Upper Devonian goniatites and co-occuring conodonts from the Holy Cross Mountains: studies of the Polish Geological Institute collections.
The first report about the Plucki locality was given by Sobolev (1912) and Czarnocki (in the 1920s, general geology field notes--unpublished until 1989), followed by Makowski (1963, 1971) and Dzik (1985) who described a rich goniatite fauna within black bituminous limestone.
Scientists found this out using 'zone fossils' called goniatites
Los bioclastos son: equinodermos y trilobites, ambos con bioerosion, gasteropodos, bivalvos, briozoos, corales solitarios rugosos, braquiopodos, goniatites
y pequenos foraminiferos.

The majority of classes and species which lived throughout the Paleozoic still existed: trilobites, fusulines, goniatites, tetracoralaria.
Among the ammonoids, the ceratites replaced the goniatites, the tetracoralaria gave way to the exacoralaria that currently continue to form the coral reefs, and other groups like trilobites and fusulines disappeared forever.
