They had a hypothesis that the eggs belonged to sauropods.

5. What types of rocks were the paleontologists looking for?
They were looking for sandstone and mudstone deposited 70-90 million years ago.

6. What types of things did the paleontologists know for sure about the egg fragments they discovered?
Some of the eggs had embryonic dinosaur embryos inside, fragments of scales were fossilized, and the eggs were buried in mud.

7. What questions did the scientists have about the eggs?
What caused the death of these dinosaur eggs? Were these really the eggs of sauropods? What did the embryos look like? Were the eggs laid in nests? Did dinosaurs return to the site after laying the eggs? What other dinosaurs lived at the site? Did the dinosaurs live in herds?
