The
invertebrate fauna found within the Lower Devonian rocks at the Old Hunton town site locality include a number of species of trilobites, brachiopods, molluscs, coral, bryozoa, echinoderms, annulids,
and cephalopods, as well as other phyla that are currently not offered for sale here. Each category listed here in our online store contains individual specimens for sale. Specimens are segregated by
type and are identified to species level when possible. Haragan and Bois D'Arc trilobites and brachiopods have been identified within several Oklahoma Geological Survey Bulletins spanning from the
early 1950s up until the late 1970s. Some of the assignments among trilobites have been modified in more recent years. The majority of the other invertebrates that are offered here for sale are not
easily identified from published sources.
