fossils with Jurassic species, and submits further evidence of their 

 Cretaceous age. 



(c) ]\ est Australia. 



1861. Gregory, Y. T. (Quart. Journ. Geol. Soc, vol. xvii., p. 

 475), offers the first positive evidence of the occurrence of Meso- 

 zoic fossils in Australia, and, though his discovery relates with 

 certainty to ihe Jurassic, yet it probably embraces Cretaceous as 

 well, as the chalky limestones with flints and Ventriculites near 

 Gingin doubtless belong to that period. 



1870. Moore, C. (Quart. Journ. Geol. Soc, vol. xxvi.), thinks 

 that there is evidence sufl&cient to show the presence of Cretaceous 

 rocks as well as Jurassic. 



CAmOZOIC. 



Component Systems. 



[Tate and Dennant, Trans. Koy. Soc. S. Aust., vol. xvii., June 



1893.] 



Pleistocene. — Raised beaches — ^olian calciferous sandstones 

 and limestones. 



Newer Pi,iocene. — Elevated shell beds — South-east from 

 Mount Gambler and at Limestone Creek, W. Victoria. 



Osseous breccias and mammaliferous drift of the Diprotodon 

 Period. 



Older Pliocene. — Marine sands beneath mammaliferous drift 

 of the Adelaide Plain, 



Miocene. — Upland Miocene plant beds, South Australia ; low- 

 level marine bcls — Gippsland Lakes, upper beds of the Miiddy 

 Creek section, oyster banks of the River Murray cliffs, and 

 Aldinga Bay. 



Eocene. — Clays and polyzoal limestone — Rivers Mitchell, 

 Tambo, &c. ; Sale ; Gippsland ; Port Phillip Bay ; around the 

 Carbonaceous area of Cape Otway ; Camperdown ; Mu.ddy CreeK, 

 Hamilton. 



Polyzoal limestone — Mount Gambler, River Murray, St. Vincent 

 Gulf, Great Australian Bight. 



Plant beds at Vegetable Creek, New South Wales — Plant beds 

 inferior to the older basalts of Victoria. 

 Eocene. 



1810. Feron (Voy. Terres Australes) describes the fossiliferous 

 limestone at Kingscote, Kangaroo Island. 



1833. Sturt (Two Expeditions, &;c.) refers the formation of the 

 cliffs of the Lower Murray River, on fossil evidence, to Eocene.
