Fig. 3 in A New Siphonotretid Brachiopod from the Silurian of Central-Western New South Wales, Australia

Fig. 3. Stratigraphic column of the BM section showing lithology and all sampled horizons. Lithological details of massive red and grey lensoidal limestones and sampled horizons for the 5.87 metres of section around the Llandovery-Wenlock boundary, from sample BM 3.65 to BM 16.80, is enlarged in the middle. Key to lithology as for Fig. 2; blank areas indicate no exposure. Modified after Valentine et al. (2003). Distribution and abundance of Orbaspina gelasinus n.gen. and n.sp. recovered from each sampled horizon in the massive red and grey lensoidal limestones is shown to the right. Sample size in kilograms for each horizon is given in brackets after each sample number.
