Shown above are several examples of the distinctive, arrow-shaped trace fossil Bifungites sp., first described in 1940 from
Late Devonian rocks in the Libyan desert. All of the photographed fossils were collected along US 33, east of Elkins, WV.
As part of ongoing research here at the West Virginia Geological and Economic Survey, we are trying to determine the geographic
and stratigraphic range of this interesting trace fossil, Bifungites sp. This modified burrow is thought to have been produced by a marine
organism, most probably a worm or worm-like animal. Thus far, our only examples of Bifungites come from Upper Devonian shales of
the Foreknobs Formation in eastern West Virginia and western Virginia. We would be extremely interested in hearing from anyone who has
seen this fossil elsewhere, especially from older or younger rocks or from other locations. Pictures and locality information would be
welcome. Please contact Ron McDowell, Senior Research Geologist at WVGES, at mcdowell@geosrv.wvnet.edu.
