    Radiocarbon dating of a prehistoric archeological site in Florida suggests that 14,550 years ago, hunter-gatherers, possibly accompanied by dogs, butchered or scavenged a mastodon next to a small pond. The findings, based on a four-year study of the Page-Ladson archaeological site in the Aucilla River, about 45 minutes from Tallahassee, Florida, provide a rare glimpse of the earliest human occupation in the southeastern United States, and offer clues to the timing of the disappearance of large animals like the mastodon and camel that roamed the American Southeast during the Late Pleistocene. Additionally, the artifacts at Page-Ladson highlight that much of...

    Images: Pamela Patrick MAMMOTH HUNTER OR FISH CATCHER? Archaeologists had concluded that the first inhabitants of the New World were fur-clad big-game hunters who swept across the Bering land bridge in pursuit of their prey. But recent evidence suggests that the first settlers may have been just as likely to hunt small game, catch fish or gather plants as they moved through more temperate environments. The leaf-shaped spearpoint I'm holding is surprisingly dainty--for a deadly weapon. I let my mind wander, trying to imagine life some 14,700 years ago in the marshes of southern Chile, where this relic was ...

"Some of the bones we're finding there have collagen in them. That is where you could get the ancient DNA." The scientists saw bones falling out of a part of the cave, and decided to start digging there. "That was the fossil layer," she said. "There is so much to dig. We have two more years for funding that we can be out there, so we are going to try to...

    (Reuters) - Scientists excavating an ancient Wyoming sinkhole containing a rare trove of fossils of Ice Age mammals have unearthed hundreds of bones of such prehistoric animals as American cheetahs, a paleontologist said on Friday. The two-week dig by an international team of researchers led by Des Moines University paleontologist Julie Meachen marked the first exploration of Natural Trap Cave at the base of the Bighorn Mountains in north-central Wyoming since its initial discovery in the 1970s. Meachen said the extensive excavation that began late last month uncovered roughly 200 large bones of animals like horses that roamed North America...

    For the first time in three decades, paleontologists are about to revisit one of North America's most remarkable troves of ancient fossils: The bones of tens of thousands of animals piled at the bottom of a sinkhole-type cave. Natural Trap Cave in Wyoming is 85 feet (25 meters) deep and almost impossible to see until you're standing right next to it. Over tens of thousands of years, many, many animals—including now-extinct mammoths, short-faced bears, American lions and American cheetahs—shared the misfortune of not noticing the 15-foot-wide (4 meters) opening until they were plunging to their deaths. Now, the U.S. Bureau...

    Do earthquakes explain all those mastodon bones at Snowmass? Not likely, say scientists, although they haven’t completely shelved the idea. And did humans kill a mammoth 50,000 years ago and then cache the meat for later use? Circumstantial evidence of rocks intermixed with bones suggests that was the case. If so, it would rank as one of the major scientific discoveries of the decade, putting people on the North American continent some 36,000 years earlier than what is now generally agreed upon by archaeologists. That intriguing idea also remains on the shelf, just beyond touch for lack of corroborating evidence.

    An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland just prior to the peak of the last ice age -- 20,000 to 50,000 years ago. Beth Shapiro, the Shaffer Associate Professor of Biology at Penn State University and one of the team's leaders, explained that climate changes affecting the North Atlantic ice sheet probably gave rise to periodic overlaps in bear habitats. These overlaps then led to hybridization, or interbreeding -- an event that caused maternal DNA from brown...

    The First Americans May Have Come by Water by E. James Dixon If the foragers who created Clovis culture walked into North America, they had to pass through the long-described “ice-free corridor.” But a growing body of evidence indicates that pathway between the great glaciers of the last Ice Age was closed — in fact, the way south may have been blocked until centuries after the dawn of Clovis. If the first Americans could not walk into the New World, how did they get there? Coastal or ocean routes navigated by watercraft are the most likely explanation. No reliably dated ...

