Abstract

This paper discusses contemporaneous knowledge of conodont, foraminiferal, stromatoporoid, tabulate and rugosan faunas through the Devonian carbonate platform of Moravia. In basal parts of the Moravian Devonian, upper Emsian to lowermost Eifelian is documented by conodonts in the Jeseniky Mts. Conodonts are rare in the Middle Devonian and the Middle/Upper Devonian boundary is not yet documented by conodonts. The most important change in the conodont assemblage lies in the upper part of the Pa. triangularis Zone in Moravia; for detailed zonation of Famennian, the system based on phylogeny of Palmatolepis is accepted.

Five foraminiferal zones correlated with the standard conodont zonation are distinguished in the Upper Devonian.

Several stromatoporoid assemblages were distinguished in the interval from Eifelian to Frasnian; stromatoporoids pass into the Famennian.

Eight tabulate coral biozones are known at present, some of which are capable of more detailed division. Biostratigraphically significant tabulates range from Eifelian to the Famennian Pa. crepida Zone.

Seven rugose coral biozones are described, ranging from Eifelian to the upper Frasnian Pa. gigas or Pa. triangularis Zones with a local fauna known from the Famennian Pa. crepida Zone. Stromatoporoid and coral faunas are correlated with standard conodont zonation of the Upper Devonian.

Stromatoporoid and coral shallow water faunas locally pass from upper Frasnian to Famennian without pronounced systematic changes. However, both diversity and abundance of coral and stromatoporoid faunas decrease noticeably across the Frasnian/Famennian boundary beds.
