Species

Zygomaturus[2] is anextinct genus of giantmarsupial belonging to the familyDiprotodontidae which inhabited Australia from the LateMiocene toLate Pleistocene.

Description

[edit]
Z. trilobus jaw

It was a large animal, weighing 500 kg (1100 lbs) or over 700 kg (1544 lbs)[3] and standing about 1.5 m (4.9 ft) tall and 2.5 m (8.2 ft) long.[4] As in other large marsupials, the sinuses within the skull are very large, likely to reduce weight.[5]

Palaeobiology

[edit]

In an analysis of remains fromCuddie Springs, the carbon isotope ratios suggests that it consumed bothC3 andC4 plants, with adental microwear texture indicative ofbrowsing.[6] Preserved remains suggest thatZygomaturus was widely distributed over Australia during thePleistocene.[7]

Evolution and extinction

[edit]

The earliest members of the genus such asZygomaturus gilli appeared during the LateMiocene, around 8 million years ago.[8] It is thought that the youngest species,Zygomaturus trilobus became extinct during the latter half of theLate Pleistocene, with typical estimates being about 45,000 years ago, around the time ofAboriginal arrival in Australia.[9] A surprisingly late date between 33.3 ±3.7 Kya and 36.7 ±5.1 Kya was reported in 2017 from theWillandra Lakes Region in New South Wales, which if correct would represent the latest known date for any extinct Australian Megafauna.[10]