    The Clovis people, known for their distinctive spear points, likely were not the first humans in the Americas, according to research placing their presence as more recent than previously believed. Using advanced radiocarbon dating techniques, researchers writing in the journal Science on Thursday said the Clovis people, hunters of large Ice Age animals like mammoths and mastodons, dated from about 13,100 to 12,900 years ago. That would make the Clovis culture, known from artifacts discovered at various sites including the town of Clovis, New Mexico, both younger and shorter-lived than previously thought. Previous estimates had dated the culture to about...

    Who were the first people in North America? From where did they come? How did they arrive? The prehistory of the Americas has been widely studied. Over 70 years a consensus became so established that dissenters felt uneasy challenging it. Yet in 2001, genetics, anthropology and a few shards of flint combined to overturn the accepted facts and to push back one of the greatest technological changes that the Americas have ever seen by over five millennia. The accepted version of the first Americans starts with a flint spearhead unearthed at Clovis, New Mexico, in 1933. Dated by the mammoth...

    New archaeological evidence suggests that America was first discovered by Stone Age people from Europe – 10,000 years before the Siberian-originating ancestors of the American Indians set foot in the New World. A remarkable series of several dozen European-style stone tools, dating back between 19,000 and 26,000 years, have been discovered at six locations along the US east coast. Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. One is in Pennsylvania and another in Virginia.

    ST. LOUIS—The first humans to spread across North America may have been seal hunters from France and Spain. This runs counter to the long-held belief that the first human entry into the Americas was a crossing of a land-ice bridge that spanned the Bering Strait about 13,500 years ago. The new thinking was outlined here Sunday at the annual meeting of the American Association for the Advancement of Science.

They focused on the Amazon of northeastern Bolivia, where they had sediment cores from two lakes nearby major earthworks sites. These sediment cores hold ancient pollen grains and charcoal from long-ago fires, and can hint at the climate and ecosystem that existed when the sediment was laid down as far back as 6,000 years ago. An examination of the two cores — one from the large lake, Laguna Oricore, and one from the smaller lake, Laguna Granja — revealed a...

    Look around the Amazon rainforest today and it’s hard to imagine it filled with people. But in recent decades, archaeologists have started to find evidence that before Columbus’s arrival, the region was dotted with towns and perhaps even cities. The extent of human settlement in the Amazon remains hotly debated, partly because huge swaths of the 6-million-square-kilometer rainforest remain unstudied by archaeologists. Now, researchers have built a model predicting where signs of pre-Columbian agriculture are most likely to be found, a tool they hope will help guide future archaeological work in the region. In many ways, archaeology in the Amazon...

    Bird’s-Eye View of the Amazon Airborne Archaeologist Challenges the Myth of a Pristine Wilderness by Ted Mann In the office of a typical archaeologist, you would expect to find things like stone tools, pottery fragments, and maybe even a few Wooly Mammoth bones. But Clark Erickson is no typical archaeologist. Oversize rolls of aerial photographs are stacked into tubular pyramids on a desk and worktable in his University Museum office. They fill up file cabinets and populate a storage room. At last count, he had about 700 giant aerial and satellite images—almost all of them picturing some region of the...

    Amazonian find stuns researchers Deep in the Amazon forest of Brazil, archaeologists have found a network of 1,000-year-old towns and villages that refutes two long-held notions: that the pre-Columbian tropical rain forest was a pristine environment that had not been altered by humans, and that the rain forest could not support a complex, sophisticated society. A 15-mile-square region at the headwaters of the Xingu River contains at least 19 villages that are sited at regular intervals and share the same circular design. The villages are connected by a system of broad, parallel highways, Florida researchers reported in yesterday's issue of...

