In a recent study published in Palaeodiversity, researchers have uncovered a rich and varied fossil assemblage of tanystropheid archosauromorphs from the Late Triassic period, originating from the continental interior of Pangea. Among these fascinating discoveries is a newly described species, Akidostropheus oligos (gen. et sp. nov.), which has drawn attention due to its unique dorsal spike structure. This detailed study, …

Article summary Stable isotope analysis reveals ancient diets: By measuring ratios of carbon and nitrogen isotopes in bones and teeth, scientists can determine whether prehistoric individuals consumed C3 or C4 plants, and whether they were herbivores or carnivores. This technique has illuminated dietary habits from Neanderthals to early hominins. Advanced methods refine dietary insights: Techniques …

A protein that helps synthesize DNA is different in modern humans than it is in Neanderthals and Denisovans — our closest extinct relatives — and new experiments in mice genetically modified to express the modern human version hint that this may have made us behave differently. That discovery, in turn, could shed light on why Neanderthals and Denisovans vanished, researchers …

The story of human evolution is not a simple ladder from early forms to more advanced ones. For decades, fossils shaped a picture of steady, linear progress – one form giving rise to another in a neat sequence. But science often rewrites its narratives when new evidence appears. Now, remarkable finds in Ethiopia are challenging long-held assumptions and painting a …

Ancient, fossilized teeth, uncovered during a decades-long archaeology project in northeastern Ethiopia, indicate that two different kinds of hominins, or human ancestors, lived in the same place between 2.6 million and 2.8 million years ago — and one of them may be a previously unknown species. The discovery provides a new glimpse into the complex web of human evolution. Ten …

Scientists have identified a new species of ancient whale with cartoonish bulging eyes that they say would have made it look like a Pokémon. A precursor to today’s modern whale species, the 25 million-year-old creature was “deceptively cute,” according to Erich Fitzgerald, senior curator of vertebrate paleontology at Australia’s Museums Victoria Research Institute, as reported by the Toronto Sun. “It …

Fossilized teeth discovered in Ethiopia have revealed a new-to-science species of Australopithecus, a genus of early hominins that lived from the Pliocene to the Early Pleistocene. Not only does it add to our busy human family tree, but the discovery proves they were living alongside the oldest specimens of Homo, the genus of early humans that includes our species, Homo …

A biology team pitched their tents one night inside Thailand’s Kaeng Krachan National Park. While checking rocks near camp, the group lifted a flat slab and met a tiny brown scorpion, Scorpiops krachana, staring back with a startling array of eight bright eyes. Scorpiops krachan, a species new to science, was formally described and submitted for review on March 6, …
