Errolosteus

Errolosteus goodradigbeensis is an extinct buchanosteid arthrodire placoderm. Its fossils have been found in Emsian-aged marine strata of New South Wales, Australia.

The holotype of E. goodradigbeensis, ANU 21806, was described at the same time as its sympatric relative, Arenipiscis. Errolosteus can be distinguished by having a comparatively short, broad skull.
