    Systematic revision of the Eocene sharks (Chondrichthyes) from Bolca Lagerstätte, Italy

    (FWF-Project M 2368)


    Primary Investigator: Dr. Giuseppe Marramà

    Goals

    The goal of the project is to review the systematics of the Eocene sharks from the Italian Bolca Lagerstätte, in order to interpret their palaeobiological, palaeoecological and biogeographic significance. Special attention will be paid to the detailed anatomical comparison with their living and extinct relatives. The Eocene (50 million years) Konservat-Lagerstätte of Bolca, in Italy, is one of the most famous palaeontological sites in the world. Although more than 100,000 fish specimens were collected from this deposit during the last four century and more than 230 taxa were erected, several aspects regarding the palaeobiodiversity and the evolutionary significance of several fish groups have been neglected or underestimated. In particular, Eocene sharks of Bolca lack of a modern perspective from a systematic and taxonomic point of view. This project will be therefore a contribution to the knowledge of one of the most famous and well-studied palaeontological sites of the world, in order to improve our understanding about the palaeoecology and palaeoenvironment of Bolca, also providing an evolutionary significance for their cartilaginous fishes, after the end-Cretaceous extinction.
