High-resolution microscopic images of the surface of dental enamel of lepidosauria, which is a subclass of reptile including monitor lizards, iguanas, lizards and tuatara, allow scientists to determine their dietary habits. The enamel wear patterns reveal significant differences between carnivores and herbivores, but also allow finer distinctions, such as between algae-, fruit-, and mollusk-eating species. These findings are the result of research by a team led by scientists at Johannes Gutenberg University Mainz (JGU). They point out that it has hitherto been difficult to make such fine distinctions between dietary behavior on the basis of dental or skeletal remains alone, particularly in the case of extinct species, because in many reptiles the teeth are of similar shape.
