摘要：Conodonts extracted by means of hydrofluoric acid from the Upper Tremadocian chalcedony beds of the Holy Cross Mts. are described. Two multlelemental simple-cone apparatuses are recognized: Drepanoistodus deltifer pristinus (Viira) and Acodus? sp. Drepanoistodus deltifer (= Paltodus deltifer) Zone is subdivided into D. deltifer pristinus and D. deltifer deltifer Subzones. Correlation of the subzones over northern Europe,and approximate intercontinental correlation,are established. Possible differences in internal structure are recognized between the Tremadocian cordylodids and simple cones.
