Abelisaurus comahuensis, the type species

Abelisauroidea is a clade of creatosaurian theropod dinosaurs, a clade that includes also some formes as Abelisaurus, the type species, but also Carnotaurus, Aucasaurus and Tarascosaurus.

Abelisauroids have their origins in the middle Jurassic South America, and have became slowly the most successful predators in the Southern Hemisphere. They already got extincted in North America and Asia, wiped out by Tyrannosaurs , when the clade finally died out in the late Cretaceous.

CharacteristicsEdit

General characteristicsEdit

Abelisauroids were overall medium to big-sized dinosaurs, the biggest abelisaurid possibly being Ekrixinatosaurus novasi, at 10-11meters (or 33-36ft) long, despite recently in Afrca is recovered a possibly larger Abelisaurid. 

Abelisauroids were bulky animals, with large trunks, large, short heads, with a relatively strong bite. They had very tiny arms with 3-4-fingered hands, their hands being even smaller than those of Tyrannosaurs. They also were pretty fast-runners, as theiy had long legs.
