Camarasaurus
Click here for more Camarasaurus Pictures
Camarasaurus was a giant herbivore (plant-eater) that lived
in North America during the late Jurassic period,
about 155 to 145 million years ago.
Camarasaurus appears to have been very common during that period,
and may have roamed in herds over the tropical plains that covered North
America at that time.
Camarasaurus was about 59 feet (18 meters) long,
and probably weighed about 20 tons.
Polished pebbles are often found in the same rocks as
Camarasaurus fossils.
It is possible that Camarasaurus, just like many modern birds do, may have
swallowed rocks as an adding to grinding up tough plant food. It would then
have later regurgitate the stones (and replace them with new ones), once
the stones had been worn down, and were no longer useful as a digestive aid.
Fossilized
Camasaurus eggs have been found. These were arranged in lines, rather
than arranged in nest like some other dinosaur species',
and hence it is believed that like most other
Sauropods, that Camarasaurus
did not tend its young.
The first Camarasaurus
fossils
were discovered in
Colorado
in 1877 by
Oramel W. Lucas. Lucas sold the bones to
Edward D. Cope,
and named them in the same year.
The first full skeleton of Camasaurus was found in
1925
by Charles W. Gilmore. Although it was not realized at the time, this
specimen was a young animal, and hence many contemporary illustrations
show Camarasaurus much smaller than is now known to be the case.

Camarasaurus Facts
Here is a summary of some of the key facts about Camarasaurus:
- Camarasaurus was a genus of dinosaur.
- "Camarasaurus" means "chambered lizard" (referring to holes in its vertebrae). This name was chosen by Edward D. Cope in 1877.
- Camarasaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Camarasaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
- Camarasaurus was a Sauropod - a member of a group of related large quadrupedal herbivorous (plant-eating) dinosaur with long necks.
- Camarasaurus lived between about 155 million years ago and 145 million years ago, during the Jurassic period.
- Camarasaurus lived in North America.
- Camarasaurus was a herbivore (plant-eater).
- Camarasaurus is thought to have swallowed stones which would have been used to help grind up tough plant material (some modern birds do the same thing). Fossils of these stones ("gastroliths") have been found in the same rocks as Camarasaurus.
- Camarasaurus was about 59 feet (18 meters) long.
- Camarasaurus weighed about 20 tons.
