NOTES ON THE PETRIE SERIES, SOUTH-EASTERN QUEENSLAND. 93 
This rather small assemblage represents the complete list of fossils 
previously recorded from the Petrie Series. The discovery of additional 
fossil plants, invertebrates, and fish remains is therefore of some 
importance. 
The most interesting collection has been obtained from the steeply 
dipping low-grade oil shales which outcrop on the southern bank of the 
South Pine River just below Roghan road pumping station, on portion 
127, parish of Nundah. This assemblage includes numerous fragments 
of fossil Eucalypt leaves including one entire well preserved leaf which, 
according to C. T. White (1942), bears a very strong resemblance to 
Eucalypiv s propinqua , the “grey gum,” which is quite common in the 
district to-day. At least two other species of the genus Eucalyptus are 
also represented in this fossil flora, but, because of their presence only 
as leaf fragments, identification or comparison with either fossil or recent 
species of this genus is impracticable. On the same horizon has 
been found a probable fossil insect gall, the first, as far as can be ascer- 
tained, to be recorded from Australia, although they are not uncommon 
in the Tertiary flora of the United States. As insect galls are quite 
common on gum and other leaves to-day, the association with fossil 
Eucalvpts in these beds is of particular interest. Several small seed- 
like bodies and one fragment of an indeterminate dicotyledonous leaf 
have also been collected from these shales. The most abundant fossils, 
however, are sedges, which, according to S. T. Blake (1942), appear to 
belong to the present day genus Eleocbaris, and possibly to the species 
Eleocharis equisetina Presl, which they very closely resemble. Apart 
from this flora* a number of fragmentary fish remains, including gener- 
ally isolated vertebrae and other bones, spines, and scales, have been 
found in the low-grade oil shale, as well as a cast of the right valve of 
an oval-shaped Unionid, which most resembles in shape the present day 
form Velesunio balonnensis (Conrad). Probable fossil worm castings, 
tracks and burrows also are quite common in these shales, but, although 
an intensive search was made, no ostracods or insects could be discovered. 
A small collection of dicotyledonous leaves has also been obtained 
from the steeply dipping sandstones and shales which outcrop about one 
and a-half miles W. of Strathpine in the vicinity of portion 256, parish 
of Warner, and C. T. Wliite (1942) has stated that several of them 
resemble leaves of the following living genera: — Ghnelina, Acacia, 
Melaleuca, and Callistemon. Probable worm castings or infilled tracks 
were also found in these biscuit-coloured shales. Further specimens of 
dicotyledonous leaves, some with the cuticle preserved, have been 
collected from the greyish-coloured sandstones and oil shales from Neill’s 
shaft nearby. Apart from these, casts of two valves of elongate shaped 
Unionids were found in the sandstone, and one in the oil shale which 
immediately underlies it. Unfortunately, they are all too poorly pre- 
served to allow comparison with either fossil or recent forms. A certain 
amount of coalified plant material is associated with the low-grade oil 
shale brought up from Neill’s shaft, and, protruding upwards across 
the laminations of the shale, not uncommonly are found what are thought 
to be the mud infillings of the internal cavity of fossil sedges preserved 
in their growing positions. 
In addition to the fossils recorded by L. C. Ball (1932, p. 221) from 
portion 190, parish of Warner, the writer has also found numerous 
impressions of fossil sedges in the very slickensided shale brought up 
from a shaft recently sunk some 15 feet N.E. of the old well referred
