From the approximately 80 fish specimens so far recovered, approximately 65 % of them have been indentified at the generic level (Pl. 2a - f). The most abundant is the genus Eosemionotus followed by Habroichthys and Saurichthys. Locally, Eosemionotus specimens can be found in large numbers on single bedding planes (possibly mass mortality events). So far also five specimens of the genus Placopleurus, and five specimens of an early neopterigian close to the “semionotiform” were found. The fish fauna found in the dark laminated bituminous limestone differs from that found in the bright laminated to thin bedded dolomite. In the dark laminated bituminous limestone the genus Eosemionotus is the most frequent, while in the bright laminated to thin bedded dolomite it is not so common. In these latter beds the neopterigians are quite common, but so far they have not been recovered from the dark laminated bituminous limestone.
