Genus Chronozoon de Vis, 1883

Type species: Chronozoon australe de Vis, 1883 , Chinchilla, Pliocene.

Chronozoon australe de Vis, 1883

Fig. 6E .

Material.— QM F610 (holotype, calvarium) from Chinchilla , Australia, Pliocene .

Remarks.— De Vis (1883a) originally suggested the species might share affinities with sirenians. Mahoney and Ride (1975) suggested that it might be part of the skull of a giant wombat, whereas Reinhart (1976) interpreted it as a likely sirenian of unknown affinity. We consider Chronozoon australe as species inquirenda.

Stratigraphic and geographic range.—Pliocene; eastern Australia.
