16 QUEENSLAND FOSSIL FLORAS “ 
These plant remains have been carried down to the 
sea probably by river action and deposited along the 
shallow-water coastal belt; plants and marine shells 
(Nucula, etc.) have been found on the one specimen. 
There is to be noted in this small collection a very 
decided increase in the proportion of Gymnosperms, and 
there is no doubt that the flora is distinctly newer than 
that of the Walloon Series. 
The Maryborough Series is regarded as the equivalent 
of the Rolling Downs Series of Western Queensland, but 
so far no plant remains have been obtained from the latter. 
The Rolling Downs Series has generally been considered 
as of Lower Cretaceous age, but the determination of the 
age of the Burrum Series from its contained fossil plants 
throws some doubt on this (see below, p. 17). 
(it) The flora of the Burrum Series. An examination 
of the plant material from the Burrum Series has been 
completed, and the descriptions are now being published 
by the Queensland Geological ‘Survey as Publication 
No. 263. This flora includes now thirty-five species, as 
follows :—

Cladophlebis australis 
?Thinnfeldia lancifolia 
7 Dictyophyllum sp.

Phyllopteris expansa, sp. nov. 
Microphyllopteris gleichenioides 
Microphyllopteris acula sp. nov., 
Baiera bidens 
Araucariles polycarpa 
Araucarites Arberi, sp. nov. 
Brachyphyllum crassum

Teniopteris howardensis, 
sp. mov. 
Teniopteris sp. 
Ginkgo digitata 
Nageiopsis zamioides (2) 
Pagiophyllum Jemmetti 
Pagiophyllum peregrinum (?) 
?Sphenolepidium sp. 
Podozamites Kidstoni 
Podozamites lanceolatus 
Podozamites sp. 
Nilssonia mucronatum occurs in Western Queensland 
in the Winton Series which is regarded as the equivalent 
of the Burrum Series, so it should perhaps be included in 
the above list.
