[1] It was preceded by the Middle Paleolithic Mousterian culture, directly overlying it without an intervening bladelet industry.
[1] Radiocarbon dates suggest that this was one of the earliest Upper Paleolithic complexes, beginning perhaps as early as 36,000 BC.
Evidence found in the Yafteh cave assemblages, revealed that the early phase of this culture was not as sophisticated as the evolved middle phase, and it produced blades and bladelets using soft hammer from single platform prismatic cores with plain platforms.
This is also the case regarding the issue of whether this culture gradually evolved from the previous Zagros Mousterian cultural group, which is associated primarily with the Neanderthals, or whether early modern humans brought to the Zagros region the technologies linked to the Baradostian.
[citation needed] Perhaps precipitated by the most recent cold phase (the Würm glaciation) of the current ice age, the Baradostian was replaced by a local Epipaleolithic industry called the Zarzian culture.
