Abstract:
Entomozoacean ostracods (pelagic so-called fingerprint-ostracods) have recently been observed for the first time in Upper Devonian sediments of the Darlik B Section from the Istanbul region, north-western Turkey. These new assemblages consist of Entomoprimitia nitida, Entomoprimitia sartenaeri, Entomoprimitia concentrica, Franklinella calcarata, Waldeckella erecta?, Rabienella n. sp. c, aff. reichi sensu Rabien & Rabitz 1958, Rabienella reichi, Richterina (Volkina) zimmermanni and Nehdentomis pseudorichterina and can be dated as Late Frasnian Entomoprimitia sartenaeri Zone (= variostriata Zone sensu Rabien 1954).
These entomozoacean ostracods indicate a faunal relationship with Germany (Rhenish Schiefergebirge, Harz Mountains, Thuringia), Poland (Holy Cross Mountains), N France-Belgium (Ardennes), Volgo-Ural Region and South China in the Late Devonian.
