Chasmosaurus
Click here for more Chasmosaurus Pictures
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.

Here is a summary of some of the key facts about Chasmosaurus:
- Chasmosaurus was a genus of dinosaur.
- "Chasmosaurus" means "opening lizard" (referring to the openings in its neck frill).

- Chasmosaurus was a Ceratopsian - a member of a group of related herbivorous (plant-eating) dinosaurs with beaks, many of which had neck frills and horns as well.
- Chasmosaurus lived between about 76 million years ago and 70 million years ago, during the late Cretaceous period.
- Chasmosaurus lived in North America.
- Chasmosaurus was a herbivore (plant-eater).
- Chasmosaurus was about 16 to 20 feet (5 to 6 meters) long.

Click Here | Product Description:
The horned dinosaurs, a group of rhinoceros-like creatures that lived 100 to 65 million years ago, included one of the greatest and most popular dinosaurs studied today: Triceratops. Noted for his flamboyant appearance--marked by a striking array of horns over the nose and eyes, a long bony frill at the back of the head, and an assortment of lumps and bumps for attracting females--this herbivore displayed remarkable strength in its ability to fight off Tyrannosaurus rex. It was also among the last dinosaurs to walk the earth. In telling us about Triceratops and its relatives, the Ceratopsia, Peter Dodson here re-creates the sense of adventure enjoyed by so many scientists who have studied them since their discovery in the mid-nineteenth century. From the badlands of the Red Deer River in Alberta to the Gobi Desert, Dodson pieces together fossil evidence to describe the ceratopsians themselves--their anatomy, biology, and geography--and he evokes the human dimension of their discovery and interpretation. An authoritative survey filled with many original illustrations, this book is the first comprehensive presentation of horned dinosaurs for the general reader. Dodson explains first the fascinating ways in which the ceratopsians dealt with their dangerous environment. There follows a lesson on ceratopsian bone structure, which enables the reader quickly to grasp the questions that still puzzle scientists, concerning features such as posture, gait, footprints, and diet. Dodson evenhandedly discusses controversies that continue, for example, over sexual dimorphism and the causes of the dinosaurs' disappearance. Throughout his narrative, we are reminded that dinosaur study is a human enterprise. We meet the scientists who charmed New York high society into financing expeditions to Mongolia, home of Triceratops' predecessors, as well as those who used their poker winnings to sustain paleontology expeditions. Rich in fossil lore and in tales of adventure, the world of the Ceratopsia is presented here for specialists and general readers alike. |

World-renowned dinosaur illustrator and researcher Gregory Paul provides comprehensive visual and textual coverage of the great Mesozoic animals that gave rise to the living dinosaurs, the birds.
