The Tyrannosauridae family includes some of the largest and most well-known carnivorous dinosaurs, such as Tyrannosaurus rex. These dinosaurs lived during the late Cretaceous period, around 68 to 66 million years ago. They were characterized by their massive skulls, powerful jaws, and strong hind limbs, which allowed them to be effective predators. Tyrannosaurids had small, yet strong, forelimbs with two fingers, which were likely used for grasping. Fossils of these dinosaurs have been found in North America and parts of Asia, providing valuable insights into their behavior and ecology. Their size and adaptations made them dominant predators of their time.
