Kázmér, Miklós (1993) Pygopid brachiopods and Tethyan margins. In: Mesozoic brachiopods of alpine Europe. Hungarian Geological Society, Budapest, pp. 59-68.
Paleogeographic distribution patterns of four perforated species of the Upper Jurassic–Lower Cretaceous Pygopidae (Brachiopoda) were studied in the Alpine–Carpathian–Balkan region. Pygope catulloi and P. diphya, bearing small perforations near their umbones lived in the southern margin of Tethys, while Pygope janitor and Pygites diphyoides with large, central perforations lived on the northern margin. Their separation was caused either by a wide Penninic ocean acting as a barrier, or rather by the adaptation of the forms with smaller perforations to the nutrient-poor environment of the southern margin.
