👉 Tropidoderidae is a family of extinct, large-toothed lizards from the Late Cretaceous period in Europe and Asia. These reptiles were known for their distinctive beaks that could be used to crack open tough plant material, such as mosses and lichens, which they fed on. They lived during the late Cretaceous Period (68 to 59 million years ago), roughly 12 million years after the Cambrian period.
