This Mousterian facies is defined by numerous small bifaces (average size:~ 6-8cm) and bifacial scrapers, and is constitutive for the Middle Palaeolithic of the Bretagne and the Basse Normandie. Originally dated to the beginning of the last glacial (OIS5), some sites seem to be now securely dated to OIS3.
Important findings were made since the second half of the 19th century in the Eure Valley (Saint-Julien de la Liègue, Saint-Nicolas d’Attez “La Madeleine”), the Calvados region (Bons-Tassilly “Le Châtelet”) and at several sites in the Orne Valley (near Putanges-Pont Ecrepin, Saint-Brice-sous-Rânes, la “Bruyère”). Some of the sites are considerably large. For example Saint-Brice-sous-Rânes, la “Bruyère”9 covers serval hundred hectares. Many of these sites have a work-shop character (http://www.aggsbach.de/2011/10/bifacial-tools-from-saint-brice-sous-ranes/).
Bifacial tools display a cordiform, subcordiform and somtimes ovalaire character. The scrapers usually have a covering retouch at one side and often show an incomplete covering of the other side. Basal thinning of transverse scrapers is common. Many “unifaces” have similarities to the “Halbkeile” and many flat handaxes are “Faustkeilblätter” in the German nomenclature. Similar findings from what is now Germany are known from the Lichtenberg Micoquian site in the North European Plain in lower Saxony: http://kulturerbe.niedersachsen.de/viewer/objekt/isil_DE-MUS-163517_NLMH_AR_49521_494825/6/#topDocAnchor.
An exhibition in 1996 in Göttingen assembled findings from Lichtenberg and Eastern Micoquian sites, especially from Volgograd [Sukhaja Metchetka].
