Why big dinosaurs steered clear of the tropics

The study reveals that wild climate swings in the tropics made it difficult for large, warm-blooded dinosaur herbivores to survive. The researchers found that wildfires swept the landscape during arid regimes, continually reshaping vegetation available for plant-eating animals.

Lethal wounds on skull may indicate 430,000-year-old murder

A nearly complete skull from the Sima de los Huesos cave site in northern Spain shows two penetrating lesions that may indicate an act of lethal interpersonal aggression around 430,000 years ago. The injuries are unlikely to be caused by a fall and suggest early evidence of funerary behavior.

Scientists discover world's oldest stone tools

The discovery of stone tools in northwestern Kenya pushes the known date back by 700,000 years and may challenge the notion that modern humans' ancestors were the first to create such tools. The tools suggest an earlier group of proto-humans may have had the thinking abilities needed to figure out how to make sharp-edged tools.

Neanderthals manipulated the bodies of adults and children shortly after death

Scientists have discovered that Neanderthals from the French region of Poitou-Charentes performed perimortem corporal manipulations on adults and children, including cutting, beating, and fracturing bones. The bone fragments analyzed show clear signs of these manipulations, which may be related to rituals or cannibalism.

Meet the gomphothere: UA archaeologist involved in discovery of bones of elephant ancestor

Researchers from the University of Arizona have discovered two juvenile gomphotheres at an archaeological site in northwestern Mexico, dating back 13,400 years. The findings suggest that early humans in North America likely hunted and consumed gomphotheres, expanding our understanding of their diet and behavior.

Science magazine publishes study on new fossil human skulls from Spanish site

A recent study on Sima de los Huesos fossils in northern Spain confirms the mosaic evolution pattern of Neandertal skull development. The analysis reveals homogeneity among the fossil sample, allowing researchers to study individual variation and growth patterns, shedding light on human evolution during the Middle Pleistocene.

Neolithic mural may depict ancient eruption

Scientists analyzed volcanic rock samples from Turkey's Hasan Dagi volcano and found ages that overlap with the estimated time of a Çatalhöyük Neolithic site mural. The mural is believed to depict an explosive eruption of the volcano, which closely matches the dated timeline.
