摘要

Palaeoenvironmental distribution of Messinian oysters in the Sorbas Basin (Andalucia, SE Spain). According to their abundance in the Cainozoic deposits and their good preservation, the oysters constitute good indexes for the Neogene palaeoenvironmental reconstructions. So, in this paper, oysters are used to propose palaeoenvironmental reconstructions of the Sorbas Basin (Andalucia, SE Spain) during the Messinian, both before and during the deposit of evaporites. Four sections have been studied. The three first ones are located in the pre-evaporitic Messinian (La Mela, Cerro de Los Lobos and Cerro Mandras) and have provided four species of oysters: Neopycnodonte navicularis (Brocchi, 1814), Crassostrea gryphoides (Schlotheim, 1913), Ostrea lamellosa offreti Kilian, 1889, et Hyotissa hyotis (Linné, 1758). The sequential distribution of these species in the sections and the ecological affinities of Recent related species are used to propose a pattern of distribution of oysters during the Messinian in the western Mediterranean: (1) N. navicularis seems to be mainly a species of deep inner shelf and outer shelf (circalittoral sensu . (2) C. gryphoides et O. lamellosa offreti are distributed in the inner shelf (infralittoral sensu mainly on fine substrates for C. gryphoides and mainly on coarse substrate for O. lamellosa offreti (3) H. hyotis is restricted to shallow inner shelf and near the coral reefs.
