Arthrophycus
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. The nature of the Arthrophycus tracemaker has historically been a matter of debate with two main hypotheses: the 31 Des 1981 ... Autores.
