The Arthrophycus ichnogenus was first described by Harlan (1831) as Fucoides alleghaniensis, attributed to algal fossils recorded in Silurian strata, in southeastern Pennsylvania (USA). Hall (1852) redescribed Harlan's fossils as Arthrophycus, but the first reinterpretation of these structures as a trace fossil was presented by Nathorst (1881).Ichnogenus Arthrophycus Hall, 1852 Arthrophycus isp.
