Arthrogryposis (AMC) describes congenital joint contracture in two or more areas of the body. It derives its name from Greek, literally meaning 'curving of joints' (arthron, 'joint'; …The subgenera Bactrophycus and Arthrophycus differ to the other subgenera in having horizontally expanding, rather than vertical, leaves (Yoshida, 1983). Yoshida (1983) had difficulty in identifying clear differences between these two subgenera, so placed all species with horizontally expanding leaves distributed in the northern …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 ...
