Nelson 1986 <p>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&nbsp;(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.&nbsp;</p> application/pdf 10.3133/70180235 en U.S. Geological Survey Later Paleozoic and Early Jurassic fossil ages from the McHugh Complex: A section in <i> Geologic studies in Alaska by the U.S. Geological Survey during 1985 Circular 978</i> reports
