From these, fourteen are determined as ichnogenus (Arthrophycus tenius, Halopoa annulata, Nereites irregularis, Cosmorhaphe sinuosa, Helminthorhaphe flexuosa, Helicolithus tortuosus, Desmograpton dertonensis, Desmograpton ichthyforme,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

Mar 1, 2020 · Seilecher (2000) concluded that the most likely tracemaker of the subrectangular Arthrophycus burrows belong to polychaete annelids, while Rindsberg and Martin (2003) considered the short-bodied arthropods as potential tracemakers for Arthrophycus and similar ichnotaxa. Arthrophycus is an iconic ichnogenus known from lower Paleozoic clastic strata worldwide, yet its origin remains controversial.

Hall (1852) redescribed Harlan's fossils as Arthrophycus, but the first reinterpretation of these structures as a trace fossil was presented by Nathorst (1881).

Trace fossil (or, ichnofossil) specimen of Arthrophycus alleghaniensis from the Silurian Medina Limestone of Orleans County, New York (PRI 76756).

The ichnogenus Arthrophycus, characteristic of Ordovician-Silurian sedimentary rocks, is described by the first time in the Pyrenees. This ichnogenus is located in fine-grained sandstones of the upper part of the Cava Formation, on the Upper Ordovician rocks of the southern slope of the la Rabassa Dome, close to the Andorra-Spain border. Arthrophycus, Bactrophycus, Sargassum and Phyllotrichia) are now subdivided into a total of 12 sections and further subdivisions were abandoned. Two possible new sections need to be assessed. In the present paper, we raise the hypothesis that S. subgen. Arthrophycus could be merged to S. subgen. Bactrophycus, and that S. subgen. ….

A. parallelus is smaller (narrower) than most other Arthrophycus (3.5–4.5 mm for A. parallelus vs. 10–20 mm for other Arthrophycus; Table 2), but falls within the upper range given for A. minimus (1.8–4.8 mm) recently described by Mángano et al.
