Where: Tasmania, Australia (42.5° S, 146.5° E: paleocoordinates 8.8° N, 176.4° W)
• coordinate stated in text
• local area-level geographic resolution
When: Cashions Creek Formation (Gordon Group), Llandeilo (461.1 - 458.4 Ma)
• formation-level stratigraphic resolution
Environment/lithology: perireef or subreef; lithified, oncoidal, calcareous lime mudstone and grainstone
•30 kg was sampled from another stromatoporoid mound close
•to locality 2 (within ~20 m). As with locality 2, samples were
•derived from the middle and upper part of the stromatoporoid
•mound. The stromatoporoid mound at locality 3 represents
•the lowest stratigraphic level with identifiable stromatoporoid
•mounds within the upper Cashions Creek Limestone.
Size classes: macrofossils, mesofossils
