Nimbacinus

• Bullock Creek, Riversleigh, Australia

Nimbacinus is a thylacine genre of the late Oligocene to middle Miocene.

Features

Nimbacinus was as large as a fox and brought a weight of about 5.3 kg on the scales, so it is slightly heavier than Muribacinus, the smallest representative of the Thylacinidae. There is an almost complete skeleton of Nimbacinus known having anatomically very conservative features. The skull was 13 cm long, but, in comparison with that of today's bag wolf hardly any differences. The lower jaw was about 9 cm long and had a typical marsupial dentition with three Schneidezähnenauf with a canine, three premolars and four molars each pine bough. Here, the first incisor is greatest, the canine was made ​​very large. The premolars and molars were relatively simply built with jagged peaks, the size increased to the rear. Overall, the dentition is little specialized and not as advanced as that of the recent bag wolf.

Paleobiology

The carnivore is nourishing Nimbacinus probably lived as hunters on the forest floor, at the same time with various other thylacine species. Compared to its small body size Nimbacinus had a very high bite force, according to the calculations of 264 Newton reached. While this is less than one-sixth of what a lion reached today (1.77 kN), based on body and muscle mass and a calculated number Beißkraftquotienten but this is 1.7 times stronger. This high bite force enabled Nimbacinus to kill, significantly larger prey.

Nimbacinus is a rather primitive representatives of Thylacinidae, his nearest relative is Ngamalacinus, but this has been a more modern set of teeth on. However, the phylogenetic relationships within the Thylacinidae are still largely unclear. Partial Nimbacinus occurs simultaneously on with Mutpuracinus. There are known two types: Nimbacinus thick soni Muirhead & Archer, 1990, lived in the late Oligocene to middle Miocene and is one of the Riversleigh Local Fauna, Riversleigh on. Nimbacinus richi Murray & Merigian, 2000, lived in the middle Miocene and part of the Bullock Creek Local Fauna of the Camfield Beds in the Northern Territory to. The genus name is derived from the word Nimbacinus nimba the Aboriginalsprache Waanyi, meaning " small", CINUS derived from the Greek κινος ( cinemas ), which is translated as "dog". Thus Nimbacinus the "little dog ".
