 Data for the abelisaurid forelimbs are known from Eoabelisaurus and the carnotaurines Aucasaurus, Carnotaurus and Majungasaurus. All had small forelimbs which seem to have been vestigial. The bones of the forearm (radius and ulna) were extremely short, only 25 % of the length of the upper arm (humerus) in Carnotaurus and 33 % in Aucasaurus. The entire arm was held straight, and the elbow joint was immobile.
