Abstract

The Tremadocian subzones of Staurograptus tenuis. Anisograptus richardsoni. Clonograptus aureus, and Adelagraptus anriquus are given full zonal status in northern Richardson Mountains. Bryograptus ramosus Broggor and a species of Dictyonema are described from the upper Tremadotc. The occurrence of B. ramosus in the C. aureus Zone supports a correlation with shales of 3a(beta symbol) age in Norway.
