This unique, Museum-quality Mesosaurus tooth is genuine, completely intact with no repairs and in pristine condition. This incredible specimen includes a display box for preservation and display purposes. Mesosaurus (meaning "middle lizard") is an extinct genus of reptile from the Early Permian of southern Africa and South America. Along with it, the genera Brazilosaurus and Stereosternum, it is a member of the family Mesosauridae and the order Mesosauria. Mesosaurus was long thought to have been one of the first marine reptiles, although new data suggests that at least those of Uruguay inhabited a hypersaline water body, rather than a typical marine environment.Weight: 57 grams, Dimensions: 1 x .75 x 4.75 inches
