Chasmosaurus was a herbivore (plant-eater) that lived in the late
Cretaceous period,
betweenabout 76 million and 70 million years ago,
Chasmosaurus was about 16 to 20 feet (5 to 6 meters) long, and weighed roughly 4 tons.
A specimen found by
Charles H. Sternberg in
1913,
even includes some
fossilized skin
impressions - and from these it is believed that Chasmosaurus had
rows of bony knobs (osteoderms) in parts of its skin.
When Chasmosaurus was first discovered in 1898 by Lawrence Lambe, it was initially
believed to be a new species of Monoclonius.
It was only after further
fossils were found in
1913
and
1914,
that it was realized that it was a separate genus.
Additionally, when
Agujiaceratops
was discovered in
1938,
it was believed to be a species of Chasmosaurus, and it was only when further
Agujiaceratops
fossils were found in
1991,
that Agujiaceratops was placed in a separate genus from Chasmosaurus.
