Abstract

A chimaeroid species, Edaphodon eyrensisLong, 1985 (Holocephali, Chimaeroidei), from the Lower Cretaceous Bulldog Shale of the Eromanga Basin, South Australia, is reassessed as Ptyktoptychion eyrensis (Long, 1985), comb. nov. This is the oldest representative of the endemic Australian chimaeroid genus PtyktoptychionLees, 1986. An ancestor of this genus could be the Early Cretaceous chimaeroid Ischyodus thurmanniPictet and Campiche, 1858 from the northern hemisphere. Ptyktoptychion eyrensis survived in Australia in southern polar environment conditions.
