As far as scientists know, all dinosaurs hatched out of eggs
(like all reptiles). Many types of dinosaur eggs have been found,
with shells that look very different from each other and also in many
shapes. Some of the eggs were huge - almost as large as
footballs. Others, perfectly round, such as the eggs from Titanosauridae, were the size of a bowling ball.
Scientists classify eggs by the type of eggshell. Once embryonic
skeleton material has been discovered in any type of egg, paleontologists
can then compare these small bones with an identified adult species. This,
is many cases, has led to a positive identification of the species of
dinosaur that hatched from that egg.
As of 2009, eight families, 13 genera and 37 species of dinosaurs eggs
have been distinguished from the Henan Province of China. Although the
parent species of all of these eggs is unclear at this time, future
discoveries will continue to uncover information to add to our dinosaur
