How can you tell a fossil egg?
Genuine fossil eggs usually have an easily identifiable shell which differs significantly from the enclosed sediments either by having a fine surface ornamentation (the smoother the “shell,” the less likely it is to be a non-bird dinosaur egg) or a specific type of crystalline structure in cross-section.
