摘要

在Costa Bausa，沿着Torrente Mazzarino的左侧（布切里东北部，西西里岛东南部），海相砂被许多作者称为上新世，因为它们的地层位置和它们所包含的软体动物动物群，在中新世碳酸盐序列之上不整合地出现。本文对这些沙洲的介形类进行了分类，发现了新种，首次对有孔虫类进行了分析，并编制了软体动物分类表。甲壳类动物区系主要由浅海属的Aurila、Neonesidea、Bosquetina、Callistocythere、Carynocythereis、Cistacythereis、Cytherelloidea、Cytheretta、Costa、Graptocythere、Grinioneis、Loxoconcha、Mutilus、Caudites、Pontocythere、半ytherura、Tenedocythere、Urocythereis、Verrucocythereis和Xestoleberis等标本组成。其中，新发现的有孔虫有8种，分别为：大耳虫（Kroemmelbeinella） hiblaea n. sp、海耳虫（Aurila costabausaensis n. sp）、水耳虫（Aurila daphnidis n. sp）、mazzarinoensis n. sp、sanctiandreae n. sp、tendocythere forticostata n. sp、Cytheretta bucheriensis n. sp、Verrucocythereis verrucomurata n. sp。在浮游有孔虫中，只有Orbulina universa、O. suturalis、Trilobatus trilobus和T. sacullifer出现过。底栖有孔虫的群落特征为：圆叶Amphistegina loifera、A. lessonii、Elphidium crispum、E. macellum、amcarii、A. parkinsoniana、Lobatula Lobatula、canris auricula、Patellina walgata、Quinqueloculina semulum、masilina oblonga、Oolina ona和O. lineata。发现的软体动物关联有助于将所研究的水平与上新世晚期联系起来。

Ostracods taxonomic study and other faunistic record from Costa Bausa (Buccheri, Southeastern Sicily)

In Costa Bausa, along the left side of the Torrente Mazzarino (NE Buccheri, SE Sicily), marine sands referred to the Pliocene by many authors for their stratigraphic position and the molluscs fauna they contain, crop out unconformably above the Miocene carbonate succession. In the present study, the taxonomy of ostracods of these sands is performed and new species are described, the foraminifera are analyzed for the first time and a taxonomic list of molluscs is also provided. The ostracod fauna is composed of specimens mostly belonging to shallow marine genera, such as Aurila, Neonesidea, Bosquetina, Callistocythere, Carynocythereis, Cistacythereis, Cytherelloidea, Cytheretta, Costa, Graptocythere, Grinioneis, Loxoconcha, Mutilus, Caudites, Pontocythere, Semicytherura, Tenedocythere, Urocythereis, Verrucocythereis and Xestoleberis. Among them, eight species are newly described: Perissocytheridea (Kroemmelbeinella) hiblaea n. sp., Aurila costabausaensis n. sp., Aurila daphnidis n. sp., Aurila mazzarinoensis n. sp., Aurila sanctiandreae n. sp., Tenedocythere forticostata n. sp., Cytheretta buccheriensis n. sp., Verrucocythereis verrucomurata n. sp.

Among planktonic foraminifera, only few specimens of Orbulina universa, O. suturalis, Trilobatus trilobus and T. sacculifer occur. The assemblage of benthic foraminifera is characterized by Amphistegina lobifera, A. lessonii, Elphidium crispum, E. macellum, Ammonia beccarii, A. parkinsoniana, Lobatula lobatula, Cancris auricula, Patellina corrugata, Quinqueloculina seminulum, Massilina oblonga, Oolina exagona and O. lineata.

The molluscs association found has helped to relate the studied levels to the Late Pliocene.

期刊介绍： La Revue de micropaléontologie publie 4 fois par an des articles de intérêt international, consacrés à tous les aspects de la micropaléontologie. Les textes, en anglais ou en français, sont des articles originaux, des résultats de recherche, des synthèses et mises au point, des comptes rendus de réunions scientifiques et des analyses de ouvrages. La revue se veut résolument ouverte à tous les aspects de la micropaléontologie en accueillant des travaux traitant de la systématique des microfossiles (et de leurs équivalents actuels), des bactéries aux microrestes de vertébrés, et de toutes leurs applications en sciences biologiques et géologiques.
