RESUMO

In a new study, LeBlanc and co-workers have discovered an unusually complex dentition in a fossil relative of the modern-day tuatara that features compound occlusal surfaces, thick and prismatic enamel, and a novel enamel-to-bone tooth attachment. This finding suggests that complex dentitions arose independently in several reptilian lineages.
