Title: Mesozoic macrofossil locality information for the Mount Katmai and part of the Afognak quadrangles, Alaska ,  1993
This report provides a complete listing of locality information for Mesozoic molluscan localities presented in Miller and others (1994), "Macrofossil locality map, checklists, and pre-Quaternary stratigraphic sections of the Mt. Katmai and portion of the Afognak and Naknek quadrangles, Alaska". These localities comprise the bulk of the macrofossil collections available for this area. Collections with poor locality information or that could not be found for verification of identifications are excluded. The localities are plotted on a 1:250,000 scale map of the area and are listed in sequence by the map numbers shown on Plate 1. See Table 1 for a listing of the age abbreviations used in the locality listing.
