👉 Tyrannosaurs were a group of prehistoric birds that lived in North America during the late Cretaceous period, around 68-65 million years ago. They were characterized by their large size and robust wings, which allowed them to soar on the winds and fly great distances without needing to land. Tyrannosaurs were also known for their sharp teeth and powerful jaws, which they used to hunt prey such as smaller birds, reptiles, and even small mammals.
