[5] In an analysis of remains from Cuddie Springs, the carbon isotope ratios suggests that it consumed both C3 and C4 plants, with a dental microwear texture indicative of browsing.

[6] Preserved remains suggest that Zygomaturus was widely distributed over Australia during the Pleistocene.

[7] The earliest members of the genus such as Zygomaturus gilli appeared during the Late Miocene, around 8 million years ago.

[8] It is thought that the youngest species, Zygomaturus trilobus became extinct during the latter half of the Late Pleistocene, with typical estimates being about 45,000 years ago, around the time of Aboriginal 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 the Willandra Lakes Region in New South Wales, which if correct would represent the latest known date for any extinct Australian Megafauna.
