Question

Spring break had arrived, and Carol's family went camping along the river, seen here. During their stay, the family dug for fossils. Carol's father found pieces of elk skull and the bones of some other unidentified animals. Carol found an insect encased in amber, and her little brother found three fossilized shark's teeth.

Based on the family's fossil evidence, what can we hypothesize about the past history of the campsite?

B. It was once underwater.

Reason: fossil shark teeth indicate a marine environment in the past. The elk bones and insect in amber show later terrestrial/forest conditions, so the site experienced different environments over geologic time — including being underwater.
