Dinosaurs

Dinosaurs were the only warm blooded reptiles. Some dinosaurs were nocturnal. The velociraptor was nocturnal. The biggest dinosaur egg was as big as a watermelon! Paleontologists are people who find the remains of the "terrible lizards." The word dinosaur means terrible lizard. Once a dinosaur dies, it turns into a skeleton then sand covers the skeleton. Meanwhile the sand becomes buried too. The skeleton turns to rock, then you have a fossilized dinosaur. Dinosaur footprints can become fossils. Dinosaurs have two cousins: one--sea dinosaurs and two--birds. Some dinosaurs are alive still--the birds. The birds took cover when the dinosaurs died.
