and also from the very characteristic forms below them, there can be no doubt that they 
should be referred to the Upper Oolite j)eriod The Putataka beds are of 
marine origin, and contain Middle Oolite fossils.” The Flag Ilill series is marine.* ^ 
It may be conjectured that the Mataura Beds represent at least some portion of ' 
the Ipswich Formation, but the preponderance of marine beds in the Mesozoic Trias of 
iNew Zealand presents a striking contrast to Tasmania. 
Of the whole Queensland Mesozoic System, betweeli the uppermost fresh-water 
Coal Measures of the Bowen Fiver Coal Field (Permo-Carboniferous), and the Foiling 
Downs Formation (Cretaceous), i.e., the Burrum, Stewart’s Creek (Eockhampton), and 
Ipswich Beds, my Colleague saj^s that the organic remains are principally those of 
plants, with a strong Mesozoic facies, and oscillating in all probability between the Trias 
and U])per Oolite in age. Since ho expressed the above opinion, however, my 
Colleague has, together with Professor Edgeworth David, attributed a Triassic age to 
some of the Hscw South Walts equivalents of the Ipswich (and Burrum?) Formations, 
As the Mesozoic Formations have been more closely studied in New South Wales, it 
will be well to extend the range of the Queensland (Burrum and Ipswich) downward 
to the base of the Trias. As, on the other hand, the Ipswich Formation appears to 
graduate upwards, without break, into the Cretaceous of the Foiling Downs, it is 
probable that the Queensland strata cover the whole of the time between the base of 
the Trias and the top of the Oolite. It thus becomes convenient to classify the 
Burrum and Ipswich Formations respectively as Lower and Upper Trias- Jura. 
It is possible that in the sandstones of Murphy’s Creek and other localities on 
the slopes of the Toowoomba Fange, we may have the equivalents of the Hawkesbury 
Sandstones.
