👉 Eupterotegaeus is a genus of extinct mammals from the Late Cretaceous period, located in Europe and Asia. These creatures were herbivores that lived during the late Cretaceous era (68-58 million years ago) before the emergence of the modern mammalian species. Eupterotegaeus are known for their unique anatomy, including a long neck with a bulbous jaw, which is similar to that of modern mammals and humans.
