Paleontological Resources of the USGS in Denver
For more than 100 years the USGS has been maintaining a fossil collection in Denver. The fossils are valuable resources for researchers in the USGS, other federal agencies, industry, and academia. The collections are the biostratigraphic standard from which timing of important events in earth history are dated. The collections are routinely used as the research basis for analyses of geologic mapping age control, climate change, faunal diversity, and extinction events.
Primary collections housed in the Denver repository include:
In addition to the 1.2 million fossils, the collection includes a vast amount of metadata consisting of locality and taxonomic cards, ledgers, supplementary identification reports, field notes and maps.
