Rusophycus moyensis Mángano, Buatois et Muñiz Guinea, 2002

Description. Elongate, coffee-bean shaped bilobate structures with a central depressed area that may be either smooth or display up to eight subquadrate coxal impressions. Lobes can converge at the anterior part defining a close central depression or they may gape anteriorly. Lobes are typically covered by transverse scratch marks at the anterior part shifting to more retroverse, and commonly thinner scratch marks at the posterior part. Genal and pleural spine impressions are occasionally present. Total length is 2.9-42.6 mm (about 70% of specimens measured are within the 12.0-23.0 mm range). Trace width is 1.9-23.1 mm. Maximum depth is 4.5 mm, but commonly less than 2.0 mm. Clusters of nested individuals are relatively common. Preserved as positive hyporeliefs and possibly as negative epireliefs in fine- to very fine-grained sandstone.
