A team of paleontologists from the University of Texas at Austin has uncovered fossils of an adult female Kayentatherium wellesi — an extinct tritylodontid cynodont that lived alongside dinosaurs about 185 million years ago (Jurassic period) — and her babies (at least 38 individuals). The find is among the best …

On the east coast of North America, dinosaur fossils are rare finds. Owing to several factors, such as the mass-urbanization of the eastern seaboard, fossils from these incredible creatures are few and far between. Even the most complete skeletons are incomplete, making nearly any stray chunk of bone from the …

The first complex organisms emerged during the Ediacaran period (635-541 million years ago). Ediacaran fossils are as ‘strange as life on another planet’ and have evaded taxonomic classification, with interpretations ranging from marine animals or giant single-celled protists to lichens. Fossils of one of these creatures — a flat, oval-shaped …
