Name:    Dendroolithus (Hadrosaur Egg)
Age:  Cretaceous
Formation:  Kaoguo Formation
Location:  Xixia Basin, Henan Province, China
Size:  Egg is about 6 inches across!

This dinosaur egg is from a hadrosaur-type dinosaur (duckbill). Most hadrosaurs laid their eggs in nests of a dozen or more eggs. Usually, hatching and scavenging damaged the nests, obliterating any trace of the eggs that remained. Occasionally, some eggs survived predators and the elements, and eventually became fossils. Because of their delicate nature, intact eggs are very rare in the fossil record. Dinosaur eggs that retain their original shape and eggshell are some of the most collectible fossils in the world.

This specimen was imported legally many years ago. This fabulous Dendroolithus egg has been microscopically-prepared with an air-abrasive machine in the EXTINCTIONS Preparation Lab to reveal the fine detail of the eggshell. The eggshell covers almost all of the surface of the egg - WOW! (see close-up photos for detail) The egg is very inflated and sits on a nice, natural pedestal of matrix. The overall ''egg'' shape is quite nice, and the entire fossil simply displays beautifully. This is an extremely collectible example of a REAL Hadrosaur dinosaur egg from the Cretaceous of China.
