Dipnorhynchus kurikae
Taxonomy
Dipnorhynchus kurikae was named by Campbell and Barwick (1985) [Large species. Width to length ratio of skull high, this ratio for the palate being ca. 1.5. Large 'K' not extending between 'X' and 'L'. '1' bones meeting behind 'B'. Pineal foramen open. One to three 'D' bones present. One to three 'L' bones depending on size of 'K'. Bones 'M' and 'N' large. Rostrum narrow. Palate exceptionally thick and transverse across the articular region. Small anterior median palatal bone embraced within paired 'dermopalatines', and all fused to the pterygoids. Dentition consisting of bulbous masses similar to those of D. sussmilchi. Dentine thin over most of the palate but thicker on the marginal ridges and the bulbous 'teeth'. Mandible very long medially and with a very powerful symphysis; ratio of median length/total length ca. 0.70. Anterior furrow deep, and divided by a forward extension of the 'adsymphysial' plate, at least in large adults. 'Dentary' very short on the ventral side of the mandible but with long dorsolateral extensions around the anterior furrow. 'Splenials' and 'postsplenials' long and narrow. 'Surangular' deep and long, extending forwards to the anterior end of the labial pit. Massive bulbous tuberosities on the heel of the 'prearticulars' and smaller elongate teeth immediately behind the anterior furrow. Marginal ridge on the dentary continuous with that on the anterior end of the 'prearticulars'. Dentine thicker on the marginal ridges and bulbous teeth than elsewhere.]. Its type specimen is ANU35674, a partial skull (Posterior of skull roof), and it is a 3D body fossil. Its type locality is Dipnorhynchus kurikae-type locality, which is in a Zlichovian marine horizon in the Bloomfield Limestone Formation of Australia.
