Arthrophycus.
Ichnofacies can provide information about water depth, salinity, turbidity and energy. In general, traces found in shallower water are vertical, those in deeper water are more horizontal and patterned. [1] This is partly because of the relative abundance of suspended food particles, such as plankton, in the shallower waters of the photic zone ...

The stratigraphic succession of …Arthrophycus mostly occurs in sandstone, interpreted as nearshore, tidally influenced environments similar to those of the Tuscarora Formation where frequent mudstone interbeds were presumably mined for nutrients by the tracemaker.
