Most people are not that interested in the prehistoric ocean. If you read books you will learn more about prehistoric ocean. Most people don't have a collection of prehistoric fossils. There are ammonite shells and shark teeth. There are megaladon teeth. Some animals are ammonites, tylosaursus , and megaladon. A megladon is a shark that went extinct 20 million years ago. An ammonite is a squid like creature that lived in a spiral shell. A tylosaursus is like a monster! It was the biggest thing in the ocean at the time! They ate everything, even each other!
