Researchers have securely dated a prehistoric human stone tool industry that is thought to have been used by early modern humans, or possibly late Neanderthals, around the time when early modern humans were beginning to emerge in Europe, arguably sometime between 40,000 to 50,000 years B.P...
The Uluzzian, a prehistoric stone tool techno-tradition represented by lithic artifacts unearthed by archaeologists at cave locations primarily in Italy and Greece, has been a central contender as a possible "transitional" industry between the typical stone tool types (the Mousterian) used by late European Neanderthals and those (Aurignacian, Châtelperronian) of the earliest modern human newcomers to Europe. Uncertainty and debate has historically characterized the exact chronology of the Uluzzian techno-complex, including the identification of the species of human that made and used them. Research within the past few years, buttressed by association of early modern human fossils found in context with Uluzzian tools, has strengthened the suggestion that they belonged to early modern humans.
Now, an international scientific team led by Katerina Douka of the University of Oxford is reporting the results of a new study, concluding that the Uluzzian arose or arrived in what is present-day Italy and Greece shortly before 45,000 years ago, with its latest phases placed at around 39,500 years ago, and "its end synchronous (if not slightly earlier) with the Campanian Ignimbrite eruption".
The Campanian Ignimbrite eruption refers to the eruption of the Archiflegreo volcano around 37,000 years B.P., coincidental or correlated to Middle Paleolithic (beginning 300,000 years ago) to Upper Paleolithic (beginning between 50,000 and 40,000 years ago) cultural transitions and the theorized replacement of Neanderthal populations by anatomically modern humans in southeastern Europe. The replacement theory and the Archiflegreo volcanic eruption as a causal element within this model has been a subject of continuing debate.

BP, in geology and archeology has many possible meanings. There is much confusion. Which is fine with me, since everyone knows exactly what B.C. means. Hopeful BP will die a natural death.
Hi, BP means “before present”, which is due to this being a radiocarbon date, which also means that “present” uses 1950 for its baseline.
