Utuntu dushimishije

1

Plotosaurus had a streamlined body and narrow flippers, making it look a bit like a modern dolphin or an ichthyosaur.1

2

Some of its tail vertebrae were fused together, which helped it swim more efficiently.1

3

It had large eyes, so it probably had excellent vision for spotting prey.1

4

Plotosaurus was one of the most advanced mosasaurs, with the highest level of aquatic adaptations in its family.1

5

Fossils of Plotosaurus have been found in Japan, suggesting it lived in the Pacific Ocean on both sides.2

6

The first fossils were discovered by a high school student named Allan Bennison in California in 1936.1

Plotosaurus was first named Kolposaurus in 1942 by paleontologist Charles Lewis Camp, but he changed it to Plotosaurus in 1951 because the name was already taken. The fossils were found in California by a student and others.1

Scientists are not sure if Plotosaurus lived only in North America or also in other parts of the Pacific, because some fossils from Japan and Chile might belong to this genus.12
