|Camarasaurus lentus skull.|
Camarasaurus (ca-mara-sawr-us) (meaning "chambered lizard") was a large plant-eating dinosaur. It was about 18 meters long and weighed about 18 metric tones. Its name comes from its skull, which is in the shape of an arch. It lived during the late Jurassic Period between 155 and 145 million years ago. These dinosaurs may have lived in herds.
There are four species of Camarasaurus:
- C. grandis ("grand chambered lizard")
- C. lentus
- C. lewisi
- C. supremus ("biggest chambered lizard")
