Ganbulanyi

The holotype, QMF 24537, was found at the Encore site at the Riversleigh World Heritage Area, in the Boodjamulla National Park of northwestern Queensland. It consists of a fractured and worn upper first or second molar. In 1998, Stephen Wroe described this specimen as representing a new genus and species, which he named Ganbulanyi djadjinguli. An upper second or third premolar was also referred to the taxon, but later became the type specimen for a new species of Malleodectes, M. moenia, in 2011. The generic name is derived from the Waanyi word for “native cat”. The species name, pronounced “jad-jin-gulli”, is a combination of the Waanyi words for “to eat” (Djadji) and “bone” (nguli). ==Description==

Ganbulanyi is distinguished from other dasyuromorphs primarily by various details of its molar. The upper molar is massive but low crowned. The occlusal (biting) surface of the protocone is small but robust, while the lingual face (side nearest the tongue) is steeply inclined. Viewed from the top of the tooth, the centrocrista is straight. The postmetacrista is aligned from front-to-back on the tooth. It retains stylar cusp C, but lacks stylar cusp E. All of the primary cusps are positioned close together. The stylar shelf is significantly small in size. G. djadjinguli was very similar in size to the Tiger quoll, being no larger than 7 kg (15.4 lbs). ==Classification==

Wroe (1998) tentatively referred Ganbulanyi to the family Dasyuridae. In addition, a close relationship with Sarcophilus harrisii was hypothesised on the basis of two to four synapomorphies. However, some doubt was cast by the author as G. djadjinguli retains plesiomorphic traits such as an upper third premolar and stylar cusp C on its upper molar. ==Paleobiology==

Fossils of Ganbulanyi known from the Encore site at the Riversleigh World Heritage Area, which has been estimated to be early Late Miocene in age. At the time, Australia experienced less rainfall and rainforests either became fragmented or disappeared across the continent. The Riversleigh area would have been covered in woodland or open forest. G. djadjinguli lived alongside other dasyuromorphs like Mayigriphus; the phascolarctid Phascolarctos; the vombatid Warendja; the diprotodontid Neohelos; the palorchestid Palorchestes; the thylacoleonid Wakaleo; the macropods Ekaltadeta and Wanburoo; and the phalangerid Trichosurus. == References ==
