The Plesiosauria or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago.

2.The Bobbitt worm.

4.Dunkleosteus.

Dunkleosteus is an extinct genus of arthrodire placoderm fish that existed during the Late Devonian period, about 358–382 million years ago. The name Dunkleosteus combines the Greek ὀστέον, osteon, meaning “bone”, and Dunkie in honor of David.

5.Mosasaurus.

6.Livyatian melvelli.

Extrapolating from its 10-foot-long skull, paleontologists believe that Leviathan measured upwards of 50 feet from head to tail and weighed as much as 50 tons, about the same size as a modern sperm whale.
