First Early Carboniferous lungfish (Dipnoi, Ctenodontidae) from central Queensland

Abstract

Toothplates and skull bones from a dipnoan referred here to the genus Ctenodus occur frequently in the tetrapod-bearing member of the mid Viséan Ducabrook Formation located near the type section at Ducabrook, near Springsure, central Queensland. This is the first record of a Viséan ctenodontid, and of the genus Ctenodus, in Australia, in the East Gondwana region, and in the southern hemisphere.
