Archosauria is a group of reptiles that includes crocodiles, alligators, birds, and their extinct relatives like dinosaurs. They are characterized by features such as teeth set in sockets and openings in the skull in front of the eyes. Think of it as a family tree π³ that connects seemingly different animals. Birds, surprisingly, are direct descendants of one line of dinosaurs. They showcase the incredible diversity that can evolve within a single group.
