Paleontologists uncovered a strange new dinosaur a few years ago—a crazy, patchwork quilt of a creature dubbed Chilesaurus diegosuarezi. Its bizarre and often conflicting characteristics defied classification, forcing scientists to make an educated guess about its place on the dino family tree. New research suggests…
Paleontologists working in Argentina uncovered the remains of a Cretaceous-era dinosaur that featured the same kind of miniaturized arms found on the T. rex. These ancient creatures weren’t closely related, so scientists now suspect that tiny arms evolved independently.
Injuries are common in the fossilized remains of dinosaurs, but the recent discovery of a severely roughed-up skeleton in Arizona establishes a new record for the most bone injuries sustained by a single theropod. This guy got wrecked.
If you thought Jurassic World had the craziest picture of dinosaur behavior, get ready to be reminded that reality can always get weirder. Researchers have found evidence that dinosaurs danced, both to terrify their enemies and impress their would-be lovers.
Paleontologists have known for years that Tyrannosaurus Rex and other closely related theropods had jagged teeth to help them chew through flesh. But close inspection of crack-like features at the base of these serrations has revealed there’s more to these fearsome teeth than previously believed.
Meet Chilesaurus diegosuarezi, a newly described dinosaur discovered by a seven-year-old boy in Chile. The theropod was related to famous meat-eaters like T. rex, but researchers think it was a vegetarian. Stranger still: It possessed a mixture of anatomical features unlike anything researchers have seen before.
When I was a child, no dinosaur had feathers. Nowadays it seems like they're putting feathers on everything. And while feathered dinosaurs can certainly be cool . . . where did this all come from? Which dinosaurs had feathers, and which ones can I still imagine as scaly reptilian monsters?
Meet Nanuqsaurus hoglundi. Based on its 25-inch-long skull, its body was probably half the length of a Tyrannosaurus Rex's, but this petit tyrannosaurid was an apex predator of the Arctic.
