 Bifaces are found both with and without a cortex, along with grattoir de cote, triangular flakes, tortoise cores, discoid cores and steep scrapers.This presented particular problems with sites where Heavy Neolithic material was mixed with that from the Lower Paleolithic and Middle Paleolithic, such as at Mejdel Anjar I and Dakoue.Although tools similar to Heavy Neolithic ones were found at later Neolithic surfaces sites, little relationship could be established between those found at the later Neolithic tells, where flints were often sparse, especially at those of later dates.
