Abstract
Previous studies of the dentition and cranial base of Hadronomas puckridgi Woodburne suggested that this large, Late Miocene kangaroo might be related to the Sthenurinae. A recently recovered specimen, in which the neurocranium, rostrum and some of the incisors are preserved, reveals a more definite affinity with the sthenurines in its possession of laterally expanded postorbital crests of the frontals, reduced I2 accompanied by enlarged I3, the presence of a well-developed posterior mental foramen, a deep, posteriorly situated digastric eminence and elevated pterygoid fossa of the dentary.
