Introduction

The Upper Perigordian quarry of Corbiac is in the Central Perigord region of southwestern France near the town of Bergerac (LaVille, Rigaud & Sackett 1980, fig. 6.2). Excavations at the site were directed by François Bordes from 1962 to 1967 (Bordes 1968). The upper stratum (Level 1) yielded an estimated 100,000 blades, over 1,000 cores in various stages of reduction, and approximately 10,000 finished tools (Bordes & Crabtree 1969, 1). Based on the abundance of microgravettes, Gravettian points, and dihedral burins, Bordes judged the Level 1 assemblage to be transitional between Perigordian VI and proto-Magdalenian, and suggested a relative date of c. 20,000 b.c. for it. He called the assemblage Evolved Perigordian, because it exhibited Upper Perigordian and proto-Magdalenian traits. This assemblage had an important role in the argument that was advanced that the latter industry was the terminal phase of Perigordian development (Bordes & De Sonneville-Bordes 1966; LaVille, Rigaud & Sackett 1980).
