This report presents in tabular form a complete listing of faunal and minor floral elements, along with their identification as known to date, for all fossils collected by field party members of the Alaska Division of Geological & Geophysical Surveys (DGGS) during their 1997 and 1998 geological mapping effort in the Healy A-6 Quadrangle. In addition, all known U.S. Geological Survey fossil localities that could be located from previously published maps are also shown on the fossil locality map and listed in the fossil register.
The purpose of this listing of fossil localities and their contained faunas is to provide biostratigraphic age control for the recent DGGS mapping efforts in the Healy A-6 Quadrangle and surrounding areas.
The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Layers include:

Members of the DGGS mapping crew that contributed fossils for this study included: Rainer Newberry, Ellen Hams, Rocky Reifenstuhl, Shirley Liss, Tom Bundtzen, and Jim Clough. We are greatly indebted to C.C. Hawley for the hospitality extended to DGGS during their stay at the Golden Zone Mine during the summers of 1997 and 1998. We also greatly benefited from his vast knowledge of the areal geology of the Upper Chulitna district. Norm Silberling was extremely helpful during discussions on the Triassic stratigraphy of the region. We also gratefully appreciate the efforts of the following paleontologists in their efforts to identify various elements of the collected fauna: George Stanley, Triassic corals and spongiomorphs; Michael Sandy and Monica Stefanoff, Triassic bivalves; Norman Savage, Paleozoic and Triassic conodonts; and Chris McRoberts, Triassic bivalves. We extend our thanks to Arthur J. Boucot, Oregon State University, Corvallis, Oregon, and David LePain, DGGS, for reviewing this manuscript.

Locations were determined visually from topographic maps in the field. Attributes were verified for consistency and completeness during the creation of the metadata.
This dataset consists only point data and does not require topology.
This dataset includes geospatial information regarding fossil sample locations in the Healy A-6 Quadrangle.
Locations were determined visually from topographic maps in the field using 1:63,360 maps that had been enlarged to about 1:40,000 (GPS was not used). The coordinates of sample and station locations were entered into an Excel spreadsheet with a digitizing tablet. Point data was manually compiled/digitized on-screen in MapInfo to create the original published map, using the field sheet for reference. The original published map was then georectified and sample locations were digitized in ArcGIS software in 2007 (see Process_Step below).

Considering the errors inherent in the USGS topographic maps, locating oneself in the field, and the methods of digitizing localities, stations, and samples are located to an accuracy between 10 and 100 meters.

Fieldwork and map compilation - The fossils were collected by field party members of the Alaska Division of Geological & Geophysical Surveys (DGGS) during their 1997 and 1998 geological mapping effort in the Healy A-6 Quadrangle. In addition, all known U.S. Geological Survey fossil localities that could be located from previously published maps are also shown on the fossil locality map and listed in the fossil register. Lengthy faunal lists for rocks of the upper Chulitna district are found in Hawley and Clark (1974), Silberling and others (1978), Jones and others (1980), and Csejtey and others (1992). Two abstracts and one paper (Stanley, 1999; Stefanoff and others, 1999; and Yarnell and others, 1999) were published in 1999, which delve respectively with aspects of the coral, brachiopod, and bivalve fauna from the Upper Triassic of the Chulitna terrane. Point data was manually compiled and digitized on-screen in MapInfo to create the original published map, using the field sheet for reference.

Digitizing sample locations - An ArcGIS shape file was created by georectifying the original map image using the four corner points and three points within the map located in the northeast, central, and southwest portions of the image. The image was then assigned a NAD 27 UTM Zone 6N projection and points were digitized using a pen tablet in the ArcGIS environment.
