Macropus sp. nov. 'fat-tailed, spotted kangaroo'
Taxonomy & Nomenclature
This undescribed species is purely hypothetical, based upon a single petroglyph from the world famous Burrup Peninsula site.
Dingle (2015) quotes archaeologist Ken Mulvaney talking about the petroglyph:
"Unlike most kangaroos and wallabies this has a bulge, a bit like the fat-tailed sheep. It appears there was possibly a fat-tailed macropod that lived in the Pilbara sometime before 10,000 years ago. It actually has what appear to be spots as a decoration… It is unlikely to have been an artistic design embellishment ... It is likely that what we have is an animal that went extinct before the sea levels came in, before the Holocene period of Australia."
