But modern plant-eating reptiles usually take a different route. A study published in Current Biology examined the complex and unique teeth of a 95-million-year-old plant-eating reptile, Priosphenodon avelesi. Where most plant-eating reptiles have relatively simple teeth that they can replace when worn down, Priosphenodon could not replace any of their teeth. Looking inside the teeth of Priosphenodon revealed that these hardy reptiles had evolved some elegant solutions to the problem of tooth wear. Priosphenodon is the most abundant and one of the few plant-eating reptiles at La Buitrera.
