1" Juvenile Camarasaurus Tooth On Sandstone - Colorado

This is a 1" long tooth of Camarasaurus, a giant sauropod dinosaur from the Morrison Formation. It had very distinctive teeth that were designed for eating coarse vegetation. Given the relatively small size of this tooth is would have come from a juvenile. It displays some nice feeding wear and was left partially embedded in the sandstone it was found in creating a nice display base. There is one repaired crack with a small amount of gap fill restoration running through the center of the tooth.

This tooth was collected this past summer from our partners private quarry East of Dinosaur, Colorado.

Camarasaurus was a medium-sized sauropod dinosaur whose fossils are found in the Morrison Formation of the Southest United States. It is estimated to have reached lengths of up to 75 feet long and had an estimated maximum weight of around 50 tons. Compared to contemporary Diplodocids, it had a shorter tail, longer forelimbs, and a much larger and more robust skull.

Camarasaurus skulls are quite distinctive: they have blunt snout and quite a square shape. Camarasaurus had large, spoon-shaped teeth, unlike many sauropod dinosaurs that had small, peg-like teeth. This likely indicates that it ate coarser vegetation, allowing it to share the same environment as other sauropods without competing for food. It may have replaced its teeth approximately every 60 days as they became worn from chewing. Its cervical vertebrae had hollow chambers to reduce weight on the neck, leading to its name, which means “chambered lizard”.

Camarasaurus is considered the most abundant of the sauropod dinosaurs found in North America. Its fossils have been found in almost every major Morrison Formation dinosaur locality, with fossils found in localities from across many states including New Mexico, Utah, Colorado, Montana and Oklahoma.
