History and naming
The holotype specimen (QMF16853) of Ngamalacinus was collected from the early Miocene 'Inabeyance site' at the Riversleigh World Heritage Area, northwestern Queensland. It consists of a right dentary preserving all four molars. A left maxilla (QMF30300) referable to Ngamalacinus is also known from the type locality, while a right third premolar (QMF16855) is known from the 'Camel Sputum Site'. The 'Camel Sputum site' has been radiometrically dated to ~18.5–17.0 Ma, while biocorrelation suggests that the 'Inabeyance site' has an age of ~18.5–16.2 Ma.
In 1997, palaeontologist Jeanette Muirhead described Ngamalacinus timmulvaneyi as a new genus and species of thylacinid based on these fossil remains. The genus name combines the Wanyii word ‘Ngamala’ (died out) and the ancient Greek stem word ‘-kynos' (dog). The species name honours Tim Mulvaney, for their long time support of research at Riversleigh.
Description
Ngamalacinus was a small thylacinid, with an estimated weight of 5.7-8.4 kg (12.6-18.5 lbs).
