After reviewing decades of mounting evidence, researchers documented around 150 morphological differences across multiple supposed juvenile T. rex skeletons. Instead of young dinosaurs, these were actually adult examples of an entirely separate species now known as Nanotyrannus
It’s a fungi-filled world and we are just living in it. There are roughly 150,000 to 157,000 known species of fungi, and now there is a new giant species to add to that tally. A team of scientists exploring the forests of Yunnan in southern China discovered the new fungus, which shows just how large
Contrary to the assumptions of early paleontologists, most dinosaurs weren’t lumbering slowpokes. Centuries of evolutionary reevaluation now indicates the ancestors of present-day birds didn’t simply keep a steady pace—many of them boasted impressive speed. These active lifestyles also forced scientists to reconsider another anatomical detail. Once thought universally cold-blooded, a lot of dinosaurs eventually evolved
