Contains polygon boundaries between mappable geologic units and polygon codes for the mappable geologic units. Contains values for the Potential Fossil Yield Classification (PFYC) for ranking the potential of a geologic unit to produce scientifically significant fossils. Also contains fields for geologic ages and sort codes for sorting the units by time. Detailed documentation on the mapped units can be found in the accompanying state generated reports. Additional fields were added to the source data including earliest geologic age, latest geologic age, PFYC justification, PFYC rank (1-5), and a coded representation for the standardized BLM coloring scheme for PFYC maps. The Potential Fossil Yield Classification (PFYC) system is a predictive model for areas that are likely to produce fossils of scientific interest. This model is used to evaluate potential impacts to fossils in ground-disturbing actions, or to help inform research.

Attribute values derived and based on an unofficial standard for Potential Fossil Yield Classification (PFYC) for the BLM's Paleontological Resources division. No guarantee of logical consistency. No formal tests were performed. US States not included in this product are not completed and under development. The state of California is represented by the area with complete data available (Desert District), all other data is still under development. As accurate as the source data. No formal tests were run to confirm this. Each state's data was created by individual state BLM offices or contractors based on the unofficial BLM Paleontological Resource PFYC standard. Individual datasets were shared with the National BLM Paleo Resource Division and reviewed by a team member for accuracy and completeness compared to the unofficial standard. All acceptable state data was compile into a National dataset. The compiled data was reviewed by the whole BLM Paleo Resources Division team for the correct PFYC Classification code. 2022 Andrew Smith U.S. Department of the Interior, Bureau of Land Management (BLM), Paleontological Resources Cartographic Technician 406-896-5278 5001 Southgate Dr Billings MT 59101 US a2smith@blm.gov 27993 EPSG 6.5(3.0.1) BLM_Natl_PFYC_GeoFormations BLM's Potential Fossil Yield Classified (PFYC) geologic formation attribute information. user defined Feature Class 27993 OBJECTID Internal feature number.

Comes from the original source map. user defined free text MAP_REF_CD Source map reference code. It is created by combining the 2 letter state code, the first 4 characters of the primary map author’s last name, plus the first and middle initial, plus the 4 digit year of publication. Example: MTHamiJA1960. If there are multiple source maps by the same author in the same year, append a letter after the year to differentiate between them. Example MTHamiJA1960a. user defined free text GEO_CD Combined state, map reference, and geologic formation codes. It is created by combining the Map Reference Code (above) and the original geologic symbol. Example: MTHamiJA1960Kgr. This will automatically distinguish this map’s concept of Kgr from any other in the data set, giving a unique code for these units across the entire data set. By convention, the first letter of the geologic code from the source map will represent the rock unit’s geologic age. Occasionally the characters are not easily convertible alphanumeric characters. If that is the case, see Appendix 2 for recommended characters for the Geologic age portion of the code. user defined free text STATE_CD US State's two letter abbreviation. user defined 2 letter US Postal State Code user defined GlobalID GlobalID GlobalID 38 0 0 GlobalID created_user created_user String 255 0 0 Created User that does not exist. created_date created_date Date 8 0 0 Creaetd Date that does not exist. last_edited_user last_edited_user String 255 0 0 Last Edited User that does not exist. last_edited_date last_edited_date Date 8 0 0 Last Edited Date that does not exist.
