Abstract

The « Marnes et calcaires lumachelles à huîtres » Formation (late Albian–early Cenomanian) of the South Riffian Ridges, rich in bivalves, yielded in levels of upper Albian some gastropod specimens including: Ampullina aff. uchauxiensis Cossmann, Ampullina indet., Aporrhaidae indet., Calliomphalus cf. orientalis (Douvillé), Cerithioidea indet., Mrhilaia indet.,?Neogastropoda indet., Pleurotomaria indet., Pseudamaura subbulbiformis (d'Orbigny), Tylostoma aff. globosum Sharpe, and a rare bivalve, Pinna (Pinna) cretacea cretacea (Schlotheim). The two underlying formations « Conglomérat et marnes sableuses » and « Calcaires gréseux » (early to middle Albian?), poor in macrofauna, yielded rare Nerineopsis aff. excavata (Brongniart) and Turritella indet. These species are reported for the first time in the Moroccan Cretaceous deposits. © 2017 Elsevier Masson SAS
