<<Any chance the material was redeposited from a Triassic formation? Are there any Triassic units near the Australian locality or in its subsurface?>>
On page 987 they pose the question: Is this a dicynodont?
"In short, we can find no reason to doubt that QMF15.990 originated from the
Rolling Downs Group. It seems quite certainly to be Early Cretaceous in age
and was probably introduced into the marine environment by flood-waters that
also carried the carcases of sauropods, ankylosaurs and ornithopod dinosaurs
(Molnar 1991, 1996a,b)."
halfway plausible? *curious*
have nice days.
