Abstract
ABSTRACT The extinct macropodine kangaroo, Protemnodon nombe, was first described in 1983 on the basis of two partial dentaries from a late Pleistocene deposit in Nombe Rockshelter, Papua New Guinea. As part of a review of Protemnodon, we noted that P. nombe differed from other members of the genus in several ways that pointed to a position outside of that genus and indeed all other known macropodine genera. The taxon possesses a unique combination of attributes of the dentary and lower dentition, including lower molars with a slight postmetacristid, a small postprotocristid and a gently S-shaped protolophid crest. The proportions of masticatory muscle insertion areas, including a broad masseteric canal for the deep masseter, resemble those of sthenurines, suggesting adaptation to tougher browsed vegetation than other New Guinean macropodines. A parsimony analysis suggests a divergence near the base of the Macropodinae, potentially in the early late Miocene. LSID of publication: urn:lsid:zoobank.org:pub:1458D336-3180-41FE-9DF5-DFAED7971807
期刊介绍:
Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia.
There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed.
Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required.
The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
