Climatic and biotic changes around the Carboniferous/Permian boundary recorded in the continental basins of the Czech Republic

The response of lacustrine faunas to climatic oscillations around the Carboniferous-Permian transition is less prominent than that of plants. The origin of the transition between the local Elonichthys-Sphaerolepis and Acanthodes gracilis bio/ecozones around the Carboniferous/Permian boundary is impossible to deduce from the existing fossil record.
