Oviraptorid Embryo

Fossils of dinosaur eggs rarely have bones inside them. In 1993, however, Museum scientists found an egg in the Gobi Desert that contained the remains of a tiny dinosaur embryo from 80 million years ago. Like most scientific discoveries, this one raises as many questions as it answers.

Preparation: fossil in matrix
Locality Found: Ukhaa Tolgod, Mongolia
Date Collected: July 1993
Expedition Name: Gobi Expedition
Size: uncurled, the embryo would measure about 8 inches (20 centimeters) in length
Condition: well preserved, but missing tail and hindlimbs
