Kvania n. g. and Petrocrania Raymond (Brachiopoda, Ordovician) in the Prague Basin
Minute, Dalmanella-shaped Kvania n. g. is assumed as the earliest member of the Orthostrophiinae (Orthida). Encrusting craniids Petrocrania obsoleta (Barr.) and P. inexpectata (Barr.) are so closely similar to each other that they can be distinguished only by different configurations of muscle scars in their brachial valves.
