Dinosaur Eggs

Birds today hatch from eggs. Long ago, dinosaurs also hatched from eggs!

Female dinosaurs laid eggs. They always laid more than one egg at a time. Some of them laid more than 20 eggs at once!

Dinosaurs kept their eggs warm and safe. They made a nest for their eggs. Some buried their nest in the ground.

Some dinosaur eggs were large, and some dinosaur eggs were very small. Eggs were round or oval-shaped. Some eggs had hard shells, and some eggs had soft shells.

Inside the eggs, baby dinosaurs grew. Baby dinosaurs could breathe inside the eggs. They stayed in their eggs for 3 to 6 months.

Then, the babies would break through the egg!
