MOLLUSK SPECIES AT A PLIOCENE SHELF WHALE FALL (ORCIANO PISANO, TUSCANY)
The recovery of an intact, 10 m long fossil baleen whale from the Pliocene of Tuscany (Italy) offers the first opportunity to study the paleoecology of a fully developed, natural whale-fall community at outer shelf depth. Quantitative data on mollusk species from the whale fall have been compared wi...
