Polygonal cross-section is apparently non-adaptive for burrowing behaviour, but there are few examples of ichnofossils on Earth with squarish sections, e.g., Arthrophycus , (Figure 5e,f) Bulbichnnus and Oblongichnus. Subcylindrical specimens with roughly elliptical cross-section are also found (e.g., s2), although they are rarer than …In northern Australia, the subgenus 'Eusargassum' is the most common and dominant large macroalga on reefs, whereas in southern and western Australia, the subgenera Phyllotrichia and Arthrophycus ...
Arthrophycus alleghaniensis is a well-known trace fossil common in the lower Silurian of the Appalachian Basin, eastern U.S.A. Despite the distinctive morphology of this trace, with few exceptions, hypotheses about the nature of the tracemaker have not extended beyond that of a long-bodied, segmented organism. A single organic compression of a long-bodied arthropod discovered in shale ...Jan 26, 2007 · A new ichnospecies of Arthrophycus Hall 1852, A. minimus, is described from Upper Cambrian-Lower Tremadocian, shallow-marine strata of northwest Argentina.This new ichnospecies consists of small, long, regularly annulated hypichnial elements displaying subcircular to squarish cross-section and a ventral median groove. Arthrophycus brongniartii (Harlan, 1832) is common in marginal-marine deposits in the Silurian Red Mountain Formation of Alabama. The ichnospecies, the second to be named in North America, is revived and emended after long disuse.The Arthrophycus ichnogenus was first described by Harlan (1831) as Fucoides alleghaniensis, attributed to algal fossils recorded in Silurian strata, in …O ICNOGÊNERO ARTHROPHYCUS DE DEPÓSITOS SUBLITORÂNEOS DA FORMAÇÃO NHAMUNDÁ (SILURIANO INFERIOR) DA BACIA DO AMAZONAS, REGIÃO DE PRESIDENTE FIGUEIREDO

Shell lags, including crinoid columnals, brachiopods, and ten-Arthrophycus is most abundant in Ordovician and Silurian strata and is widely regarded as an ichnostratigraphic indicator of this interval. Occurrences of the ichnogenus from younger strata have been reported, but there is growing consensus that post-Paleozoic records of Arthrophycus are not valid.
Trace Fossil: Arthrophycus (PRI 76756) by Digital Atlas of Ancient Life on Sketchfab. 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 brongniartii (Harlan, 1832) is common in marginal-marine deposits in the Silurian Red Mountain Formation of Alabama. The ichnospecies, the second to be named in North America, is revived and emended after long disuse.
