MIT’s New Evidence on Dinosaur Evolution
Geological evidence suggests the known dinosaur groups diverged early on, supporting the traditional dinosaur family tree. The classic dinosaur family tree has two subdivisions of…

A giant marsupial that roamed prehistoric Australia 25 million years ago is so different from its wombat cousins that scientists have had to create a…
Researchers at the University of Oslo have debunked a textbook example about how evolution proceeds during speciation. Renowned paleontologist Stephen Jay Gould fronted the old…
A new study led by researchers from the University of Bristol has shown that not all saber-tooths were fearsome predators. Saber-tooth cats, such as the…
Tanyrhinichthys mcallisteri recasts the notion of what it means to be a ‘primitive’ vertebrate, according to Penn paleontologists Lauren Sallan and Jack Stack. Sturgeon, a…
In 2011, Chilean scientists discovered a mysterious fossil in Antarctica that looked like a deflated football. For nearly a decade, the specimen sat unlabeled and…
A new study shows for the first time that the collapse of terrestrial ecosystems during Earth’s most deadly mass extinction event was directly responsible for…
