More significantly, the scientists also recovered some fossilized skin of dinosaur embryos. This is the first time such a discovery has been made. These embryo fossils suggest answers to some questions regarding dinosaur reproduction and development.
Based on the massive clusters of eggs found in the region, it seems as if the hundreds of sauropods would gather together to lay eggs. Moreover, the find confirmed the fact that sauropods laid eggs, dispelling theories that they gave live birth to their offspring.
The fossils are between 70 and 90 million years old. The concensus among
geologists is that a flooding river buried the eggs; protective mud allowed
them to fossilize.

Sauropods, which according to the New York Times are "giant plant-eating
dinosaurs with long necks and tails, huge bodies and four elephant-shaped
legs." Hmmmm.... elephant-shaped legs.
