AI reveals which predators chewed ancient humans’ bones – challenging ideas on which ‘Homo’ species was the first tool-using hunter
AI reveals which predators chewed ancient humans’ bones – challenging ideas on which ‘Homo’ species was the first tool-using hunter Researchers used AI to analyze tooth marks on ancient human fossils from Olduvai Gorge, Tanzania, which challenged the long-held idea that Homo habilis was the first tool-using hunter. The study found that the tooth marks […]

Giant ground sloths’ fossilized teeth reveal their unique roles in the prehistoric ecosystem
Giant ground sloths’ fossilized teeth reveal their unique roles in the prehistoric ecosystem Giant ground sloths, which lived in what’s now Southern California as far back as 35 million years ago, played vital roles in shaping ecosystems across the Americas before their extinction at the end of the Pleistocene. Researchers analyzed fossilized teeth from two […]

Ancient fossils show how the last mass extinction forever scrambled the ocean’s biodiversity
Ancient fossils show how the last mass extinction forever scrambled the ocean’s biodiversity Mass extinctions can have a profound impact on ocean biodiversity, as evidenced by the last mass extinction event that occurred 66 million years ago. The asteroid impact that caused this extinction event led to the loss of around 70% of species, including […]
