L e c t o t y p e ( Štamberg 1991 ): Specimen figured by Fritsch (1895 , pl. 131, fig. 12) deposited in the National Museum, Prague under No. M 1217 (positive) and M 881 (negative). L o c u s t y p i c u s: Kounov, district Rakovník, Czech Republic . S t r a t u m t y p i c u m: Kounov Member, Stephanian B, Upper Carboniferous, Kladno–Rakovník Basin. O c c u r r e n c e: Bone fragments and mostly isolated scales occur in the Late Carboniferous sediments of the Central and West Bohemian late Paleozoic basins and the Krkonoše Piedmont Basin. Štamberg and Zajíc (2008) enumerate a complete list of the localities with Progyrolepis speciosus . D i a g n o s i s: Maxilla with long and low maxillary plate, the length/height ratio of the maxillary plate is 1.6, the ratio of the length of the maxillary plate to the length of the anterior narrow maxillary part is 0.9. The sculpture on the maxilla is formed by conspicuous tubercles and ridges. The sculpture of these irregularly arranged tubercles and ridges covers the entire lateral surface of the maxillary plate, except for the narrow strip on its anterior border, which is smooth. The surface of the large conical teeth carries numerous vertical grooves with small oval bumps regularly placed among them. R e m a r k s: Progyrolepis speciosus represents a large predatory fish. Despite the absence of a complete specimen, the fragments of the body and the formation of the bones of the skull figured previously by Fritsch (1895) provide a good reconstruction of the morphology of the fish.
