Paper, 'On the generic identity of Sceparnodon and Phascolonus' by R [Richard] Lydekker Lydekker writes: 'In the year 1872, Sir Richard Owen described and figured in the ‘Phil. Trans.’ two imperfect lower jaws of a large extinct Wombat, from the Pleistocene of Queensland, under the name of Phascolomys (Phascolonus) gigas, the term Phascolonus being employed in a subgeneric sense. The species Phascolomys gigas, it should be observed, was founded by the same writer at an earlier date, upon the evidence of a detached cheek-tooth. Subsequently Sir Richard Owen described and figured certain imperfect upper incisors, from Queensland and South Australia, characterised by their peculiarly flattened and chisel-like shape, under the new generic name Sceparnodon, which was suggested from their contour.'
