Bennett, George "A Trip to Queensland in Search of Fossils," Annals and Magazine of Natural History, Vol. 4, No. 4 (1872)

I have had a long conversation with 'Charlie Pierce', an aboriginal, relative to these [Diprotodon] fossils; and he avers that they are those of an animal, long extinct, known to the natives by the name 'gyedara'. Tradition among them has handed down the appearance and habits of the animal for generations, but Charlie says he never paid much attention to the descriptions that have been given to him, but imagines the animal was as large as a heavy draught horse, walked on all fours the same as any other four-footed beast, eating grass, never went any distance back from the creeks to feed, and spent most of its time in the water, chiefly in enormous holes excavated in the banks. I told him he must mean some other animal; but he spoke most positively and asserted that the bones which we have been finding are those of the animal of which he was speaking, and that at one time the bones were very numerous about the Gowrie waterholes, where his forefathers had seen the animals themselves sporting about. I again asked him if they did not live on the leaves of trees, and his reply was that they were never seen to feed on them but always on grass, the same as a horse or a bullock.
