Later Paleozoic and Early Jurassic fossil ages from the McHugh Complex: A section in Geologic studies in Alaska by the U.S. Geological Survey during 1985 Circular 978

January 1, 1986

Late Mississippian through Early Pennsylvanian and Early Jurassic microfossils were collected from the type locality of the McHugh Complex (Clark, 1973) along the Seward Highway southeast of Anchorage (fig. 36). Radiolarians collected indicate that same of the oceanic rocks in the McHugh Complex are Early Jurassic in age. Conodonts extracted from a conglomerate clast are of Late Mississippian through earliest Pennsylvanian age. The conodont-bearing clast may have been derived from the Strelna Fornation.
