Do know that some eggs were as big and as round as a soccer ball.Others were long and oval.The eggshells were thick, and the egg surface was covered with tiny pits.No one knows how long it took for dinosaur eggs to hatch, but it was probably a few weeks.Curled up tightly inside its egg, a baby dinosaur is nearly ready to hatch.Soon it will push hard , and as the eggshell cracks, the baby will come into a new world.
