Today, birds are descendants of theropod dinosaurs. Theropods were a group of two-legged dinosaurs that included carnivores such as Tyrannosaurus Rex and Velociraptor, as well as herbivores such as Ornithomimus and Oviraptor.
Today's birds are thought to be descendants of theropod dinosaurs such as the velociraptor and the tyrannosaurus rex. Scientists have analyzed fossil evidence and found many similarities between the skeletal structure and DNA of these ancient dinosaurs and modern-day birds. This evolutionary link has helped shed light on the origins and development of avian species.
