Birds Are Living Dinosaurs — Descendants of Theropods
Modern birds are not merely dinosaur relatives — they ARE dinosaurs. They evolved from a group of two-legged theropod dinosaurs called maniraptorans during the Late Jurassic period, around 150 million years ago. Fossils like Archaeopteryx and Microraptor show clear transitional features. Today's ~10,000 bird species make dinosaurs the most species-rich group of land vertebrates on Earth.
