then from what cause? Not from the advent of man; savages do 

 not exterminate. Have we hitherto considered this fauna younger 

 than it really was ? possibly, but for the solution of these questions 

 we must look to further accumulation and study of palseontogical 

 evidence. So far as the writer can see at present the Age of the 

 fauna preserved in the Darling Downs deposits cannot well be 

 later than Early Pliocene.
