👉 Dremomys is a genus of extinct mammals that lived during the Late Cretaceous period, approximately 65 million years ago. This group of theropods was characterized by large size and a single skull with multiple incisors (teeth). The exact evolutionary relationships between Dremomys and other members of its clade are not well-established, but it is believed to have been a terrestrial predator that likely lived in the forests of North America.
