The Trace Fossil Paleodictyon within The Cruziana Ichnofacies: First Record from The Devonian in Pennsylvania
Authors:Robert Metz
Institution:Department of Geology and Meteorology , Kean University , Union , New Jersey , USA
Abstract:Offshore marine deposits of hemipelagic dark-gray shales comprising the Middle Devonian Mahantango Formation have yielded the first evidence of the trace fossil Paleodictyon from Pennsylvania. Paleodictyon occurs in conjunction with a diversity of largely deposit-feeding trace fossils belonging to the Cruziana ichnofacies, and documents another example of a shallower-water occurrence of this ichnofossil in Paleozoic rocks.
Keywords:Paleodictyon  Mahantango Formation  Middle Devonian  Pennsylvania
