Title Of Article :
Turonian gastropods from the Coastal Basin of Gabon: Gabon store section, South of Libreville
Abstract :
The taxonomy and palaeoecology of the Turonian gastropods fauna from the geological section ‘Gabon Store’ (southern Libreville, Gabon) are discussed. Seven taxa are recognized: Armenocerithium haidingeri (Zekeli), Cerithium sp. A, Cerithium sp. B, Cerithium sp. C, Nerinea sp., Pseudamaura sp. and Turritella sp. Two genera Armenocerithium anda Nerinea are reported from the Gabonese coastal basin for the first time. The association of macrobenthic fauna (gastropods and bivalves) indicates: (1) a medium water energy level and (2) a stable and soft substrate during Turonian deposit of the ‘Gabon store’ section.
