Theropoda is a group of bipedal dinosaurs known for their carnivorous diet. This clade includes well-known species such as Tyrannosaurus rex and Velociraptor. Theropods are characterized by their hollow bones, sharp teeth, and three-toed limbs, which helped them hunt and run efficiently. Interestingly, not all theropods were large and fearsome predators. Some, like Archaeopteryx, show features that link them to modern birds, indicating that birds are actually descendants of theropod dinosaurs. This connection highlights the evolutionary transition from dinosaurs to birds, showcasing the diversity within the Theropoda group.
