Title: Report on Referred Fossils ,  1983 (10/31)
This report covers 2 collections, both of probable late early Permian (Leonardian) age, from an unnamed Permian limestone in Glacier Bay National Park. Both collections contain the large distinctive rhynchonelloid Septacamera stupenda Grant, which is one of the characteristic genera that occurs in the Pybus Formation of southern Admiralty Island. There is little question in my mind that this limestone from Glacier Bay is a correlative of the Pybus. Collections retained.
