85-million-year-old fossils of Argentine dinosaur found
Scientists have unearthed the fossils of a meat-eating dinosaur that roamed in Patagonia, Argentina, roughly 85 million years ago. Called Tratayenia rosalesi, the two-legged dinosaur measured about 30 feet long, based on the remains of its ribs and vertebrae. Patagonia hosted dinosaurs like the meat-eating Giganotosaurus and four-legged plant-eaters Patagotitan, Argentinosaurus and Dreadnoughtus.
