Fertile Crescent: Europe: Africa: Siberia: The Acheulo-Yabrudian complex is a complex of archaeological cultures in the Levant at the end of the Lower Palaeolithic.
It is also called the Mugharan Tradition[1] or the Acheulo-Yabrudian Cultural Complex (AYCC).
The Yabrudian tradition is dominated by thick scrapers shaped by steep Quina retouch; the Acheuleo-Yabrudian contains Yabrudian scrapers and handaxes; and the Pre-Aurignacian/Amudian is dominated by blades and blade-tools.
[3] Determining the age period for the Acheulo-Yabrudian has been difficult as its major excavations occurred in the 1930s and 1950s, before modern radiometric dating.
This would make the Lower–Middle Palaeolithic transition rapid occurring at 215,000 BP within a 30,000 year period.
