Instead, the team determined that the shape of the cut marks was consistent with those made by stone tools. “The cut marks were not randomly distributed but focused on those skeletal elements that harbored large muscle packs like the pelvis and the tail,” he said. A detailed examination of cut marks on the fossils revealed they were made by stone tools in a deliberate sequence. Along with three perforated giant sloth bones found in Brazil that archaeologists believe humans used as pendants 25,000 to 27,000 years ago, the butchered armadillo bones suggest that humans were in South America a surprisingly long time ago. “Until recently, the traditional model indicated that humans entered the continent 16,000 calendar years ago,” he said.

☆ Stone Age Paleo diet was not rich in meat, scientists say

CNN —What did people in the Stone Age eat before the advent of farming around 10,000 years ago? Scientists analyzed chemical signatures preserved in bones and teeth belonging to at least seven different Iberomaurusians and found that plants, not meat, were their primary source of dietary protein. The evidence suggested that the Iberomaurusians consumed “fermentable starchy plants” such as wild cereals or acorns, according to the study. The work undermines the idea that a Stone Age diet was meat heavy — a rigid assumption perpetuated by present-day dietary trends like the Paleo diet. The transition to agriculture was a complex process that occurred at different times and proceeded at different rates, in different ways with different foods, in different places, Pobiner said.

☆ Scientists use cosmic rays to date earliest evidence of humans in Europe

Archaeologists have recovered 90,000 stone tools from the site, which lies close to Ukraine’s southwestern border with Hungary and Romania. Some 90,000 stone tools made by early humans have been found at the site but no human fossils. Garba‘s colleagues measured two nuclides, aluminum-26 and beryllium-10, found in quartz grains from seven pebbles discovered in the same layer as the stone tools. The earliest human fossils unearthed in Europe are from the Atapuerca site in Spain and date back 1.1 million years, according to the study. Korolevo would have been appealing to ancient humans because it’s near the Tisza River, which leads to the Danube, and there was a readily available source of hard rock to knap stone tools, Garba said.

☆ 27,000-year-old pendants crafted from the skin of extinct giant sloths could help rewrite the human history of the Americas

Researchers found what appeared to be pendants made from the now-extinct giant sloth. It suggests humans lived in South America thousands of years earlier than previously thought. "It's very likely that multiple waves of people came to Americas," she said, according to The AP. Giant ground sloths could reach 13 feet long, weighed more than a thousand pounds and were equivalent in size to an Indian elephant. It walked on all fours and was one of the largest creatures in South America, per the report.

☆ Cannibalism, or ‘Clickbait’?
▼ + stars: | 2023-07-01 | by ( Franz Lidz | ) www.nytimes.com time to read: +2 min

Everybody’s quick to see a cannibal. The Romans thought the ancient Britons feasted on human flesh, and the British thought the same about the Irish. Not a few prehistoric finds have been attributed, evocatively if not accurately, to the work of ancient cannibals. The news release described the finding as the “oldest decisive evidence” of such behavior. Or, put another way, How much premodern evidence is needed to prove a modern theory?

☆ Butchery marks on a fossilized bone suggest human ancestors ate each other, shocking researchers

A researcher found what appear to be cut marks on the bone of a human ancestor. I was really not expecting to find these sorts of cut marks." Almost all of the bone's marks could be classified as cut marks with a high degree of confidence, Pobiner said. Not all cut marks mean cannibalismTwo marks (5 and 6) were identified as tooth marks, and the rest were identified as cut marks. Pobiner hopes the findings will inspire other researchers to return to existing collections to look for more cut marks.

☆ Cut marks on fossilized bone may reveal ancient cannibalism
▼ + stars: | 2023-06-26 | by ( Katie Hunt | ) edition.cnn.com time to read: +5 min

CNN —Nine cut marks on a fossilized shin bone suggest that ancient human relatives butchered and possibly ate one another 1.45 million years ago, according to a new study. “These cut marks look very similar to what I’ve seen on animal fossils that were being processed for consumption,” Pobiner said in a news release. Jennifer ClarkWhat the cut marks revealStudy coauthor Michael Pante, a paleoanthropologist at Colorado State University, created 3D models based on molds of marks on the bone. He said cut marks were reported on the cheek bone of a hominin fossil found in Sterkfontein, South Africa, in 2000 that could be about 2 million years old. Pobiner, however, said the source of the cut marks in that case was disputed.
