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.
Recent fossil evidence in the form of isolated large abelisaurid bones and comparisons with other similarly aged deposits elsewhere in Africa indicates that the fauna of the Kem Kem Group (specifically in regard to the numerous predatory theropod dinosaurs) may have been mixed together due to the harsh and changing geology of the region, when ...
Many other abelisaurids have since been discovered, including much more complete specimens of Aucasaurus, Carnotaurus and Majungasaurus. They showed that abelisaurids were not carnosaurs in the modern sense, but belonged to the Neoceratosauria instead. Some scientists place Abelisaurus as a basal abelisaurid, outside the subfamily Carnotaurinae.
This is a list of non-avian dinosaurs whose remains have been recovered in Africa.Africa has a rich fossil record. It is rich in Triassic and Early Jurassic dinosaurs. . African dinosaurs from these time periods include Megapnosaurus, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesoth
New fossil material of ceratosaur theropods, probably representing one of the oldest known record of abelisaurids, is described from the Upper Jurassic Cañadón Calcáreo Formation by Rauhut & Pol (2021). [149] A study on the skeletal anatomy and phylogenetic relationships of Xenotarsosaurus bonapartei is published by Ibiricu et al. (2021).
Some paleontologists have postulated that a large desert may have kept abelisaurids locked in southern Gondwana until the late Jurassic. [2] Whether correlation or causation, it has been largely observed that late Cretaceous ceratosaurs were found less in areas dominated by basal tetanurans (Africa) or coelurosaurs (North America and Asia). The ...

Formally described in 2009, the type specimen is one of the most complete and informative abelisaurids yet known, described from a nearly complete and articulated skeleton. A tibia fragment was assigned to Skorpiovenator in 2022. Skorpiovenator was a fairly large abelisaurid. What is preserved of the type specimen measures 4.35 m (14.3 ft) in ...
