Skeletons and tadpoles of Anura belonging to the palaeobatrachids have been collected in the freshwater Early Oligocene sediments of the “Pirin” Mine, near the village of Brezhani, southwestern Bulgaria. Skeletons of cyprinid fishes are also present in the same bituminous argillite. The anatomical study of the palaeobatrachid skeletons has shown that they should be determined as Palaeobatrachus cf. grandipes (Giebel). This new find extends the geographical distribution of this species and of the family Palaeobatrachidae to the southeastern Europe.
