist Tamara Thomsen of the discovery, the team worked for weeks to gather thousands of high-resolution photos of the location. Zach Whitrock then used these photos to create a 3D photogrammetry model of the wreck site, which enables virtual site exploration. 

The vessel is no longer intact, its sides having fallen outward after deck collapsed, but all its deck gear remains, including two giant anchors, hand pumps, its bow windlass and its capstan.

The Wisconsin Underwater Archeology Association now plans to work with the Wisconsin Historical Society’s Maritime Archeology Program to nominate the site to the National Register of Historic Places.  If accepted, it will join the schooner Trinidad, which the team located in deep water off Algoma in June of 2023.

How popcorn was discovered nearly 7,000 years ago

How popcorn was discovered nearly 7,000 years ago

How popcorn was discovered nearly 7,000 years ago
Could a spill by the cook fire have been popcorn’s eureka moment?

You have to wonder how people originally figured out how to eat some foods that are beloved today. The cassava plant is toxic if not carefully processed through multiple steps. Yogurt is basically old milk that’s been around for a while and contaminated with bacteria. And who discovered that popcorn could be a toasty, tasty treat?

These kinds of food mysteries are pretty hard to solve. Archaeology depends on solid remains to figure out what happened in the past, especially for people who didn’t use any sort of writing. Unfortunately, most stuff people traditionally used made from wood, animal materials or cloth decays pretty quickly, and archaeologists like me never find it.

We have lots of evidence of hard stuff, such as pottery and stone tools, but softer things — such as leftovers from a meal — are much harder to find. Sometimes we get lucky, if softer stuff is found in very dry places that preserve it. Also, if stuff gets burned, it can last a very long time.

Corn’s ancestors

Luckily, corn — also called maize — has some hard parts, such as the kernel shell. They’re the bits at the bottom of the popcorn bowl that get caught in your teeth. And since you have to heat maize to make it edible, sometimes it got burned, and archaeologists find evidence that way. Most interesting of all, some plants, including maize, contain tiny, rock-like fragments called phytoliths that can last for thousands of years.

Scientists are pretty sure they know how old maize is. We know maize was probably first farmed by Native Americans in what is now Mexico. Early farmers there domesticated maize from a kind of grass called teosinte.

The ancestor of maize was a grass called teosinte.

Before farming, people would gather wild teosinte and eat the seeds, which contained a lot of starch, a carbohydrate like you’d find in bread or pasta. They would pick teosinte with the largest seeds and eventually started weeding and planting it. Over time, the wild plant developed into something like what we call maize today. You can tell maize from teosinte by its larger kernels.

There’s evidence of maize farming from dry caves in Mexico as early as 9,000 years ago. From there, maize farming spread throughout North and South America.

Popped corn, preserved food

Figuring out when people started making popcorn is harder. There are several types of maize, most of which will pop if heated, but one variety, actually called “popcorn,” makes the best popcorn.

Scientists have discovered phytoliths from Peru, as well as burned kernels, of this type of “poppable” maize from as early as 6,700 years ago.

Each popcorn kernel is a seed, ready to burst when heated.

You can imagine that popping maize kernels was first discovered by accident. Some maize probably fell into a cooking fire, and whoever was nearby figured out that this was a handy new way of preparing the food. Popped maize would last a long time and was easy to make.

Ancient popcorn was probably not much like the snack you might munch at the movie theater today. There was probably no salt and definitely no butter, since there were no cows to milk in the Americas yet. It probably wasn’t served hot and was likely pretty chewy compared with the version you’re used to today.

It’s impossible to know exactly why or how popcorn was invented, but I would guess it was a clever way to preserve the edible starch in corn by getting rid of the little bit of water inside each kernel that would make it more susceptible to spoiling. It’s the heated water in the kernel escaping as steam that makes popcorn pop.

The popped corn could then last a long time. What you may consider a tasty snack today probably started as a useful way of preserving and storing food.
