Palaeontologists have found what is likely to be the oldest known dinosaur, filling in a yawning evolutionary gap. A study in Biology Letters describes Nyasasaurus parringtoni, a new species from 10-15 million years before the previous earliest dinosaur specimens.
When dinosaurs came into existence nearly 230m years ago, all of the world's land masses were joined in one C-shaped supercontinent, Pangaea. Of course, these earliest dinosaurs may have only lived in certain parts of Pangaea, and the oldest known specimens were all discovered in what is now Argentina.
