Ornitopod Eggs

Spherical eggs discovered at nesting sites in Asia and North America once belonged to bipedal plant-eating dinosaurs known as ornithopods. Hadrosaurs (duck-billed dinosaurs) are probably the most widely recognised ornithopods.
Eggs from China and hadrosaur hatchlings found in the U.S. and Canada offer new clues about the nesting behaviour of these dinosaurs. Were ornithopod hatchlings altricial–helpless babies needing parental care, or were some precocious–ready to run from the nest and take care of themselves?
