This is a FINEST GRADE tooth from a yet to be identified sauropod dinosaur of North Africa, most likely from a Titanosaur based on known discoveries and the comparison of this tooth to other Titanosaurs. Amazingly, this tooth is unbroken and complete with a hollow base which is so rare from this herbivorous dinosaur! The tip has no feeding wear indicating this tooth probably came from the sides of the jaws. These long rod-shaped teeth were ideal for the dinosaur to easily strip leaves and other vegetation off of branches like a rake, for efficient feeding.
Sauropod fossil dinosaur teeth are rarely discovered in the same fine condition as theropod teeth. Feeding on plant material rather than other struggling dinosaurs, the teeth of herbivorous sauropods were not designed to take punishment like meat-eating dinosaur teeth so their structure is not as durable. The long, peg-like shape of sauropod dinosaur teeth make them vulnerable to damage over time and easy to break apart over millions of years. What this translates to is that plant-eating sauropod dinosaur teeth are seldom found preserved as well as meat-eating dinosaur teeth. Sauropod dinosaur teeth of equal quality, compared to those from a carnivorous dinosaur, are more rare and their absence from the market demonstrates that.
