Hofmann, Hans J. 1981 12 15: First record of a Late Proterozoic faunal assemblage in the North American Cordillera. Lethaia, Vol. 14, pp. 303–310. Oslo. ISSN 0024–1164. Megafossils are reported from an unnamed Late Proterozoic formation in the Sekwi Brook area of the Mackenzie Mountains of northwestern Canada. The biota includes the metazoans Inkylovia sp. and Sekwia excentrica Hofmann n, gen., n. sp., the trace fossils Gordia sp., Gordiu? sp., and Torrowangea sp., as well as structures of problematic affinities. The metazoans support a latest Proterozoic age for the containing beds. 0 Early Metazoa, body fossils, trace fossils, Problematica, Late Proterozoic, North American Cordillera, Markenzie Mountains, Canada.
