Abstract
The stromatoporoid fauna of the Emsian, Eifelian and Givetian carbonates of northern Yukon Territory and northwestern District of Mackenzie are much different from those of the Frasnian rocks of Alberta. The stromatoporoids collected from the lower part of the sequence, the Michelle and Gossage Formations (Lower Devonian to Eifelian), are poorly preserved and difficult to identify. A rich fauna was collected in the Ogilvie Formation (upper Eifelian to Givetian) from which 16 species are described. Notable among these fossils are new species of Tienodictyon (T. jainaraini), Hammatostroma (H. vermiforme), Stictostroma (S. cavosite), Pseudoactinodictyon (P. cranswickense). Stromatoporoids from the Hume Formation also are described.This publication has 0 references indexed in Scilit:
