👉 Xenomugil is a genus of extinct mammals from the Late Cretaceous period, which occurred approximately 79 million years ago. They were characterized by a small size and lacked a fully developed jawbone, suggesting they lived in an environment with limited food resources. The exact remains of Xenomugil are not known for certain, but their fossils have been found in various parts of the world, including North America, Europe, and Asia.
