Reference
Title: Report on Referred Fossils ,  1961 (09/22)
This reports covers fossils from Southeastern Alaska, Admiralty Island, collected in 1961. Older collections from the same area, as well as elsewhere in Southwest Alaska, are also included. The only significant fossils present are Aucellas, and these appear to be of Late Jurassic and earliest Cretaceous age. Preservation of many collections is poor, and specific identification is at best a guess.
