Noasaurus leali

Noasaurus leali

Noasaurus leali was a gracile, agile ceratosaurian theropod that inhabited the Late Cretaceous floodplains of what is now northwestern Argentina. Historically famous for a curved claw once mistakenly placed on its foot like a dromaeosaurid, anatomical re-evaluation revealed this raptorial ungual actually tipped its grasping hand. As a fast-moving hunter, it pursued small vertebrates across seasonal waterways, occupying a fleet-footed predatory niche overshadowed by gigantic apex abelisaurids.
