Subsequent work has radically changed this situation and, where the Solutrean is concerned, established that its culture-stratigraphy sequence accords well with the traditional subdivision systematized for France by Ph. Smith, based on the successive appearance of different index fossils. Where lithic point typology suggests a break, this is confirmed independently by accompanying changes in the basic technology of blade production. In some cases, the existence of a given unit of the subdivision can only be inferred from the identification of the ...
