15,000 years ago, humans camped in a lush Texas valley, leaving thousands of artifacts behind, from tools to face paint. This could be definitive proof that ancient people arrived in America by boat, not by walking the Bering Strait. Anthropologist Michael Waters and colleagues announced their findings today, detailing the almost 16,000 artifacts they found near Buttermilk Creek, outside the Austin area. Their discovery will change everything you thought you knew about how people arrived in the Americas. Meet the Buttermilk Creek people What's remarkable is that this places human occupation of America over 2,000 years earlier than previously believed....

Caches of tools and animal remains from around 12,000 years ago, found on islands off the California coast, have given remarkable insight into the lives of the first Americans. The finds show fine tool technology and a rich maritime economy existed there. The tools vary markedly from mainland cultures of the era such as the Clovis. The finds, reported in Science, also suggest that rather than a land route to South America, early humans may have used coastal routes.....

<p>Some 11,500 years ago one of America's earliest families laid the remains of a 3-year-old child to rest in their home in what is now Alaska. The discovery of that burial is shedding new light on the life and times of the early settlers who crossed from Asia to the New World, researchers report in Friday's edition of the journal Science.</p>

Mexican archaeologists found three projectile points from the Clovis culture, associated with remains of a Gomphotheres – a now extinct type of elephant - dating back at least 12,000 years, in northern Sonora. The find is of major importance, as this is the first evidence in North America that this animal was contemporary with early humans. The location and date of these remains opens the possibility that in North America the Gomphotheres was still alive, in contrast with previous theories that suggest it had disappeared 30,000 years previously. The finds were made in early January at the site of ‘World’s...

CLOVIS, Calif. (AP) — It has become a never-ending heartache within the hallways of Buchanan High School: news that another former student has died in Iraq or Afghanistan. Eight former students have been killed in the two wars, including a Marine sergeant who will be laid to rest Saturday after dying Dec. 2 of a head wound in Afghanistan. The community in the heart of California's farm country has become all-too-familiar with the rituals of grief that have followed each death — tearful remembrances, flag-draped coffins, candlelight vigils. The school even built a memorial garden where the names of the...

Cranial features distinctive to Australian Aborigines are present in hundreds of skulls that have been uncovered in Central and South America, some dating back to over 11,000 years ago. Evolutionary biologist Walter Neves of the University of São Paulo, whose findings are reported in a cover story in the latest issue of Cosmos magazine, has examined these skeletons and recovered others, and argues that there is now a mass of evidence indicating that at least two different populations colonised the Americas.He and colleagues in the United States, Germany and Chile argue that first population was closely related to the Australian...

Legend Rock carries 10,000 years of profound beliefs Ice Age paintings and carvings in Europe are revered as sublime achievements of early humans, yet the prehistoric rock art in the American West is far less known. At Legend Rock in central Wyoming, 10,000 years of profound beliefs are inscribed on red sandstone cliffs. As the Pleistocene period ended approximately 12,000 years ago with the passing of the last Ice Age, people were spreading from Asia to North America and south into what is now the U.S. Archaeologists have found evidence that the early immigrants took advantage of the moderating climate...

For Darrel Higgins, finding an ancient arrowhead in a creek isn't surprising, it's actually expected. Finding a record-setting artifact that dates back to an estimated 14,000 to 18,000 years? Definitely unexpected. Higgins has been hunting creek beds for artifacts since he began finding them on farmland when he was a child. But nothing he had found compared to the 9 3/4 inch by 2 3/4 inch specimen he recently found in western Kentucky. The item, described as a clovis point made of buffalo river chert, was submerged in a creek bed when Higgins stumbled upon it. “As soon as I...

U.S. anthropologists hypothesize that ancestors of aboriginal people in South and North America followed High Arctic route Two U.S. scientists have published a radical new theory about when, where and how humans migrated to the New World, arguing that the peopling of the Americas may have begun via Canada's High Arctic islands and the Northwest Passage -- much farther north and at least 10,000 years earlier than generally believed. The hypothesis -- described as "speculative" but "plausible" by the researchers themselves -- appears in the latest issue of the journal Current Biology, which features a special series of new studies...

