Protoceratops were small ceratopsians, up to 2–2.5 m (6.6–8.2 ft) long and around 62–104 kg (137–229 lb) in body mass. While adults were largely quadrupedal, juveniles had the capacity to walk around bipedally if necessary. They were characterized by a proportionally large skull, short and stiff neck, and neck frill.
Ceratopsians ranged in size from 1 meter (3.3 feet) and 23 kilograms (51 pounds) to over 9 meters (30 feet) and 9,100 kg (20,100 lb). [citation needed] Ceratopsians are easily recognized by features of the skull. On the tip of a ceratopsian upper jaw is the rostral bone, an edentulous (toothless) ossification, unique to ceratopsians.
Protoceratops skull with large sclerotic rings. Based on the size of its sclerotic ring, Protoceratops had an unusually large eye among protoceratopsids. In birds, a medium-sized sclerotic ring indicates that the animal is a predator, a large sclerotic ring indicates that it is nocturnal, and the largest ring size indicates it is a nocturnal ...
Torosauridae Nopcsa, 1915. Ceratopsidae (sometimes spelled Ceratopidae) is a family of ceratopsian dinosaurs including Triceratops, Centrosaurus, and Styracosaurus. All known species were quadrupedal herbivores from the Upper Cretaceous. All but one species are known from western North America, which formed the island continent of Laramidia ...
Size comparison with human. Zuniceratops was a relatively small ceratopsian, measuring about 2.2 meters (7.2 ft) long and weighing around 175 kilograms (386 lb). [7] The basal skull length is estimated up to 40 centimetres (1.3 ft). [6] The partial proximal parietal is shown to have an inverted "T" shape, as in Protoceratops. [5]
Lokiceratops (meaning " Loki horned face") is an extinct genus of centrosaurine ceratopsian dinosaurs from the Late Cretaceous (Campanian) Judith River Formation of Montana, United States. The genus contains a single species, L. rangiformis, known from most of the skull and a partial skeleton. Four other ceratopsians are known from the same ...
Holotype skull of Magnirostris. Juvenile remains, at first tentatively named Protoceratops kozlowskii, [1] and then renamed Breviceratops kozlowskii by Kurzanov in 1990, [7] were considered to be juvenile Bagaceratops. Paul Sereno in 2000 explained this by extrapolating that the juvenile Breviceratops would grow into a mature Bagaceratops. [8]
Kosmoceratops (/ ˌkɒzməˈsɛrətɒps / [1]) is a genus of ceratopsid dinosaur that lived in North America about 76–75.9 million years ago during the Late Cretaceous period. Specimens were discovered in Utah in the Kaiparowits Formation of the Grand Staircase–Escalante National Monument in 2006 and 2007, including an adult skull and ...
