Example of Unknown Trace Fossil

Shown above is a single example of a distinctive trace fossil discovered in the summer of 2009 from the upper portion of the Devonian Millboro Shale (Harrell equivalent). The fossil was found along WV 92, southeast of Dunmore, WV. This trace fossil is preserved on the bottom of a silty shale layer; the coin is 3 cm in diameter. Also shown is a sketch reconstruction of how the trace fossil may have appeared when intact.

As part of ongoing research here at the West Virginia Geological and Economic Survey, we are trying to determine the identity and stratigraphic range of this interesting trace fossil. This trace appears to be a variation of a typical "u-shaped" dwelling burrow and is thought to have been produced by a marine organism, most probably a worm or worm-like animal. Thus far, our sole example comes from Middle Devonian Millboro Shale in eastern West 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.
