Lower Devonian vertebrate microfossils from Turkey

A small sample of vertebrate fish scales, predominantly those of a thelodont agnathan, the turiniid Turinia sp. cf. T. nachoi, and a few from the acanthodian gnathostome Nostovicina laticristata, have been found in the Lower Devonian Güneyyaka Formation in the Ovacik slice of the Tahtalidağ Nappe north of Alanya (Antalya Unit) in the Antalya region, southwest Anatolia, southern Turkey. The area is considered to have been on the northern Gondwana margin at that time. The fish microfossils support a Lochkovian to possible early Pragian at youngest (Early Devonian) age for the limestone beds, and are amongst the oldest known Turkish vertebrate fossils.
