Bearing a large bony frill, three horns on the skull, and a large, four-legged body, exhibiting convergent evolution with bovines and rhinoceroses, Triceratops is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around 8–9 m (26–30 ft) long and weighing up to 6–10 t (5 ...
Most restorations of ceratopsians show them with erect hindlimbs but semi-sprawling forelimbs, which suggest that they were not fast movers. But Paul and Christiansen (2000) argued that at least the later ceratopsians had upright forelimbs and the larger species may have been as fast as rhinos, which can run at up to 56 km or 35 miles per hour ...
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 during most of the Late ...
The lack of a nose horn, present in many ceratopsians, lessens the likelihood that Lokiceratops used its horns to defend against predators, according to paleontologist and study co-lead author ...
Einiosaurus is a genus of herbivorous centrosaurine ceratopsian dinosaur from the Upper Cretaceous (Campanian stage) of northwestern Montana.The name means 'bison lizard', in a combination of Blackfeet Indian eini and Latinized Ancient Greek sauros; the specific name (procurvicornis) means 'with a forward-curving horn' in Latin.
Other research examining juvenile ceratopsians reveals a change in horn morphology over time, suggesting frills and horns could have been used for intraspecific communication of age. [30] Horns also could have been used for thermoregulation as indicated by isotope analysis , [ 31 ] as aid in knocking down vegetation, [ 32 ] or for horn-locking ...
S saegusai belongs to a group of herbivorous dinosaurs called ceratopsians, known for large horns and frills on their heads. It is the easternmost dinosaur of its kind found in Asia. It is the ...
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]
