Camarasaurus was a long-necked (sauropodmorph) dinosaur that lived during the Jurassic age. Camarasaurus reached lengths of 60 feet (18 m) and weighed up to 18 tons (16 tonnes)! One end of this ‘teething bone’ has been completely removed by predation, probably a feeding or teething Allosaurus.

Camarasaurus and Allosaurus lived in North America at the same time, and it is thought that Allosaurus included Camarasaurus in its diet. This tibia demonstrates predator behavior in the savage world of the Jurassic and is the perfect addition to any predator vs. prey, or other teaching exhibit. It demonstrates not only the size of the animal, but also gives us a visual clue regarding the behavior of these distant giants from the past.
