Dinosaurs like Tyrannosaurus have long been portrayed with their big teeth bared. But new research suggests this wasn’t so.
Alexis Mychajliw’s science is driven by her love of animals. She now looks to tar pits and fossilized poop to understand ancient ecosystems.
Neandertals are an extinct species closely related to modern humans. They made tools and jewelry, controlled fires and cared for their sick.
From toolmaking to healthcare, new research finds that Neandertals shared many cultural and social similarities with our human ancestors.
These ancient flying reptiles were not dinosaurs, but they were close relatives.
A new analysis of an old fossil supports the idea that winged pterosaurs evolved from swift and tiny two-legged ancestors.
Svante Pääbo figured out how to examine the genetic material from these hominid ‘cousins’ of modern humans.
Developing in the womb for a while — but being born ready to take on the world — may have helped post-dinosaur mammals rise to dominance.
A predecessor to Tyrannosaurus rex, Meraxes gigas had a giant head. But the muscularity of its puny arms suggests those limbs served some purpose.
The newly discovered Thiomargarita magnifica is about the size of your eyelash and is surprisingly complex.
