Abstract:
Well preserved trilobites were discovered in 1985 by Comalco during the drilling of Manya-6, eastern Officer Basin, between 967.70 and 970.13 metres depth. They occur within the Ouldburra Formation which in Manya-6 extends from a depth of 571.4m to 1685.6m. The Ouldburra Formation comprises mixed carbonate/siliciclastics, marine carbonates and evaporites which were deposited during a series of transgressions and regressions of an epeiric sea and on an intermittently emergent flanking sabkha. The Ouldburra Formation is part of sequence C1.2 of Gravestoek and Hibburt (1991) which in the Flinders Ranges includes part of the Parara Limestone.
