Arthrophycus
Arthrophycus, and Sargassum. This subgenus classification is based on the morphological characteristics of the seaweed thallus. In addition, the distribution pattern can also be used to distinguish between Sargassum subgenera. The most common subgenera found in subtropical/temperate regions are Bactrophycus and Arthrophycus.Arthrophycus (Hall, 1852) ; DESCRIPTION: Oblique to horizontal, cross-cutting, branching burrows.

Arthrophycus burrows is distinct from other ichnospecies of this taxon in the pronounced co-planar alignment of the burrows, as opposed to the multiplanar, interweaving, “bundled” nature typicalAbstract. 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.Several ichnotaxa (especially Cruziana semiplicata, Rusophycus moyensis and Arthrophycus minimus) have biostratigraphic implications.

Abstract: The Sargassum subgenera Bactrophycus and Arthrophycus were considered to be geographically restricted to the northern and southern hemispheres, respectively. . Phylogenetic analyses of 19 Sargassum subgenus Bactrophycus species and eight Sargassum subgenus Arthrophycus species, based on a concatenated dataset of the loci ITS-2, cox3 and the rbcL-S spacer, showed that they formed a ...
