Checa A.G., Oloriz F., Tavera J.M. (1986) Last records of "Aspidoceras" in the Mediterranean. Acta Geologica Hungarica, 29(1):161-168.
Last records of Mediterranean "Aspidoceras" are interpreted in the light of a recent systematic revision of this group. Four species appear at Upper Tithonian-Berriasian, whose evolutive behaviour is interpreted in relation to Upper Kimmeridgian Lower Tithonian Mediterranean "Aspidoceras". Also, migratory events (perhaps interchange) of this fauna towards the Andean province may be supposed.
