Abelisaurus (/əˌbɛlɪˈsɔːrəs/; "Abel's lizard") is a genus of predatory abelisaurid theropod dinosaur alive during the Late Cretaceous Period (Campanian) of what is now South America. It was a bipedal carnivore that probably reached about 7.4 metres (24 ft 3 in) in length, although this is uncertain as it is known from only one partial skull.
