This report covers 66 collections of fossils, mainly from the North Slope of Alaska, but a few from the slate and greywacke belt of southern Alaska. Many of the fossils are poorly preserved and cannot be identified. The majority of specimens from the North Slope are from the Fortress Mountain, Torok, and Kukpowruk Formations or equivalents, and are of Albian age. Several collections are of Late Cretaceous age. The fossils retained in the Menlo Park office have been given USGS numbers; the remainder have been discarded.
