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.
Abelisaurus (/ ə ˌ b ɛ l ɪ ˈ s ɔː r ə s /; "Abel's lizard") is a genus of predatory abelisaurid theropod dinosaur alive during the Late Cretaceous Period of what is now South America. It was a bipedal carnivore that probably reached about 7.4 metres (24 ft 3 in) in length, although this is uncertain as it is known from only one partial ...
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.
Life restoration. Koleken is known from only the holotype MPEF-PV 10826 which was initially found and reported in 2015, [2] but was not described as K. inakayali until 2024. The holotype, consists of "closely associated (but disarticulated) remains of the skull and atlas, as well as the articulated postcranial skeleton composed of the posterior most eight dorsal vertebrae, a complete sacrum ...
Within the Abelisauridae, the genus is often considered a member of the Brachyrostra, a clade of short-snouted forms restricted to South America. Carnotaurus was a lightly built, bipedal predator, measuring 7.5 to 8 m (24.6 to 26.2 ft) in length and weighing 1.3–2.1 metric tons (1.4–2.3 short tons; 1.3–2.1 long tons).
Before discovery, the oldest known abelisaurids were represented only by fragmentary remains from the late Early Cretaceous of South America and Africa and older records of abelisauroids in general were questionable. With the discovery of Eoabelisaurus, the temporal range of the clade was extended for more than 40 million years into the ...
