摘要

The Fossil Point area on the south side of Tuxedni Bay is situated within Lake Clark National Park & Preserve in south-central Alaska. This aptly named topographic feature contains one of the most productive marine invertebrate fossil sites known in Alaska. Three formations, the Red Glacier Formation, Fitz Creek Siltstone, and Cynthia Falls Sandstone, all elements of the Tuxedni Group, are present in exposures at Fossil Point. Both the Red Glacier Formation and Fitz Creek Siltstone contain exceptionally rich and diverse megainvertebrate faunas with ammonites, bivalves, and belemnites. This report includes an inventory of all invertebrate taxa we observed, and an atlas is provided as Appendix F illustrating the fauna, both from our own photographs as well as illustrations given by previous workers (E. von Eichwald and Ralph W. Imlay).
