INAUGURAL ADDRESS. 63 



UPPER MESOZOIC. 

 Cretaceoxts. 

 Component formations according to Jack and Etheridge : — 

 Upper Cretaceous, Desert Sandstone (including Maryborough 

 Iseds) ; Lower Cretaceous, Rolling Downs Formation. 



(a) Queensland. 

 1848. Mitchell ("Journ. Inter-tropical Australia") notes on 

 liis chart the occurrence of a Belemnite near Mount Abundance, 

 Fitzroy Downs. 



1861. McCoy ("Exhibition Essays," p. 166) determines a 

 collection of fossils from Wollumbilla, submitted by Clarke to 

 be " the marine equivalents of exactly the same age as that I 

 assign to the plant beds, i.e.., not older than the base of the Trias 

 and not younger than the lower part of the Great Oolite." The 

 Triassic genus Myophoria is quoted as evidence of that age. 



1862. Clarke (Quart. Journ. Geol. Soc, vol. xviii., p. 246) 

 announced the existence of marine Mesozoic rocks at Wollumbilla, 

 based on the fossil determinations by McCoy ; but regards the 

 beds as "altogether above the coal-beds of the Hunter River." 



1865. Keene (Quart. Journ. Geol. Soc. vol. xxi., p. 130) 

 refers Belemnites and shells from the River Belliando (Belyando) 

 to the Cretaceous epoch. 



1865-1868. McCoy submits tangible evidence of the Cretaceous 

 facies of the marine Mesozoic rocks about the head of the Flinders 

 Kiver (Trans. Roy. Soc, Victoria, vol. vi., pp. 42-46 ; to?., vol. vii., 

 pp. 49-51 ; ^J., vol. VIII., p. 41 ; ^V/., vol. ix., pp. 77-78 ; Annals 

 Nat. Hist., 1865, vol. xvr., p. 383; id., 1867, vol. xix., p. 335; 

 Intercol. Exh. Essays, 1867, p. 325), though the Wollumbilla fossils 

 are still retained as Oolitic (Intercol. Exh. Essays, 1867, p. 327). 



1867. Clarke (Intercol. Exh. Essays, p. 388) states on the 

 authority of European geologists that the Wollumbilla fossils are 

 really Cretaceous. 



1870. Moore (Quart. Jour. Geol. Soc, vol. xxvi., pp 226 et seq.J 

 describes the fossils from Wollumbilla, referring them to Jurassic. 



1872. Daintree (Quart. Journ. Geol. Soc, vol. xxviii., pp. 

 278, kc) describes the rocks of the Flinders area, classifying them 

 as Creataceous ; the Maryborough beds are placed at the base of 

 the Cretaceous and overlying the Burrum coal series. 



Etheridge fid. J describes the fossils, and refers those from 

 Gordon Downs, near Roma, and those from Wollumbilla to the 

 Oolite, p. 325.
