M a t e r i a l: NM Pc 02880a, b, c, Pc 02881a, b, Pc 02882a, b; collected from the Dynów Mb.

R e m a r k s: The specimens are represented by fragments of the body and a disarticulated head. The elongated body is composed of vertebrae with straight neural spines which are articulated with the pterygiophores of the dorsal fin. Ribs are attached to the ventral margin of the vertebrae. In the disarticulated head it is possible to recognize the premaxillare, maxillare, and dentale. The teeth are large, with marked striation.

The species is common in Moravian localities, such as Litenčice, Kelč, Špičky, Nikolčice, Mouchnice, Nítkovice, Jestřabice, Kožušice, Rožnov pod Radhoštěm ( Kalabis and Schultz 1974, Kalabis 1975a, b, Gregorová and Požár 2003, Gregorová 2010, 2011).

Today living trichiurids are benthopelagic predators of the continental shelf and slope with depth up to 2000 m (in tropical and temperate regions; Gago 1998).

Perciformes gen. et sp. indet.

Text-fig. 2G

M a t e r i a l: one specimen NM Pc 02891; collected from the Subchert Mb.

R e m a r k s: The specimen is represented by an isolated preoperculum, preserved partly as an imprint, partly as a fossilized bone. Its ramus horizontalis is short (and robust) whereas the ramus verticalis is about twice longer. Both arms join together at almost a right angle. The posterior edge of the preoperculum is irregularly serrated, with one enlarged spine at the flexion point (see arrow in text-fig. 2G). The distal part of the enlarged spine is incompletely preserved. Classification of the specimen is difficult even though its morphology is relatively specific and it is comparable with some percichthyids, moronids, or polyprionids (see Schultz 2000: pl. 1, figs 18, 20, pl. 2 figs 29, 32). Although it is not possible to determine the specimen precisely, it is possible to say, that it does not belong to the species “ Serranus ” budensis.
