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).
Rajasaurus
Rajasaurus is a genus of carnivorous abelisaurid theropod dinosaur from the Late Cretaceous of India, containing one species: Rajasaurus narmadensis. The bones were excavated from the Lameta Formation in the Gujarat state of Western India, probably inhabiting what is now the Narmada River Valley. It was formally described by palaeontologist Jeffrey A. Wilson and colleagues in 2003 based on a partial skeleton comprising the braincase, spine, hip bone, legs, and tail–a first for an Indian theropod. The dinosaur likely measured 6.6 metres (22 ft), and had a single horn on the forehead which was probably used for display and head-butting. Like other abelisaurids, Rajasaurus was probably an ambush predator. In 2010, palaeontologist Gregory S. Paul estimated the body length of Rajasaurus at 11 metres (36 ft) and weight at 4 metric tons (4.4 short tons). In 2016, its length was estimated to be 6.6 metres (22 ft). The same year another estimation listed it at 10.5 metres (34.5 feet) and 3 metric tons (3.3 short tons). Rajasaurus closely resembled the Madagascan abelisaurid Majungasaurus, with a 20 million year separation. Abelisaurids typically had four fingers, short arms, and, to compensate, a heavily-constructed head which was the primary tool for hunting; however, the skull was short, they probably had modest jaw musculature, and the teeth were short. Abelisaurids probably had a bite force similar to Allosaurus at around 3,500 newtons (790 lbf).
