Abelisaurus
''Abelisaurus'' (; "Abel's lizard") is a genus of predatory abelisaurid theropod dinosaur during the Late Cretaceous Period (Campanian) of what is now South America. It was a bipedal carnivore that probably reached seven to ten meters (23 to 33 feet) in length, although this is uncertain as it is known from only one partial skull.
==Naming==
Coining the type species ''Abelisaurus comahuensis'', both genus and species were named and described by Argentine paleontologists José Bonaparte and Fernando Emilio Novas in 1985. The generic name recognizes Roberto Abel as the discoverer of the type specimen, and also as the former director of the provincial Museum of Cipolletti in Argentina, where the specimen is housed. It also incorporates the Greek σαυρος/''sauros'', meaning 'lizard'. The specific name ''comahuensis'' honors the Comahue region of Argentina, where the fossil was found.〔Bonaparte, J.F. & Novas, F.E. (1985). "''Abelisaurus comahuensis'', n.g., n.sp., Carnosauria del Crétacico Tardio de Patagonia". ''Ameghiniana''. 21: 259-265. (Spanish )〕
In 2009, Novas suggested that ''Aucasaurus garridoi'' might be a junior synonym of ''Abelisaurus''.〔Fernando E. Novas, 2009, ''The Age of Dinosaurs in South America'', Life of the Past, Indiana University Press, 480 pp〕 In 2010, Gregory S. Paul renamed ''Aucasaurus'' into a ''Abelisaurus garridoi''.〔Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press p. 79〕 This has found no acceptance.
