Abstract

In this study, Frasnian brachiopoda fauna of the Gumuþali formation in the Saimbeyli area (Eastern Taurides) has been identified and described for the first time in Turkey. The measured section, located near Naltaþ village, Gumuþali formation is well exposed and very rich in macrofossils. This macrofossils occur in local accumulations within the limestones and sandstones. The section which represents lower part of the formation is formed by fossiliferous limestones at the basal part, by sandy limestone-shale alternation at the middle part and by sandstones interbedded with thin shales at the top. The sequence was deposited in a shallow marine environment. It contains brachiopods, corals and subordinate bryozoa and crinoidal elements. The detemined brachiopoda assemblage includes Douvillina dutertrei (Murchison), Cyphoterorhynchus arpaensis (Abramian), Desquamatia sp., Cyrtospirifer bisinus (Lehon), Cyrtospirifer schelonicus Nalivkin, Cyrtospirifer sp., Apousiella bouchardi (Murchison), Spinatrypina chitralensis (Reed), Uchtospirifer multiplicatus Brice. This assemblage can be correlated with those from the Frasnian of Iran, Afghanistan and Western Europe.
