Abstract (in english)
   The modern geographical distribution of north Gondwanan regions with Silurian sediments and faunas, shows a rather complex and disorganized picture. This apparent disorganization mainly resulted from tectonism during the Variscan Orogeny and, to a minor degree, later modifications by the Alpine Orogeny. We infer that the pre-orogenic paleogeography of the north Gondwanan Silurian featured a continuous shelf that can be divided into proximal and distal parts. The Perunica microcontinent (i.e., the present-day Bohemian Massif) was incorporated into the Variscan orogen as terrane between the Gondwana and Baltica continents. The existence of Perunica is supported by paleomagnetic data and by the distribution of Ordovician and Silurian fossil communities.