The secret is out: Man and gomphotheres once coexisted in Sonora. Tools and spear tips found with fossil bones at a remote Sonoran site suggest that Clovis-era hunters butchered two juvenile specimens of the elephantlike megafauna about 13,000 years ago. It's the first discovery of such recent evidence of gomphotheres in North America, said Vance Holliday, a University of Arizona anthropologist. It's also the first time gomphothere fossils were found together with implements made by Clovis people, the oldest known inhabitants of North America, Holliday said. The discovery, on a remote ranch in the Rio Sonora watershed, was actually made...

Archaeologists claim to have found the oldest known artefact in the Americas, a scraper-like tool in an Oregon cave that dates back 14,230 years.

The bed of artefacts in the state of Sonora in northwest Mexico also includes the bones of an extinct cousin of the mastodon called a gomphothere. The beast was probably hunted and killed by the Clovis people, known for their distinctive spear points, who mysteriously disappeared within about 500 years of leaving their first archeological traces. Intact Clovis camp sites and extensive evidence of hunting has been found across the United States, with the highest concentration of sites just north of the Mexican border, in the San Pedro River basin of southeastern Arizona. But relatively little is known about their...

No evidence of an extraterrestrial impact 13,000 years ago, studies say. An independent study has cast more doubt on a controversial theory that a comet exploded over icy North America nearly 13,000 years ago, wiping out the Clovis people and many of the continent's large animals.Sediments at the San Jon site, in eastern New Mexico, contained very low abundances of magnetic spherules said to be evidence of an impact.Vance Holliday Archaeologists have examined sediments at seven Clovis-age sites across the United States, and did not find enough magnetic cosmic debris to confirm that an extraterrestrial impact happened at that time,...

"The suit says the district violates the constitution in a variety of ways, including requiring students or their parents to pay fees in order to take part in curricular or extra-curricular activities in such areas as sports, cheerleading, band and choir."

Researchers have found shock-synthesized hexagonal diamonds on one of California's Channel Islands, which they say is the strongest evidence yet that a comet exploded in the atmosphere above North America, causing widespread extinctions there around 12,900 years ago... In 2007 researchers theorized that a comet set off continental fires that led to the mysterious disappearance of the Clovis people and the extermination of 35 mammal genera, including mammoths, mastodons, ground sloths and camels. The team documented a "black mat" of charcoal throughout North America that contains high levels of iridium, magnetic spheres, and nano-diamonds, which are consistent with such an...

"These findings are inconsistent with the alternative and already hotly debated theory that overhunting by Clovis people led to the rapid extinction of large mammals at the end of the ice age, the research team argues in the PNAS paper."

Migrating peoples were sophisticated in sea harvesting, Jon Erlandson says The Pacific Coast of the Americas was settled starting about 15,000 years ago during the last glacial retreat by seafaring peoples following a "kelp highway" rich in marine resources, a noted professor of anthropology theorized Wednesday. Jon Erlandson, director of the Museum of Natural and Cultural History at the University of Oregon, suggested that especially productive "sweet spots," such as the estuaries of B.C.'s Fraser and Stikine rivers, served as corridors by which people settled the Interior of the province. Erlandson said in an interview these migrating peoples were already...

Cache of tools found in Boulder yard used to butcher ice-age camels, horses. The “chink” of the impact sounded odd, so the crew poked around, and just 18 inches beneath the soil surface they made an extraordinary find: 83 stone tools left in a cache 13,000 years ago by people who used the sharpened rocks to butcher ice-age camels. “Sometimes they’re interesting things, and sometimes they’re just cool rocks,” said Bamforth, who studies the culture and tools of Paleoindians, who lived in the Boulder area at the end of the last ice age. But a good anthropologist leaves no rock...

Landscapers were digging a hole for a fish pond in the front yard of a Boulder home last May when they heard a "chink" that didn't sound right. Just some lost tools. Some 13,000-year-old lost tools. They had stumbled onto a cache of more than 83 ancient tools buried by the Clovis people — ice age hunter-gatherers who remain a puzzle to anthropologists. The home's owner, Patrick Mahaffy, thought they were only a century or two old before contacting researchers at the University of Colorado-Boulder. "My jaw just dropped," said CU anthropologist Douglas Bamforth, who is leading a study of...

Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team. These nanodiamonds, which are produced under high-temperature, high-pressure conditions created by cosmic impacts and have been found in meteorites, are concentrated in similarly aged sediments at Murray Springs, Ariz., Bull Creek, Okla., Gainey, Mich., and Topper, S.C., as well as Lake Hind, Manitoba, and Chobot, Alberta, in Canada. Nanodiamonds can be produced on Earth, but only through high-explosive detonations or...
