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.
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.
A study in the bone histology of a mid-sized abelisaurid from the Upper Cretaceous Serra da Galga Formation is published by Aureliano et al. (2024), who report that, despite living in a semiarid tropical environment, the studied specimen had a growth rate similar to those of the Patagonian abelisaurids. [159]
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 ...

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 ...
The holotype specimen, MHNH 2024.1.1., was collected by Nicolas Cottard during two separate expeditions in 2021 and 2023, and it includes a sacrum, incomplete ilia, the first caudal vertebra, and various poorly preserved bones, possibly ribs.
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.
