†Arthrophycus harlani Conrad 1852. PaleoDB taxon number: 405471. Belongs to Arthrophycus according to Conrad 1852. Sister taxa: Arthrophycus brongniartii, Arthrophycus lateralis, Arthrophycus minimus, Arthrophycus parallelusArthrophycus brongniartii, Arthrophycus lateralis, Arthrophycus minimus, Arthrophycus parallelusThe 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).

Among the attempts to subdivide the genus into certain subgroups, 5 subgenera system of J. Agardh (1889) was universally adopted with or without minor modification up to present. He recognized following subgenera: Phyllotrichia, Schizophycus, Bacthrophycus, Arthrophycus and Sargassum (=Eusargassum).The presence of Mammillichnis ichnogenus in the Gura Șoimului Formation, cropping out in the Pleșu Anticline axis, represents the first paleoichnological argument that confirms the Early Miocene age of this unit. This argument broadens the distribution areal from Vrancea half-window at south, to Bistrița half-window at north. The regional …

It derives its name from Greek, literally meaning 'curving of joints' (arthron, 'joint'; grȳpōsis, late Latin form of late Greek grūpōsis, 'hooking').Children born with one or more joint contractures have abnormal fibrosis of the muscle tissue causing muscle shortening, and therefore are unable to ... japan adultindigenous certificate programs Buy Trace 3D models.
