Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone. [45] The use of these horns is not entirely clear. Several interpretations have revolved around use in fighting conspecifics or in killing prey, though a use in display for courtship or recognition of members of the same species is possible as well.
Example: A Ceratosaurus depicted with advanced feathers, since a skeletal feature (osteoderms) and its proximity to Carnotaurus (extensive scale impressions) imply that it lacked advanced feathers. The discovery of Kulindadromeus and integument in exceptionally preserved heterodontosaurids provides evidence for some form of filamentous ...
Relatively small compared to other North American ankylosaurs Ahvaytum: 2025 Popo Agie Formation (Late Triassic, Carnian) United States ( Wyoming) One of the oldest North American dinosaurs Akainacephalus: 2018 Kaiparowits Formation (Late Cretaceous, Campanian) United States ( Utah) Much of the skeleton is known, including the entirety of the skull
Size compared to a human. Maip is estimated to have been around 9–10 metres (30–33 ft) long in life. As such, it may be the largest megaraptorid currently known. Members of the Megaraptoridae as a whole increased in body length following the extinction of the carcharodontosaurids in the Southern Hemisphere in the early Late Cretaceous. [4]
Brachyrostrans were relatively lightly built compared to other large theropods, ranging in size from 6.1–7.8 m (20–26 ft) [3] and 1400–2000 kg (1.6–2.3 short tons) in weight. [ 3 ] [ 4 ] They are considered the most derived abelisaurids, with traits like very short, narrow skulls and extremely reduced forearms, even more so than other ...
Protoceratops skeleton at the Wyoming Dinosaur Center. The classical folklorist Adrienne Mayor has proposed that the profusion of literary descriptions and imagery of the griffin in Greek and Roman literature and art beginning in the 7th century BC to the 3rd century AD were influenced by observations and travelers' accounts of fossilized beaked dinosaur skeletons found in the Turpan and ...
Comparison between the air sacs of Majungasaurus and a bird air sacs In modern birds, pulmonary air sacs are thin-walled, translucent air-filled bags connected to the lung. Together with the lung, air sacs form a highly efficient respiratory system, which in birds is capable of extracting up to 160% more oxygen than is possible in mammals.
