 Both "Limusaurus" and "Elaphrosaurus" have been considered basal ceratosaurians by many studies, with most of these studies considering them even more primitive than "Ceratosaurus".The most well-known elaphrosaurines lived during the Jurassic period, much older than the Late Cretaceous period noasaurines.Nevertheless, the existence of "Eoabelisaurus" shows that even abelisaurids had evolved by the Middle Jurassic, and Cretaceous elaphrosaurines such as "Huinculsaurus" have been discovered.
