Middle devonian trace fossils from the onondaga formation, delaware water gap national recreation area, new jersey
Middle Devonian marine deposits of medium-to dark-gray calcisilts and clayey limestones of the Onondaga Formation, Delaware Water Gap National Recreation Area, have yielded the trace fossils Nereites missouriensis, Psammichnites isp., as well as a trace fossil resembling Psammichnites. Both forms represent largely horizontal to slightly inclined deposit feeding strategies occurring in relatively low-energy, well-oxygenated, moderately deep marine waters with moderate sediment influx.
