It is traditionally assumed that last of the dinosaurs became extinct 65.5 million years ago in the K-T Extinction Event. Birds and birds alone are the direct decedents of dinosaurs. Other species commonly associated with dinosaurs such as the crocodilians evolved from more ancient ancestors of dinosaurs the archosaurs. Dinosaurs evolved after the crocodilians had already split of onto another branch of the evolutionary tree. There is however growing support based on the fossil record that birds not only directly evolved from dinosaurs but are so similar in morphology that they are in fact dinosaurs in their own right.
What kinds of organisms survived the mass extinction that killed the dinosaursWhat kinds of organisms survived the mass extinction that killed the dinosaursWhat kinds of organisms survived the mass ex?
Cretaceous-Paleogene extinction event was one of the most important events in Earth history. When a massive asteroid fell on the coast of Yucatan in modern Mexico it eradicated about half of all animal species, including the dinosaurs. But many of other organisms, such birds, survived.
