| Abstract |
The Teleostean otolith fauna of the Marls of Saubrigues is considered to be one of the richest known. 82 species are recognised, representing 40 families. 14 new species are introduced: "genus aff. Lemkea" saubriguensis, "genus aff. Valenciennellus" kotthausi, Saurida rectilineata, Symbolophorus meridionalis, Diaphus cahuzaci, Diaphus poignantae, Adioryx ostialis, Myripristis verus, genus aff. Lepidotrigla” postdorsalis, "genus Triglidarum" parvulus, Neoscombrops flexosus, Dentex (Polysteganus) nolfi, Bembrops 'VandeVeldae and "genus Perciformorum" wheeleri. At least 16 species have persisted up to the present, or are very close to extant species. This deep neritic fauna, enrid1ed on one hand with littoral species, on the other hand with numerous mesopelagic fishes, resembles the extant fauna of the tropical and subtropical zones of the eastem Atlantic. The associations at the two sites sampled are obviously different, suggesting distinct stratigraphical levels, although their exact stratigraphical relationships couldn't be established. Both associations reflect deep neritic deposition, but a more precise interpretation can only be obtained by the examination of otolith associations from modern sea-floors with well known geographical and bathymetric locations.The deep neritic and mesopelagic components of the fauna will have little biostratigraphical value. On the contrary, the littoral component may acquire biostratigraphical significance, if compared with a biostratigraphical scale for littoral faunas, resulting from the study of otoliths of the underlying and overlying Aquitanian Miocene strata. |
