      As we showed in our thesis (Guadellli, 1987), the morphology of the pars petrosa is very distinctive but this cranial part is usually put aside by the archeozoologists. So in this text it seems interesting to us to compare the pars petrosa of the Reindeer and of the Red deer. Without giving a detailed account of morphology of this temporal part we can say as follows : The cranial part of the pars petrosa of the Reindeer draws an irregular picture. The medial side, very sinuous, is concave above the fossa cerebellaris ("fosse cérébelleuse") and convexe in his medio-ventral part. The ventral side of the pars petrosa of both species is triangular but the nervi trigemini print ("empreinte du nerf trijumeau") is more irregular in the case of the Reindeer. The aperture of the canalis facialis ("aqueduc de Fallope = orifice du nerf facial") of the Reindeer is broader than the one of the Red deer. The medial side of the pars petrosa of the Reindeer is concave while the one of the Red deer is straight. By the biometrical study of the faunal remains of Rangifer tarandus found at Combe-Grenal we show up some relevant dental size differences between the Reindeer of the layers 35 to 26 and those, more recent, of the layers 25 to 1. These differences seems to be absent on the post-cranial remains.

      L'étude biométrique des restes de Renne découverts à Combe-Grenal a permis de mettre en évidence quelques différences de taille significatives au niveau dentaire entre le Renne des couches 35 à 26 et ceux des couches 25 à 1 plus récentes. De telles différences ne semblent pas se manifester sur le squelette post-crânien.
