Zofia Maślankiewiczowa
A specimen of a fish, described here as Semionotus cf. bergeri Agassiz, has been found in the siderite spherolite concretion from the gray claystones of the main ore-bearing series in horizon Ia of the "Edward" mine at Czarniecka Góra near Stąporków. This specimen represents two halves of the exoskeleton from their inner sides. The caudal fin and the endoskeleton are lacking. Sediments, in which this fish has been found, belong to the Lower Lias.
