TOSCANO-GRANDE, Antonio et al. Neogene brachiopods from the southwestern Guadalquivir basin (south Spain). Rev. mex. cienc. geol [online]. 2010, vol.27, n.2, pp.254-263. ISSN 2007-2902.
This paper analyzes the first brachiopod record of three Neogene formations of the southwestern Guadalquivir Basin (Huelva province, SW Spain) with a wide cartographical distribution. Samples obtained in five sections of these formations have allowed to recognize three species belonging to the genera Terebratula, Maltaia and Cryptopora, the latter being the first record of this genus in Spain. In addition, the biostratigraphical distribution and palaeoecological context of these species and others present in upper Neogene sediments (Tortonian-Lower Pliocene) of south Spain are discussed.
