Dromomeron gregorii is a possible ancestor of pterosaurs
An article published in the journal “Nature” reports a study on Dromomeron gregorii, an archodon reptile that lived just over 210 million years ago, in the Triassic period. A team of researchers subjected recently discovered fossil skulls of this species to a micro-CT scan to reconstruct the structure of their brains and sensory systems. This allowed them to detect many similarities with pterosaurs that, together with other anatomical similarities, convinced them that they’re the ancestors of these flying reptiles.
