moustierian

from The Century Dictionary.

• Of or pertaining to Moustier, in France: a term used in the classification of Paleolithic human relics according to their workmanship and degree of finish, and applied to such as have the character of the flint scrapers found in the sands of Moustier. They are regarded as intermediate in workmanship between the ruder Acheulian and the more deftly made Solutrian implements, and it has hence been inferred that they belong to a correspondingly intermediate period.