    Contact: Lynda Majarian lynda.majarian@uvm.edu 802-656-1107 University of Vermont Rainforest researchers hit pay dirt It shouldn't be there, but it is. Deep in the central Amazonian rainforest lies a rich, black soil known locally as terra preta do Indio (Indian dark earth) that farmers have worked for years with minimal fertilization. A Brazilian-American archeological team believed terra preta, which may cover 10 percent of Amazonia, was the product of intense habitation by Amerindian populations who flourished in the area for two millennia, but they recently unearthed evidence that societies lived and farmed in the area up to 11,000 years ago. As...

"The pilots here are very good," says Roosevelt, a veteran Amazon explorer, because the mining industry depends on them. "When I have a goal," says Anna Curtenius Roosevelt, her voice emphasizing the word, "everything else is...

    The new genetic analysis takes aim at the theory that just one founding group settled the Americas =========================================================================================================== Brazil's Surui people, like the man pictured above, share ancestry with indigenous Australians, new evidence suggests. (PAULO WHITAKER/Reuters/Corbis) ==================================================================================================================== More than 15,000 years ago, humans began crossing a land bridge called Beringia that connected their native home in Eurasia to modern-day Alaska. Who knows what the journey entailed or what motivated them to leave, but once they arrived, they spread southward across the Americas. The prevailing theory is that the first Americans arrived in a single wave, and all Native American populations...
  • Scientists Trace an Ancient Connection Between Amazonians and Australasians

    Some people in the Brazilian Amazon are very distant relations of indigenous Australians, New Guineans and other Australasians, two groups of scientists who conducted detailed genetic analyses reported Tuesday. But the researchers disagree on the source of that ancestry. The connection is ancient, all agree, and attributable to Eurasian migrants to the Americas who had some Australasian ancestry, the scientists said. But one group said the evidence is clear that two different populations came from Siberia to settle the Americas 15,000 or more years ago. The other scientific team says there was only one founding population from which all indigenous...
  • Skull Study Suggests at Least Two Groups Colonized America

    The 7,500- to 11,000-year-old remains suggest the oldest settlers of the Americas came from different genetic stock than more recent Native Americans. Modern Native Americans share traits with Mongoloid peoples of Mongolia, China, and Siberia, the researchers said. But they found dozens of skulls from Brazil appear much more similar to modern Australians, Melanesians, and Sub-Saharan Africans. A Brazilian study involving a large collection of South American skulls suggests at least two distinct groups of early humans colonized the Americas. Anthropologists Walter Neves and Mark Hubbe of the University of Sao Paulo studied 81 skulls of early humans and found...

    Thousands of years ago, a human -- probably hungry and right-handed -- found an old spear point amid these low hills and re-shaped it. Last week [in 2013] University of Cincinnati student Liz Ceddia found it again: flaked in a distinctive pattern and still sharp enough to break skin... The students are working with Ken Tankersley, a University of Cincinnati archaeology professor who first visited the area as a child. He keeps coming back to seek evidence of how climate change affects area flora and fauna. It's one of his major areas of research. Big Bone Lick State Park --...

    The genome of a young boy buried at Mal’ta near Lake Baikal in eastern Siberia some 24,000 years ago has turned out to hold two surprises for anthropologists. The first is that the boy’s DNA matches that of Western Europeans, showing that during the last Ice Age people from Europe had reached farther east across Eurasia than previously supposed. Though none of the Mal’ta boy’s skin or hair survive, his genes suggest he would have had brown hair, brown eyes and freckled skin. The second surprise is that his DNA also matches a large proportion — some 25 percent —...

    An extraterrestrial impact 13,000 years ago wiped out mammoths and started a mini-ice age, scientists believe Margaret Munro CanWest News Service Monday, May 14, 2007 A comet or some other extraterrestrial object appears to have slammed into northern Canada 12,900 years ago and triggered an abrupt and catastrophic climate change that wiped out the mammoths and many other prehistoric creatures, according to a team of U.S. scientists. Evidence of the ecological disaster exists in a thin layer of sediment that has been found from Alberta to New Mexico, say the researchers, whose work adds a dramatic and provocative twist to...
