Although, ostracods have been recorded from seven of the Tertiary 
basins in the eastern part of Queensland, very little attention has been 
given to their systematic study in the past. 
The first reference to the occurrence of these small crustaceans in 
Queensland was made early in the year 1914, when Ball (1914a, p. 21) 
recorded “ great numbers of minute, flattened oval bodies’ ’ which he 
regarded “as the remains of ostracods” in the oil shales of the Baffle 
Creek Tertiaries between Bundaberg and Gladstone. Shortly after this, 
he (1914b, p. 73) also recorded “minute, reniform bodies — between 
and xV in. in length — showing in vast numbers on the bedding 
planes of some of the shales” of The Narrows Tertiaries between Glad- 
stone and Rockhampton, and stated that “they were much like the 
ostracod Cypris.” In 1916 Ball (1916a, p. 15), reporting on the 
Lowmead No. 1 Bore in the Baffle Creek Tertiaries, again referred to 
“the small, white, reniform bodies so characteristic of the shales, and 
especially of the oil shales” as ostracods. He mentioned that they were 
“seldom more than in. in diameter, and were enveloped by a thin, 
unsculptured, but cracked coat of a bluish-white, brittle, opalescent 
substance, which was found on chemical analysis to consist of carbonate 
of lime.” Later in the same year, Ball (1916b, p. 213) recorded from 
the Nagoorin Series, near Many Peaks, an “exposure of oil shales on 
Ubobo Creek, identical with those met in sinking and boring at Lowmead, 
even to the contained Entomostraca. ” In 1924 Jensen (p. 287), report- 
ing on the progress of the Australian Oil Corporation’s bore on Dunn’s 
farm near Beaudesert, 40 miles south of Brisbane, stated that “the 
shales from 140 ft. to 180 ft. contained abundant ostracod remains, 
especially from 160 ft.” Subsequently Ball (1924, p. 364) referred to 
these Tertiary ostracods and stated that “they are massed to the 
extinction of their individual outlines along some of the bedding planes, 
the proportion of ostracod to the total bulk of the shale reaching 
sometimes as much as 10 per cent., where several such crowded planes 
occur together.” In 1927 Jones (p. 38) recorded fossil ostracods from 
the Redbank Plains Series, in bituminous shales on portions 118, 119, and 
120, parish of Bundamba, about 12 miles south-west of Brisbane, and 
described them as “numerous small oval bodies.” In 1932 David 
(Table I.) recorded “ostracod and sporangia shales” from the Diiaringa 
Tertiaries, between Rockhampton and Emerald. Ostracods have also 
been recorded from several places in the Petrie Series, north of Brisbane. 
In 1932, Ball (p. 384) discovered numerous small “flattened kidney- 
shaped bodies which Whitehouse identified as an ostracod allied to the 
genus Cypris in fissile, low-grade oil shales on the spoil heap of 
Simpson’s well, in portion 186, parish of Nundah, about one mile E.S.E. 
of Bald Hills. Finally, the present writer (1944) has recorded ostracods 
from Brecknell’s bore on portion 222, parish of Warner, north-west of 
Strathpine, from portion 190, parish of Warner, some two miles west 
of Strathpine, and from Houghton’s bore on portion 24, parish of 
Warner, about one-quarter of a mile north of Lawnton, stating that “in 
some cases the bedding planes of the shales are so packed with white, 
chitino-calcareous, carapace valves that other material is almost 
excluded. ’ ’ 
Only one short paper dealing with the systematic description and 
identification of any of these ostracods has so far been published — 
namely, Chapman’s “Report on Samples of Surface Tertiary Rocks and 
a Bore Sample containing Ostracoda from Queensland” (1935, pp.
