This is a fossil tooth from a yet to be identified Titanosaur sauropod dinosaur of North Africa. It is dramatically different from the typical sauropod dinosaur teeth found in the formation with its more flattened, broader cross-sectional profile and wrinkled enamel. In the last 20 years of collecting from this deposit, we have seen less than 5 teeth of this unique type!
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.
