Large Cretaceous Crocodile Tooth

Description: This is a fine example of a tooth from a crocodyliform thought to be Sarcosuchus. Sarcosuchus is not a crocodile, but a relation. The genus was named by Paul Sereno from material discovered in Niger. This 13 meter long monster was thought to have included dinosaurs on its menu. Notice the good preservation of the enamel, making for a wonderful example of this rarely-seen Archosaur.. In order to keep their teeth fully functional, they were frequently replaced, with the new tooth pushing the old out as it grew. This is why teeth are the most commonly seen reptile fossil.
