The Laroona Formation and Mount Podge Limestone are defined for the lo
wer conglomerates and micaceous sandstones, and the upper coralline li
mestones exposed in the Mount Podge area, north Queensland. Acanthophy
llum (Acanthophyllum) clermontense-Protomacgeea fauna from these two u
nits (mainly from the Mount Podge Limestone) in the area is of late Em
sian age, and comparable with other Emsian to early Eifelian coral fau
nas from Queensland and New South Wales. Fifteen species belonging to
14 genera (one genus and 7 species new) are described from the Mount P
odge Limestone, including Microplasma ronense (Mansuy 1913), Lekanophy
llum laroonaense sp. nov., Sanidophyllum sp., Tabulophyllum carinatum
sp. nov., Carlinastraea callosa sp. nov., Australophyllum sp., Xystrip
hyllum cf. dunstani (Etheridge 1911), X. cf. magnum Hill 1942a, Taimyr
ophyllum pedderi sp. nov., Laroonaphyllum jacki gen. et sp. nov., Acan
thophyllum (Acanthophyllum) clermontense (Etheridge 1911), Disphyllum
(Disphyllum) poracouvinense sp. nov., Phillipsastrea sp. cf. maculosa
Hill 1942a, Protomacgeea minor sp. nov. and Thamnophyllum sp., and one
new species Gaynaphyllum runningense sp. nov. from the very top of th
e underlying Laroona Formation.
