The Sponge genus Astraeospongium is present, preserved with solid skeleton and as isolated spicules, in Lower Devonian beds of Montagne Noire (Southern France). Isolated spicules are also present in the Central Morocco Lower Devon. The repartition of that genus in the Lower Devon out of North America is therefore larger than it was believed.Découverte dans le Dévonien inférieur de la Montagne Noire du Spongiaire Astraeospongium, sous forme d'exemplaires complets ou de spicules isolés. De tels spicules, déjà connus en Europe Moyenne, sont également présents dans le Dévonien inférieur du Maroc Central. L'extension de ce genre hors de l'Amérique du Nord, et dans le Dévonien inférieur, est donc plus grande qu'on ne le croyait.Termier Henri, Ter...
