Explanation:

A fossil of an ancient shark in Kansas indicate that B. Kansas was once under water.

In prehistoric time, Kansas was covered by the ocean from the evidence of sea creatures found in Kansas rocks years later such as oysters, sharks, and other fishes. The lake was a natural habitat for most plants, sea birds, huge fishes, and other water reptiles.  

Some of the water animals found in Kansas in the Mesozoic era include the Tylosaurus which was a fish-like reptile that had a length of 40 feet. Due to its build and structure, it was deadly and very dangerous to the other sea animals.
