We compiled detailed information on 252 occurrences of belemnites in six National Park Service (NPS) areas in Alaska. This information was based on published literature and maps, unpublished U.S. Geological Survey internal fossil reports (“Examination and Report on Referred Fossils” or E&Rs), the U.S. Geological Survey Mesozoic locality register, the Alaska Paleontological Database, the NPS Paleontology Archives and our own records of belemnites found in museum collections. Few specimens have been identified and many consist of fragments. However, even these suboptimal specimens provide evidence that belemnites are present in given formations and provide direction for future research. Two especially interesting avenues for research concern the time range of belemnites in Alaska. Belemnites are known to have originated in what is now Europe in the Early Jurassic Hettangian and to have a well-documented world-wide distribution in the Early Jurassic Toarcian.
