initially discovered by glaessner and walter (1975), "arumberia" was described as a problematic cupped-body fossil of an ediacaran soft-bodied organism characterized by hollow compressible ribbed bodies composed of flexible tissue. brasier (1979) deemed it a pseudofossil arising from turbid water flow in shallow marine or deltaic environments, due in part to physical and morphological similarities to flume-induced structures previously observed by dzulynski and walton (1965). "arumberia" appears as a poorly-delimited series of fine parallel grooves arising from a single region or point. "arumberia banksii" consists of an array of straight to gently curved parallel to subparallel ridges (rugae) about 1 – 3 mm wide and separated by flat to gently concave furrows of 1 – 7 mm in width. relief from ridge top to furrow bottom is less than 1 mm. ridge ranges in length from 1.5 cm to 14.5 cm. generally the ridges are parallel, but they also bifurcate. ridges are developed on plane and rippled surfaces"."
