A preliminary account on Devonian trilobites from Arabian Plate, SE Turkey

Authors: CATHERINE CRONIER, İZZET HOŞGÖR

Abstract: Recently, several Devonian localities and the related biota occurring from the southeastern Turkey were reinvestigated. Although, the Hakkari-Çukurca and the Diyarbakır-Hazro areas of the Arabian Plate are considered as an important source of the Devonian macrofossils from the north Arabian sector of Gondwana, the existing record of Devonian trilobites in these regions was hitherto unknown. We here report and illustrate for the first time Lower and Middle Devonian trilobites represented by three proetid pygidia and one calymenid pygidium. The morphological features of these pygidia suggest that they can be assigned to undetermined species of Gravicalymene (Calymenidae) and Podoliproetus (Proetidae), two genera known in the Lochkovian; and Pseudodechenella (Proetidae), a genus known in the Givetian.
