Fossil fauna and flora of a re-discovered locality in the Late Carboniferous Ploužnice Horizon of the Krkonoše Piedmont Basin, Bohemian Massif

Abstract

Here we present preliminary information on the fossil content of a rediscovered fossiliferous locality in the Late Carboniferous (Stephanian; Kasimovian/Gzhelian) Ploužnice Horizon, Semily Formation, in the Krkonoše Piedmont Basin of the Bohemian Massif. Several meters thick reddish to grey tuffaceous siltstones of this lacustrine horizon contain centimetre thick bone-bed layers and sporadically distributed plant remains. Common are isolated fish remains of actinopterygians, chondrichthyans, and acanthodians as well as isolated insect wings, mainly from blattoids. The biostratigraphic age is determined by blattoid insects as Stephanian B/C (Kasimovian/Gzhelian).
