ACANTHODIAN DENTAL ELEMENTS FROM THE TRUNDLE BEDS (LOWER DEVONIAN) OF NEW SOUTH WALES

WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Acanthodian dental elements from the Trundle beds (Lochkovian-Pragian) of central New South Wales include dentigerous jaw bone fragments, tooth whorls, single teeth, and dentition cones sensu Valiukevicus. Among acanthodians, only members of the Order Ischnacanthida possess an equivalent range of dental elements. Comparisons suggest that most of the Trundle beds elements belong to an ischnacanthid taxon with close affinity to Poracanthodes. Some other elements, distinctive tooth whorls including a type not previously described, possibly belong to a species with dentition that matches no known climatiid or ischnacanthid.
