Dinosaur Egg - Identification

Identification

Fossil dinosaur eggshell fragments can be recognized as such based three important traits. Their thickness should be roughly uniform, they are usually slightly curved, and their surface is covered in tiny pores. Less frequently, the concave underside of the eggshell fragment will preserve bumps known as mammillae. Sometimes the embryo had absorbed so much of the calcium that the mammilae need a magnifying glass or microscope to be seen. However, there are many kinds of naturally occurring objects which can resemble fossil eggs. These can fooled even professional paleontologists.
