The Deep Past of the White Shark, , in the Mediterranean Sea: A Synthesis of Its Palaeobiology and Palaeoecology.

The white shark, , is the main top predator of the present-day Mediterranean Sea. The deep past of in the Mediterranean is witnessed by a rather conspicuous, mostly Pliocene fossil record. Here, we provide a synthesis of the palaeobiology and palaeoecology of the Mediterranean white sharks.

Polyplacophoran Feeding Traces on Mediterranean Pliocene Sirenian Bones: Insights on the Role of Grazing Bioeroders in Shallow-Marine Vertebrate Falls.

Chitons (Polyplacophora) include some of the most conspicuous bioeroders of the present-day shallow seas. Abundant palaeontological evidence for the feeding activity of ancient chitons is preserved in the form of radular traces that are usually found on invertebrate shells and hardgrounds. We report on widespread grazing traces occurring on partial skeletons of the extinct sirenian from the Lower Pliocene (Zanclean) of Arcille (Grosseto Province, Tuscany, Italy).
