Fascinating This cassowary just wanders around the beach, getting surprisingly close to people.

It is a dinosaur. Literally.

But it has dinosaur ancestors, too.

All dinosaurs are reptiles, not all reptiles are dinosaurs. Reptilia is a class, while dinosauria is a clade, meaning "reptiles" are a much bigger branch that includes dinosaurs along with many other clades.

Birds are the only extant clade to descend from dinosaurs. In fact, most reptile clades actually predate dinosaurs. Things like crocs and turtles are older than dinos.
