MEIRELES, R.P., FARANDA, C., GLIOZZI, E., PIMENTEL, A., ZANON, V., ÁVILA, S.P. (2012) - Late Miocene marine ostracods from Santa Maria Island, Azores (NE Atlantic): Palaeoecology and palaeobiogeography. Revue de Micropaléontologie, 55: 133-148, doi: 10.1016/j.revmic.2012.06.003.​

Resumo


The nine oceanic islands that comprise the Azores archipelago are located in the middle of the northern Atlantic Ocean. In this isolated archipelago there is a rich fossil record in one of the islands, Santa Maria In this island, samples were collected in the Upper Miocene composite section of Malbusca outcrop, located in the southern shores of the island, and the fossil marine Ostracoda were studied. This work represents the first report of fossil ostracods from the Azores archipelago. Thirteen species were found, representing 7 families and 11 genera (Xestoleberis, Loxoconcha, Callistocythere, Leptocythere, Hermanites, Aurila, Heliocythere, Hemicythere, Neonesidea, Cyamocytheridea and Paracypris). Among the identified species, one new species, Leptocythere azorica n. sp., is described. Loxoconcha (2 species) and Hermanites (2 species) were the most diversified genera. The collected species are mainly ornamented and typical of warm waters and epi-neritic habitats (~30-40 m of depth).
