Ilokelesia aguadagrandensis
Ilokelesia, a medium-sized theropod measuring 5.3 metres (17 ft) in length,[4] is characterized by features of the skull, namely of the quadrate and postorbital bones. The vertebral series also has distinctive characters setting it apart from other abelisaurs, such as reduced processes on the cervical vertebrae and dorsal vertebrae lacking pleurocoels.[3]
I. aguadagrandensis was considered the most basal abelisaur described at the time, sharing characters, such as an expansion of the postorbital bone above the orbit and a flange of the same bone inside the orbit, with Abelisauridae and Noasauridae; but it was considered to retain primitive features for Abelisauria, such as an opening in the quadrate bone and a T-shaped postorbital.[3] A subsequent analysis has placed it within Abelisauridae, as a brachyrostran carnotaurine.[5]
Skorpiovenator bustingorryi
Skorpiovenator ("scorpion hunter") is a genus of abelisaurid theropod dinosaur from the Late Cretaceous (Cenomanian to Turonian) Huincul Formation of Argentina. It is one of the most complete and informative abelisaurids yet known, described from a nearly complete and articulated skeleton.[1]
The preserved length of the excavated Skorpiovenator skeleton from the premaxilla to the 12th caudal vertebra is 4.35 m (14.3 ft).[2] It was estimated to have grown up to 6 m (19.7 ft) in length.[1] In 2010, Gregory S. Paul gave larger estimations of 7.5 m (24.6 ft) and 1.67 tonnes (1.84 short tons).[3] In 2016, a similar size to the original estimate at 6.2 m (20.3 ft) has been estimated.[4] It had short, stubby, near-useless arms, but strong legs with powerful thighs and sturdy shins over which its large body was balanced.[5]
Skorpiovenator's skull was short, stout and covered in the ridges, furrows, tubercles and bumpy nodules that are scattered over the heads of most abelisaurid theropods. It is craniocaudally short, similar to Carnotaurus, and is shorter and deeper than the skulls of Abelisaurus and Majungasaurus. Notably, the maxilla and lacrimal of Skorpiovenator are wider than in the corresponding bones of the remaining abelisaurids.[1]
Skorpiovenator had 19 maxillary teeth, which is more than any other known abelisaurid. The shape of the crowns of the teeth is similar to other abelisaurids, and exhibit enamel wrinkles and marginal serrations.[1]
