Comments

A unique specimen showing well preserved scales (see second image for close up). Archaeomene tenuis is a superficially similar species which also occurs at this site and often has well preserved scales, but can be distinguished from Cavenderichthys talbragarensis by the different skull morphology, tail shape and dorsal fin which opposes the anal fin.
