MARA GARCIA, Edith Xio et al. The lower Pliocene lamniform sharks (Chondrichthyes, Galeomorphii) from the Arenas de Huelva Formation, southwestern Guadalquivir basin, Spain. Rev. mex. cienc. geol [online]. 2009, vol.26, n.3, pp.674-686. ISSN 2007-2902.
Lamniform teeth from eight localities of the lower Pliocene Arenas de Huelva Formation were studied in the southwestern part of the Guadalquivir basin. The genera Carcharias, Alopias, Isurus, Carcharocles and Parotodus were recognized. Carcharias taurus remains prevail, the other taxons being scarce. The selachian assemblage points out to littoral-neritic, subtropical to temperate environments.
