This is a classic dromaeosaur "raptor" dinosaur tooth. It possesses a RARE IVORY WHITE enamel with a natural luster, and is from a large dromaeosaur! Most dromaeosaurs were only knee-high and about the size of small dogs, hence the very small teeth that are usually found.
Many African dinosaurs are yet undiscovered and/or identified. Saharan expeditions in the recent years have yielded incredible new discoveries of many species never known to exist including dromaeosaurs. There are likely several species of African dromaeosaurs, ranging from the size of a peacock up to the size of Velociraptor, that have never been attributed based on wide ranging characteristics of the teeth.
