Kimmerosaurus

Kimmerosaurus is a genus of plesiosaur that lived in Europe during the Late Jurassic period.

Fight for Life
In the beginning of the fourth episode, a hungry pod of Kimmerosaurus is seen hunting by ploughing their snouts into the sand, disturbing and chasing fish, crabs, shells, stones and Squatina, a genus of angel shark. When a Pliosaurus funkei appeared, the Kimmerosaurus head for the shallow water lagoons, where their enemy's bulk becomes a hindrance for it. Then, the Pliosaurus returns, getting into the lagoon by the rising tide. However, its bulk turns against it, and it is unable to catch any of the plesiosaurs. Later, a single Kimmersaurus is hunting near the surface. The pliosaur rushes up from below, like a shark, and stuns the plesisaur. The Pliosaurus then rips away one of the rear paddles. Just as the nursery is in sight, the Kimmerosaurus heads for it, but before it does so, the Pliosaurus rushes up, bursting out of the water with the cryptoclidid's neck trapped in its huge jaws. It bites through the neck, and grabs and eats the body in triumph. The Pliosaurus then leaves as the remaining half of the Kimmerosaurus sinks to the bottom of the sea.
