After picking its victim, the T-rex charges, but the Triceratops finds it just in time and turns away to face the hungry killer. The T-rex seizes the horn of the Triceratops and breaks it off. The herbivore tries to retreat again, but the T-rex chomps on his frill. After making a loud charge, the Triceratops slashes one of his horns into the T ...
In 1966 John Ostrom postulated that the diet of late Cretaceous chasmosaurs such as Triceratops and Torosaurus fed on very resistant and fibrous materials like the fronds of cycad or palm plants. [20] By extension, all Ceratopsids had a shearing dentition and efficient, powerful jaw mechanics that allowed them to feed on tough vegetation.
Thyreophora was defined as a clade by Paul Sereno in 1998, as "all genasaurs more closely related to Ankylosaurus than to Triceratops". Thyreophoroidea was first named by Nopcsa in 1928 and defined by Sereno in 1986, as "Scelidosaurus, Ankylosaurus, their most recent common ancestor and all of its descendants". [6]
Triceratops (/ t r aɪ ˈ s ɛr ə t ɒ p s / try-SERR-ə-tops; [1] lit. ' three-horned face ') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America.
Ankylosauria is a group of herbivorous dinosaurs of the clade Ornithischia.It includes the great majority of dinosaurs with armor in the form of bony osteoderms, similar to turtles.
The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation.Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
And yes, rhinoceroses made the cut — but, says Bartsch, the one-horned Asian variety rather than the two-horned African rhino shown in the new movie.
