👉 Exopterygota is a genus of extinct marine reptile from the Late Cretaceous period, around 139-121 million years ago. The name "exopterygota" comes from the Greek word for "sharp-tipped," which describes the sharp teeth on the jaws and claws of these creatures. This group was closely related to the extinct genus Acheilosaurus, but it is also considered to be a distinct species in its own right due to some similarities
