Middle Devonian Emsian trilobites from Pendik, Turkey (Devonian of Turkey)

Where: Istanbul, Turkey (40.9° N, 29.2° E: paleocoordinates 18.0° S, 25.0° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Kozyatagi Formation (Pendik Group), Emsian (407.6 - 393.3 Ma)

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; dolomitic, shelly/skeletal, gray, blue, argillaceous grainstone

• "Terrigenous infillings and relative tectonic stabiliy caused seas to shallow at this time. The shoaling yielded wide spread bioclastic limestones in a high energy environment and highly fossiliferous and calcareous shales in the deeper peripheries."
• \"dark gray to bluish medium to thick bedded, recrystalized and dolomitized limestones with thin interbeds of gray shale. The composition of the limestone varies within the limits of poor to well sorted biosparites, biosparudites with angular to subrounded grains. In Pendik, the basal part of the unit is shaly and is trangressive on arkoses of Ordivician age."

Collection methods: Stratigraphy and fossil collections were by Kaya (1973), Gandl (1973) studied the trilobites, and Kullmann studied corals and goniatites.
