. Contribution du site paléon-tologique de Lissasfa (Casablanca, Maroc) à une nouvelle interprétation du Mio-Pliocène de la Méseta.. Comptes rendus de l'Académie des sciences. Série IIa, Sciences de la terre et des planètes, Elsevier, 1999, tome 329, pp.617-622. halshs-00004408 (Biberson, 1961;Stearns, 1978 (Coiffait-Martin, 1991) and Aïn Guettara in Eastern Morocco (Brandy & Jaeger, 1980). However, these latter sites contain several taxa of European origin (Stephanomys, Apodemus, Cricetus) that are missing at Lissasfa. This may be explained either by several migration events or, more probably, by a bio-geographic differentiation between the coastal plains and the hinterland. Lecointre, 1952, 1963and Gigout, 1956
