Aniksosaurus (meaning "spring lizard", from Modern Greek Άνοιξη, "Spring", referring to the fact it was found on 21 September 1995, the onset of Spring on the Southern Hemisphere) is a genus of dinosaur from what is now present-day Chubut Province, Argentina. It was a theropod, specifically a coelurosaur, which lived in the middle Cretaceous period, between 96-91 million years ago.
