While excavating the ceratopsian
bone bed, we successfully uncovered several important diagnostic skull bones.
There has been a great deal of controversy in the last 20 years about whether ceratopsian
(horned) dinosaurs held their forelimbs in an essentially vertical position and were capable of galloping (Bakker, 1971, 1986; Desmond, 1976), or held their forelimbs in a more horizontal or sprawling position that would preclude galloping (Bennett and Dalzell, 1972; Coombs, 1978; Farlow and Dodson, 1975; Lehman, 1982, 1989).
It was among the earliest of the ceratopsian
line (horned dinosaurs)--and one of the smallest.
These are all key features in the identification of ceratopsian
tracks (sensu McCrea et al.
Liaoceratops] shows that the evolution of ceratopsians
is more complicated than we'd thought," says Catherine A.
It is the first specimen of the Ceratopsian
dinosaur found in the Korean peninsula.
For two decades, paleontologists have hotly debated the limb position of ceratopsian
dinosaurs, which include Triceratops.
as part of a grand reinterpretation of ceratopsian
Utahceratops and Kosmoceratops are part of a recent spate of ceratopsian
Ryan, curator and head of Vertebrate Paleontology at the Museum, published his findings on the new genus in the book, "New Perspectives on Horned Dinosaurs: The Royal Tyrrell Museum Ceratopsian
A 2m skull of a large ceratopsian
was found here, the first such discovery outside of North America, according to Xu Xing, researcher of the Institute of Vertebrate Paleontology and Paleoanthropology.
Famous dinosaurs in that area included predatory tyrannosaurs, the duck-billed hadrosaurs, heavily armored ankylosaurs, and horned dinosaurs known as ceratopsians
The armored Stegosaurus is here, as well as the homed and frilled Ceratopsians
and a Pachycephalosaur with its huge helmet of bone.
Now, the discovery of the fossils of several young dinosaurs in one small space suggests that an ancestor of ceratopsians
exhibited social behavior millions of years before their group gained large distinctive decorations.
In Alberta's Dinosaur Provincial Park, a bone bed of Centrosaurus --one of the ceratopsians
, horned dinosaurs--has been worked by Philip Currie and others from the Tyrrell Museum of Palaeontology.
