Abstract
Lower Devonian beach or barrier-bar deposits of light-to medium-gray calcareous sandstones and medium-to medium dark-gray siltstones of the Oriskany Formation, Delaware Water Gap National Recreation Area, New Jersey, have yielded the trace fossils Planolites beverleyensis, Skolithos linearis, as well as a bivalve escape structure. Skolithos linearis, representing vertically-oriented feeding burrows within light-to medium-gray calcareous sandstones, records exploitation by opportunistic suspension feeders in a very shallow marine environment during dominant high energy conditions. In contrast, Planolites beverleyensis, representing horizontally-oriented shallow burrows within medium-to medium dark-gray siltstones, denotes exploitation by opportunistic deposit feeders during relatively abrupt, short lived lower energy levels within the same environment.
