Other large herbivores, such as three - horned ceratopsians and armored ankylosaurs, also roamed the area (SN: 6/24/17, p. 4).

His study, published in the journal Cretaceous Research, highlights it as the first fossil from a ceratopsian dinosaur identified from this period of eastern North America.

Many general discussions of ceratopsian ornaments in museum signage and popular literature often include examples of what they might have been for, but these tend to be rather speculative.

The researchers believe the implications extend beyond the scope of ceratopsians and have consequences for the study of evolutionary theory over vast stretches of time.

You would expect that when a lot of ceratopsian species lived side by side, they would evolve a bigger variation of ornaments than more solitary species.

Andrew Knapp, PhD candidate from the School of Biological and Chemical Sciences and lead author of the study, said: «This resolves a long - standing and hitherto untested hypothesis concerning the origin and function of ornamental traits in ceratopsian dinosaurs.

A previous research paper from Queen Mary found that the frill in one ceratopsian species, Protoceratops, may have evolved under sexual selection.

Triceratops, for example, belongs to a big group of species called ceratopsians, many of which had frills and horns in a dizzying variety of shapes and sizes.

Because Wendiceratops is more closely related to a different group of ceratopsians than Triceratops — one that includes the recently discovered «Hellboy» dinosaur — the discovery suggests that the tall and high version of the nose horn evolved twice in the ceratopsian family.

But the scientists say that the most important trait is a tall horn on its nose, the earliest sighting of this feature that characterized later ceratopsians.

As the researchers report online today in PLOS ONE, the 6 - meter - long beast (artist's conception above) had the typical ceratopsian features of a frilly crown behind its head and probably had horns over its eyes.

Now, a team working in Canada's Alberta province, near the border with Montana, reports finding a 79 - million - year - old ceratopsian they call Wendiceratops pinhornensis («Wendi» after the Alberta fossil hunter Wendy Sloboda, who discovered the site where the fossils were found, and «pinhornensis» after the name of the site locality, the Pinhorn Provincial Grazing Reserve in Alberta).

The ceratopsians, horned and frilled dinosaurs that include the famous Triceratops, were one of the most successful and widespread dino groups, especially between about 90 million and 66 million years ago.

Many paleontologists have maintained that the horns of ceratopsians were rhinolike, and Witmer can now test that hypothesis.

In most dinosaur art before the 1980s, ceratopsians dragged their bellies under legs crooked out to the sides.

But Peter Dodson, a ceratopsian expert at the University of Pennsylvania, argues the proper pose is crook - legged, not necessarily in the «extreme push - ups» pose of modern crocodiles, but certainly not in the straight pillar fashion of modern rhinos either.

One major controversy with ceratopsians (the family of Triceratops and Protoceratops) is whether they stood on straight legs like rhinos or crouched crook - legged like crocodiles.

According to Dodson's reading of bones, all straight - legged ceratopsian reconstructions suffer from painful shoulder dislocations.

They were a diverse bunch, including the rhinolike ceratopsians and bipedal duck - billed dinosaurs such as Parasaurolophus.

Universal Pictures have offered a very cool photo opportunity, recreating a small diorama of the first promotional still from the film, bringing in a large Ceratopsian skull for maximum wow factor!

Also, ACTUAL * sauropod *, and * ceratopsian *, feet look more like THIS, and THIS:

They appear as a metallic mono - ceratopsian skull embedded in black rock.
