摘要：
The Kokarkuyu Formation (Early Triassic) from the curuk Dag section, Western Taurus, Antalya Nappes, Turkey was carefully sampled for a taxonomic study of the ostracods. A total of 57 species belonging to 15 genera are recognized. Three species are newly described: Monoceratina hussonae sp. nov., Reviya sylvieae sp. nov. and Eukloedenella adcapitisdolorella sp. nov. The present data are the first Neo-Tethyan illustration of ostracod survival in the aftermath of the end-Permian extinction in a refuge of microbial origin. Ostracods are abundant within the microbialites at the base of the formation and allow the reconstruction of ontogenetic series for nine species. Shape variations through ontogeny are described for seven species: Bairdia? kemerensis, Praezabythocypris? ottomanensis, Liuzhinia antalyaensis, Paracypris gaetanii, Reviya curukensis, R. sylvieae and Eukloedenella adcapitisdolorella. Paedomorphosis through deceleration and peramorphosis through acceleration are identified as secondary survival strategies following the end-Permian extinction. [GRAPHICS]
