This is a Rebbachisaurus sp. tooth from the Baharja Formation, Kem Kem Basin in Morocco.
Rebbachisaurus was a large-bodied, small-headed, whip-tailed Sauropod who ate plants. The dinosaur lived during the Early Cretaceous, about 99 million years ago.
The tooth is peg-shaped, typical of a vegetable-eater, with most of the enamel still present and a root. The tooth measures 1.44 inches long and 0.33 inches wide at the base. The tooth has not been repaired.
