INV 2014.104. 10.6 11.3 7.7 4.9 Remarks – This species was well-documented by profuse illustrations by RAU (1905, l.c.) and HÖFLINGER (2012, l.c.) and on this basis, the identification of our specimen seems satisfactory. C. persinuata stands very close to the type species of the genus, C. dalmasi ( Dumortier, 1869) , but it is more convex, has more numerous ribs, weaker deflections in the uniplication, and its outline is more pentagonal in dorsal view, with somewhat concave anterior part. C. persinuata is a characteristic late Pliensbachian brachiopod of the NW-European (German) region but it was recorded also from the Pliensbachian of the West Carpathians, the Balkans (Kotel), the Crimea and now from the Pontides ( Turkey).
