R e m a r k s: Sceletophorus verrucosus was initially described by Fritsch (1894) as Amblypterus verrucosus . Though the general appearance of the body is reminiscent of the bodies of amblypterids from the Krkonoše Piedmont Basin, the anatomy of the skull exhibits several distinctions. These are seen in the dentition on the jaws, very strong lower jaw or small frontal in comparison to parietal. These characters are, on the contrary, common for Sceletophorus and for that reason Amblypterus verrucossus was reassigned ( Štamberg 1983) as Sceletophorus verrucosus ( FRITSCH, 1894) .
