Abstract
ABSTRACT Shark teeth have been found in Upper Devonian rocks from the Broken River embayment and Burdekin Star shelf of north Queensland and in Lower Carboniferous rocks from Broken River and from near Gresford, New South Wales. Harpago ferox gen. et sp. nov. is a new tooth type which occurs in the Upper Bundock Creek Formation (possible Late Devonian), Queensland, and in the Early Carboniferous Bingleburra Formation, New South Wales. Other Late Devonian forms found in Queensland include Protacrodus spp. and Phoebodus cf. P. politus Newberry, 1889, known previously from North America, Europe and India. From one Early Carboniferous site in Queensland came a tooth of Xenacanthus sp. and one of Cladodus thomasi sp. nov., a form previously described from the Laurel Formation of Western Australia where it is associated with bradyodont teeth referred here to Helodus.
