What is a baby dinosaur called?

Dinosaurs are hatched from eggs, therefore new baby dinosaurs are called hatchlings, just like their reptile cousins the turtles and crocodiles. Young dinosaurs, beyond the hatchling stage, are referred to as juveniles.

Fossilized dinosaur eggs have been found all over the world and they come in a variety of sizes. The largest egg found was 19 inches long and shaped like a football. The smallest egg discovered was about the size and shape of a tennis ball. Dinosaurs laid clusters of eggs in nests they covered with plants. The plants both hid them from predators and kept the eggs warm.
