Jurassic Morrison Camarasaurus Tooth
Camarasaurus sp.
Morrison Formation
Upper Jurassic
Moffat County, Colorado
This specimen is a very fine example of Camarasaurus. The tooth is 6 cm long and has excellent detailed texture of the enamel. The anterior side of the tooth shows the transition to the root. The tooth has a small wear facet indicating that it was fairly recently erupted. There is only one small area (1.5 cm x 0.5 cm) of restoration on the upper left side of the crown (view from the front). The other restoration is filling of tiny natural fractures. This is a very handsome and well preserved exemplar.

Camarasaurus was a genus of quadrupedal, herbivorous dinosaurs. It was the most common of the giant sauropods to be found in North America. Its fossil remains have been found in the Morrison Formation of Colorado and Utah, dating to the Late Jurassic epoch (Kimmeridgian to Tithonian stages), between 155 and 145 million years ago. Camarasaurus presented a distinctive cranial profile of a blunt snout and an arched skull that was remarkably square. It likely travelled in herds, or at least in family groups. The name means "chambered lizard", referring to the hollow chambers in its vertebrae.

Camarasaurus is among the most common and frequently well-preserved sauropod dinosaurs. The maximum size of the most common species, C. lentus, was about 15 meters (49 ft) in length. The largest species, C. supremus, reached a maximum length of 23 meters (75 ft) and maximum estimated weight of 47 tonnes (51.8 tons).
The arched skull of Camarasaurus was remarkably square and the blunt snout had many fenestrae, though it was sturdy and is frequently recovered in good condition by paleontologists. The 19 centimeter long (7.5 in) teeth were shaped like chisels (spatulate) and arranged evenly along the jaw. The strength of the teeth indicates that Camarasaurus probably ate coarser plant material than the slender-toothed diplodocids
