INV 2014.95. 13.4 14.0 7.1 – Remarks – This very characteristic rhynchonellid species was thoroughly discussed recently by the present author ( VÖRÖS 2009) and was placed tentatively to the genus Prionorhynchia . The single specimen was not suitable to investigate the internal features; therefore, this tentative generic attribution is accepted here. P. flabellum can be distinguished from other species of Prionorhynchia by its laterally expanded subtrigonal, flabelliform outline and straight anterior commissure, with coarse zig-zag deflections. P. flabellum is a characteristic Pliensbachian species of the Alpine-Mediterranean region and this is its first record from northern Anatolia.
