Stratigraphic frame work of the type locality of Pirro Nord Mammal Faunal Unit (Late Villafranchian, Apricena south-eastern Italy)
2013
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…

The post-Miocene marine succession of the «Apricena horst» is described with the purpose to verify the chronostratigraphic constraints for the type-locality of the Pirro Nord Faunal Unit. The stratigraphic succession has been subdivided in four units bounded by ubiquitous unconformities with evidence of subaerial exposure. The two basal units (dated late Zanclean to at most early Piacenzian) are formally grouped in the Lago di Varano Fm. that on the whole consists of sediments ranging from lagoonal to circalittoral environments. Within the lowermost unit, a megabreccia is interpreted as the product of a tsunami event. The third unit, Gelasian in age, is informally cited as Calcari a Briozoi…
