Carnotaurus
Carnotaurus /ˌkɑːrnoʊˈtɔːrəs/ is a genus of theropod dinosaur that lived in South America during the Late Cretaceous period, probably sometime between 72 and 69.9 million years ago. The only species is Carnotaurus sastrei. Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere. The skeleton, found in 1984, was uncovered in the Chubut Province of Argentina from rocks of the La Colonia Formation. 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. Carnotaurus was a lightly built, bipedal predator, measuring 7.5 to 9 m (24.6 to 29.5 ft) in length and weighing at least 1.35 metric tons (1.33 long tons; 1.49 short tons). As a theropod, Carnotaurus was highly specialized and distinctive. It had thick horns above the eyes, a feature unseen in all other carnivorous dinosaurs, and a very deep skull sitting on a muscular neck. Carnotaurus was further characterized by small, vestigial forelimbs and long, slender hind limbs.
Majungasaurus
Majungasaurus (/məˌdʒʌŋɡəˈsɔːrəs/; "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. The genus contains a single species, Majungasaurus crenatissimus. This dinosaur is also called Majungatholus, a name which is considered a junior synonym of Majungasaurus. Majungasaurus was a medium-sized theropod that typically measured 6–7 meters (19.7–23.0 ft) in length, including its tail. Fragmentary remains of larger individuals indicate that some adults reached lengths of more than 8 meters (26.2 ft). An allometric study in 2016 found it to be 5.6 meters (18.4 ft) long. Sampson and Witmer estimated an average weight for an adult Majungasaurus of 1,100 kilograms (2,400 lb). The specimen they based it on (FMNH PR 2100) was not the largest one discovered. Larger specimens of Majungasaurus crenatissimus could have been similar in size to its relative Carnotaurus, which has been estimated to weigh 1,500 kilograms (3,300 lb).
