Ostracod associations coming from the Upper Triassic (Tropites subbullatus/Anatropites spinosus zones of the Tuvalian substage) clays and sandstones of the Mufara Formation outcropping along the west side of Monte Gambanera (Castel di Iudica, central-eastern Sicily) have been analysed for the first time. The specimens are relatively abundant, silicified, well preserved and often preserved as complete carapaces. Over 200 specimens have been determined. They belong to the families Healdiidae, Bairdiidae, Bythocyprididae, Acratiidae, Cytheruridae, Limnocytheridae, Candonidae, Cavellinidae, Polycopidae and Thaumatocyprididae. Thirty-seven species are identified of which nine species are new: Hungarella forelae n.sp., Hungarella siciliiensis n.sp., Bairdia andrecrasquini n.sp., Bairdia gambaneraensis n.sp., Ptychobairdia iudicaensis n.sp., Ptychobairdia leonardoi n.sp., Petasobairdia jeandercourti n.sp., Kerocythere dittainoensis n.sp. and Mockella barbroae n.sp.
Résumé
Pour la première fois est ici analysée une association d’ostracodes provenant du Trias supérieur (zones à Tropites subbullatus/Anatropites spinosus du sous étage Tuvalien) dans les argiles et grés de la Formation Mufara affleurant le flanc ouest du Mont Gambanera (Castel di ludica, Sicile Centre Est). Les spécimens, silicifiés, sont relativement abondants, bien préservés et les plus souvent retrouvés sous formes de carapaces complètes. Plus de 200 spécimens ont été identifiés. Ils appartiennent aux familles Healdiidae, Bairdiidae, Bythocyprididae, Acratiidae, Cytheruridae, Limnocytheridae, Candonidae, Cavellinidae, Polycopidae and Thaumatocyprididae. Trente-sept espèces sont reconnues dont sont nouvelles: Hungarella forelae n.sp., Hungarella siciliiensis n.sp., Bairdia andrecrasquini n.sp., Bairdia gambaneraensis n.sp., Ptychobairdia Iudicaensis n.sp., Ptychobairdia leonardoi n.sp., Petasobairdia jeandercourti n.sp., Kerocythere dittainoensis n.sp. and Mockella barbroae n.sp.
