摘要：The presence of Ordovician conodont zones from the Late Arenigian (Middle Kunda stage) to the Late Caradocian has been indicated in 8 m thick Mójcza Limestone (Holy Cross Mts,Poland). The conodont fauna of M6jcza is of the Baltic type and decidedly differs from the" fauna known from Rzeszówek,situated about 300 km to the west in the Kaczawa Mts (Sudeten Mts). Phragmodus polonicus sp.n. from Mójcza and Erraticodon balticus gen. et sp.n. from a Baltic erratic boulder havebeen described.
