Multielement composition of the conodont species Polygnathus xylus xylus Stauffer, 1940 and Ozarkodina brevis (Bischoff and Ziegler, 1957) from the Upper Devonian of the Canning Basin, Western Australia

More than 200 conodont clusters and 1300 discrete elements belonging to Polygnathus xylus xylus and Owrkodina brevis were recovered from a sample of the Upper Devonian Napier Formation in the Oscar Range of the Canning Basin, Western Australia. A study of them indicates that both P. xylus xylus and Q brevis had a multielement structure of 15 elements, belonging to seven element types: M (2), Sa (1), Sc (4), Sb (2), Sd (2), Pb (2), and Pa (2). The better preserved and more complete clusters of P. xylus xylus have been used as a basis, with reference to a recent find of an impression of a conodont animal, for a reconstruction of the head region, showing the position of the conodont elements. Two groups of elements with distinctly different functions are recognised. The anterior discernens elements (M, Sa, Sc, Sb, and Sd) serve to sort particulate food matter, and the posterior contundens elements (Pb, Pa), to crush the food particles prior to their entry into the gut.
