Stratigraphic frame work of the type locality of Pirro Nord Mammal Faunal Unit (Late Villafranchian, Apricena south-eastern Italy)

The fossiliferous karst deposits of the typical Pirro Nord Faunal Unit recently revived interest for the lithic tools documenting the human occurrence in southern Italy at Early Pleistocene. Therefore, a revision of the Pliocene to lowermost Pleistocene stratigraphic succession was needed. It was carried on with a twofold aim: to detail the stratigraphic architecture and the structural-depositional evolution of the “Apricena horst”, and to verify the chronostratigraphic constraints for the Pirro Nord F.U. in the type area of Apricena. The stratigraphic record has been subdivided in four units bounded by ubiquitous unconformity surfaces, often associated to evidence of sub-aerial exposure. F…
