Preserved skin from Triceratops is known. This skin consist of large scales, some of which exceed 100 millimetres (3.9 in) across, which have conical projections rising from their center. A preserved piece of skin from the frill of a specimen is also known, which consists of small polygonal basement scales. [39]
There is evidence for an aggressive interaction between a Triceratops and a Tyrannosaurus in the form of partially healed tyrannosaur tooth marks on a Triceratops brow horn and squamosal (a bone of the neck frill); the bitten horn is also broken, with new bone growth after the break
Styracosaurus was a relatively large dinosaur, reaching lengths of 5–5.5 metres (16–18 ft) and weighing about 1.8–2.7 metric tons (2.0–3.0 short tons). It stood about 1.8 meters (5.9 feet) tall. Styracosaurus possessed four short legs and a bulky body. Its tail was rather short.
Ceratopsia or Ceratopia (/ ˌ s ɛr ə ˈ t ɒ p s i ə / or / ˌ s ɛr ə ˈ t oʊ p i ə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia.
Centrosaurinae (from the Greek, meaning "pointed lizards") is a subfamily of ceratopsid, a group of large quadrupedal ornithischian dinosaur.Centrosaurine fossil remains are known primarily from the northern region of Laramidia (modern day Alberta, Montana, and Alaska) but isolated taxa have been found in China and Utah as well.
The strut between this opening and the nostril was narrow in side view and transversely thickened with a straight rear edge. The processes jutting into the nostrils had hollow outer sides but were far less excavated and much higher than with Triceratops or Torosaurus. The maxilla bore at least thirty-five tooth positions. The nasal horn was low ...
In the course of the renovation of the museum's dinosaur exhibition between 2014 and 2019, the specimen was dismantled and freed from the encasing plaque. [ 8 ] [ 9 ] In the new exhibition, which was set to open in 2019, the mount was planned to be replaced by a free-standing cast and the original bones were to be stored in the museum ...
Nasal horn. Like other ceratopsid dinosaurs, Stellasaurus would have had complex cranial ornamentation. In particular, it shared similar anatomy to other derived eucentrosaurs, and has been described as having an anatomy intermediate between that of Styracosaurus albertensis and Einiosaurus, its presumed ancestor and descendant.
