Complex lizard teeth with multiple tips ("cusps")

Caption

3D reconstruction of the skull of an Amazon racerunner (Ameiva ameiva) captured through an X-ray micro-CT scan. Complex teeth with multiple tips ("cusps") are visible on the jaws. This feature—also seen in the dentition of early mammals—evolved many times in independent lizard groups.
