It will detail tool types, chipping techniques, regional varieties, and outside influences. It will explore the extent to which Neanderthal man worked in gone and how the Mousterian flint forms are mirrored in this other medium. It will shoe how the Mousterian developed and how it was influenced by earlier and contemporary industries
