During the developing of the skeleton of the Pliosaur there were found near the roof of its mouth ribs of a large reptile, and in the region of its stomach remains of a large fish and a large number of hooks from the arms of decapods, and also small (3–4 mm.) gastroliths. In the region of the posterior part of the body there were found several Crustaceans (Glyphea) and a large number of Cypridina. Moreover, on the surface of the concretions encasing the skeleton there was a membrane (up to 1 cm thick) of a black, retinous substance, presumably a product of the decomposition of the corpse of tie Pliosaur. The cephalopod hooks and the fish remains signify that these animals served as food for the PIiosaur.

The Lower Volgen Sea, in which dwelt the Pliosaurs and Ichtyosaurs in contrast to the biassie bay of Holzmaden, was a normally saline busin with a normal gas regime. It was rather shallow, on its bottom a rich flora developed, giving rise to the bituminous shale, and a rich fauna dwelt in its waters.
