Arcoida (Mollusca, Bivalvia) del Plioceno de la provincia de Málaga, España

Abstract

Arcoida (Mollusca, Bivalvia) from the Pliocene of Málaga (Spain)

In this work we show the results of a taxonomic study of the order Arcoida (Mollusca, Bivalvia) found in the numerous fossiliferous outcrops from the marine Pliocene sediments of Málaga province (Southern Spain), in which the preservational state of the fossils is excellent. 19 species of arcoids are identified: Arca (Arca) noae Linné, A. (A.) tetragona Poli, Barbatia (Barbatia) barbata (Linné), B. (B) empolensis Micheli et Tone, B. (B.) modioloides (Cantraine), B. (B.) mytiloides (Brocchi), B. (Acar) clathrata (Defrance), Anadara (Anadara) diluvii (Lamarck), A. (A.) pectinata (Brocchi), Bathyarca sp., Striarca (S.) lactea (Linné), Limopsis (Limopsis) aurita (Brocchi), L. (Pectunculina) anomala cancellata Michelotti, L. (P.) aradassi (Testa), Glycymeris (Glycymeris) glycymeris (Linné), G. (G) bimaculata bimaculata (Poli), G. (G.) insubrica (Brocchi) y G. (G.) inflata (Brocchi). A brief guide to differentiate them is offered.
