Physical appearance and biologyEdit
Metriorhynchus was a marine crocodile. Instead of possessing feet and claws, it had flippers. It had a streamlined body, with a few of the scaly lumps and bumps that modern crocodiles possess. Its tail was large and powerful, and would have propelled it gracefully through the water by the use of a strong, sideways-sweeping motion.
Behaviour and traitsEdit
Metriorhynchus was a very versatile predator that would hunt anything from ammonites to giant fish like Leedsichthys. They are also been known to hunt flying pterosaurs like Rhamphorhynchus. However, Metriorhynchus was at risk of being eaten itself by larger predators like Liopleurodon.
Metriorhynchus only came onto land to lay its eggs. It would drag itself onto land using its flippers like giant turtles. Immediately after laying its eggs, Metriorhynchus would return to the water. Its young would face the hazardous journey to the water when they were born.
A Metriorhynchus, as well as a Hybodus, repeatedly attacked a sick Leedsichthys and tore off lumps of its flesh. It then investigated Nigel Marven and attempted to nip him but he managed to knock it away.
