[12] [13] Abelisaurus shares some skull features, such as a relative elongation, with the carcharodontosaurids, a group unrelated to other species assigned to the Abelisauridae, and, since it is known only from a skull, it has been suggested that future discoveries may show that Abelisaurus was in fact a carcharodontosaurid. [14]
Abelisauridae (meaning "Abel's lizards") is a family (or clade) of ceratosaurian theropod dinosaurs.Abelisaurids thrived during the Cretaceous period, on the ancient southern supercontinent of Gondwana, and today their fossil remains are found on the modern continents of Africa and South America, as well as on the Indian subcontinent and the island of Madagascar.
Ekrixinatosaurus compared in size to a human. Ekrixinatosaurus novasi is a large abelisaurid with a relatively large head and robust limbs. The combination of characteristics including a large skull, prominent supraorbital ridge above the dorsal aspect of the orbit, anteroposteriorly compressed cervical vertebrae, and robust, proportionally short hindlimbs with a tibia shorter than femur ...
Reconstruction Size compared to a human. Aucasaurus was a medium-sized abelisaur, measuring 5.5–6.2 m (18–20 ft) long and weighing approximately 700 kg (1,500 lb). [6] [7] [8] Its skull was not as short or as deep-snouted as that of Carnotaurus.
The skull was discovered slightly separated from the vertebral column. The skull and anterior presacrals were also exposed at the time of discovery and had been partially been destroyed by erosion. From the material known of the snout, only a small fragment of the right maxilla has been recovered and shows that the interdental plates are fused ...
Carnotaurus (/ ˌ k ɑːr n oʊ ˈ t ɔːr ə s /; lit. ' meat bull ') is a genus of theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 72 and 69 million years ago.
Rugops (meaning 'wrinkle face') is a monospecific genus of basal abelisaurid theropod dinosaur from Niger that lived during the Late Cretaceous period (Cenomanian stage, ~95 Ma) in what is now the Echkar Formation. The type and only species, Rugops primus, is known only from a partial skull.
Skull. The skull of Skorpiovenator, measured from the premaxilla to the quadrate, measured 54.1 cm (21.3 in) in length. [3] It was fairly short and blunt, similar to that of Carnotaurus, though was shorter and deeper than those of Abelisaurus and Majungasaurus. The antorbital fossa is less developed than in other abelisauroids.
