HAVE YOU SEEN THIS FOSSIL?
On the left is a scan of the type specimen of the trace fossil Pteridichnites biseriatus from Clarke, J. M. and
Swartz, C. K., 1913b, Systematic paleontology of the Upper Devonian deposits of Maryland, Maryland Geological Survey,
Devonian Plates, Plate XLVI - 6. In the middle and on the right are several examples of Pteridichnites biseriatus
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 an interesting trace fossil, Pteridichnites biseriatus. This track is thought (by us) to have been
produced by a marine organism, most probably a brittle starfish. Thus far, we have only found Pteridichnites in Upper Devonian
shales of the Brallier, Sherr, and Foreknobs formations 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 email@example.com.
