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.
Bonaparte and Novas placed Abelisaurus in the newly created family Abelisauridae in 1985. They thought it was a member of the Carnosauria. [2] Abelisaurus was the first abelisaurid named. [5] Many other abelisaurids have since been discovered, including much more complete specimens of Aucasaurus, Carnotaurus and Majungasaurus.
Majungasaurus (/ m ə ˌ dʒ ʌ ŋ ɡ ə ˈ s ɔː r ə s /; lit. ' Mahajanga lizard ') is a genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period, making it one of the last-known non-avian dinosaurs that went extinct during the Cretaceous–Paleogene extinction event.
Carnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern landmasses of Gondwana during the late Cretaceous. Within the Abelisauridae, the genus is often considered a member of the Brachyrostra, a clade of short-snouted forms restricted to South America.

The preserved length of the excavated Skorpiovenator skeleton, measured from the premaxilla to the 12th caudal (tail) vertebra is 4.35 m (14.3 ft). Since it lacks most of the tail, precise length measurements are currently impossible, but it has been estimated to have grown up to 6–6.2 m (19.7–20.3 ft) long and weighed up to 891 kilograms (1,964 lb).
Pycnonemosaurus (meaning 'dense forest lizard') is a genus of carnivorous theropod dinosaur that belonged to the family Abelisauridae.It was found in the Upper Cretaceous red conglomerate sandstones of the Cachoeira do Bom Jardim Formation, Mato Grosso, Brazil, and it lived during the late Campanian to early Maastrichtian stage of the Late Cretaceous.
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 ...
