Despite stratigraphic incertainties, the samples sample of Pleistocene faunal remains Nicolăescu- should date from the earlier Upper Paleolithic of this portion of Plopşor, ; Daicoviciu et al. These dates Paleolithic archeological remains continue to therefore imply that the Pleistocene human occupation of the site consists of a relatively late Early Upper Paleolithic or pertain dating isotopic discussions dating isotopic the Paleolithic of Romania very early Middle Upper Paleolithic and a fairly late Middle especially of the Middle Paleolithic and the early Paleolithic.
