BALDANZA, Angela et al. The bathyal decapod crustacean community from the Poggio i Sodi quarries (Siena Basin, Tuscany, Italy). Bol. Soc. Geol. Mex [online]. 2013, vol.65, n.2, pp.335-353. ISSN 1405-3322.
A rich decapod fauna from the Early Pleistocene (late Gelasian-early Calabrian) of Poggio i Sodi quarries (Siena, Tuscany, central Italy) is here reported. Integrated biostratigraphical, sedimentological and paleoecological analyses have been carried out, and some paleoenvironmental inferences are also proposed. The studied decapod community is herein assigned to the upper bathyal; several paleoenvironmental factors (cool water conditions at the sea floor, clay soft bottom, nutrients, very low environmental energy and sedimentation rate) influenced and promoted the crustacean settlement.
