This specimen is from Mulbring Quarry where first year students from UoN visit on an excursion. It is one of the most fossiliferous rocks around, with fossils on every surface. The quarry provides excellent exposure to a layer that has been referred to as the ‘Fenestella Shale’ (really a fine grained sandstone) that is dominated by the bryozoan Fenestella. It is part of the Branxton Formation, a middle Permian shallow marine unit in the Sydney Basin of NSW Australia.
Fossils present include a number of species of bryozoans, brachiopods, crinoids, gastropods, pelecypods (including Eurydesma sp.), rugose corals and rare trilobites. This collection comprises a classic cold climate shallow marine fauna that flourished at the time when Australia was near the south pole. Small dropstones are also present in the quarry.
