👉 Trogopterus is a genus of extinct mammals that lived during the Late Cretaceous period, approximately 68-65 million years ago. They were known for their large, powerful jaws and sharp teeth, which allowed them to consume large amounts of food efficiently. The specific term "trogopterus" was used by paleontologists to refer to these animals because they are often described as having a muscular structure reminiscent of the bones found in ancient creatures.
