Centrosaurus
''Centrosaurus'' ( ; ) is a genus of herbivorous ceratopsian dinosaur from the Late Cretaceous of Canada. Their remains have been found in the Dinosaur Park Formation, dating from 76.5 to 75.5 million years ago. Discovery and naming The first ''Centrosaurus'' remains were discovered and named by paleontologist Lawrence Lambe in strata along the Red Deer River in Alberta, Canada. The name ''Centrosaurus'' means "pointed lizard" (from Greek ', , "point or prickle" and ', , "lizard"), and refers to the series of small hornlets placed along the margin of their frills, not to the nasal horns (which were unknown when the dinosaur was named). The genus is not to be confused with the stegosaur '' Kentrosaurus'', the name of which is derived from the same Greek word. Later, vast bonebeds of ''Centrosaurus'' were found in Dinosaur Provincial Park, also in Alberta. Some of these beds extend for hundreds of meters and contain thousands of individuals of all ages and all leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monoclonius
''Monoclonius'' (meaning "single sprout") is a dubious genus of herbivorous ceratopsian dinosaur found in the Late Cretaceous layers of the Judith River Formation in Montana, United States, and the uppermost rock layers of the Dinosaur Park Formation in Alberta, Canada dated to between 75 and 74.6 million years ago. ''Monoclonius'' was named by Edward Drinker Cope in 1876. Later, much taxonomic confusion was caused by the discovery of '' Centrosaurus'', a very similar genus of ceratopsian that is known from much better remains. Today, typical ''Monoclonius'' specimens are usually believed to be juveniles or subadults, in many cases of other genera such as ''Centrosaurus''. Those specimens that remain under the name ''Monoclonius'' are mostly too incomplete or immature to be confidently matched with adult specimens from the same time and place. This is especially true of the type species, ''Monoclonius crassus''. Therefore, ''Monoclonius'' is now usually considered a ''nomen dubi ...

Hilda Mega-bonebed
The Hilda mega-bonebed is a complex of fourteen probable ''Centrosaurus apertus'' bonebeds discovered near the town of Hilda in Alberta, Canada. It was first described in the scientific literature by David Eberth, Donald Brinkman, and Vaia Barkas in 2010 after more than ten years of research. The Hilda mega-bonebed is significant because the behavior of the preserved dinosaurs themselves was the dominant cause of its existence, rather than the stratum's geological history like most bonebeds. It is also Canada's largest bonebed. History of research In 1959, Wann Langston, Jr. recorded evidence of a ''Centrosaurus'' bonebed near Hilda, Alberta. Later, between 1964 and 1966 Don Taylor of the Provincial Museum of Alberta (now called the Royal Alberta Museum) oversaw the collection of fossils from yet another bonebed in the same region. These prospective bonebeds attracted the attention of scientists working for the Royal Tyrell Museum in the 1990s because Hilda was an ideal locatio ...

Styracosaurus
''Styracosaurus'' ( ; meaning "spiked lizard" from the Ancient Greek / "spike at the butt-end of a spear-shaft" and / "lizard") is a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period (Campanian stage), about 75.5 to 74.5 million years ago. It had four to six long parietal spikes extending from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to long and wide. The function or functions of the horns and frills have been debated for many years. ''Styracosaurus'' was a relatively large dinosaur, reaching lengths of and weighing about . It stood about tall. ''Styracosaurus'' possessed four short legs and a bulky body. Its tail was rather short. The skull had a beak and shearing cheek teeth arranged in continuous dental batteries, suggesting that the animal sliced up plants. Like other ceratopsians, this dinosaur may have been a herd animal, travelling in large groups, as sug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coronosaurus
''Coronosaurus'' is a genus of centrosaurine ceratopsian dinosaurs which lived in the Late Cretaceous, in the middle Campanian stage. Its remains, two bone beds, were discovered by Phillip J. Currie in the Oldman Formation of Alberta, Canada, and its type and only species, ''Coronosaurus brinkmani'', was first described in 2005, as a new species within the genus ''Centrosaurus''. Later studies questioned the presence of a direct relationship, and in 2012 it was named as a separate genus. ''Coronosaurus'' means "crowned lizard", coming from "''corona''", Latin for crown, and "''sauros''", Greek for lizard; this name refers to the unique, crown-like shape of the horns on the top of its frill. Like other ceratopsids, ''Coronosaurus'' had a large frill and horns on its head. These include a small pair of brow horns over its eyes, a large nasal horn on its snout, and, unique among ceratopsians, irregular, spiky bone masses on its frill. Growing up to around long and in weight, it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
