Example of Gordia?

Shown above are several examples of Gordia? sp., a distinctive trace fossil first encountered in the summer of 2011 from the lower portion of the Mississippian Price Formation (formerly Pocono). The fossil has been found north of Clover Lick, WV and in two locations near Marlinton, WV. This trace fossil appears to be a series of three-dimensional, unbranching tubes that have been actively backfilled with very fine-grained material, probably a combination of clay and organic phosphate (fecal matter). In some instances, fill material is bleached white or light grey; in others, it is black or dark orange when replaced by limonite (Fe2O3). The size, shape, and colour of examples of Gordia? found in the Price often resemble a mass of angel hair pasta. In all photos, the coin is 3 cm in diameter.

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 sediment-feeding trace and is thought to have been produced by a marine organism, most probably a worm or worm-like animal. Thus far, examples come from lower portion of the latest Devonian-Early Mississippian Price Formation 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.
