Bivalves of Buchan Caves Lst., The Basin (Devonian of Australia)

Where: Victoria, Australia (37.5° S, 148.0° E: paleocoordinates 15.6° S, 175.6° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Buchan Caves Limestone Formation (Buchan Group), Early/Lower Emsian (409.1 - 402.5 Ma)

• Conodonts indicate early Emsian age (Polygnathus dehiscens zone) for bivalve-bearing beds.

• formation-level stratigraphic resolution

Environment/lithology: marine; black, gray grainstone and sandstone

• From ref. 7182: "At Buchan the sequence consists of thin basal tuff, tuffaceous sandstone, calcareous sediment, and rare conglomerate, followed by 30 to 40 m of light-coloured dolomite and dolomitic limestone, overlain by mid-grey to black, fine to medium-grained calcarenite, with a high proportion of calcilutite in the upper part of the formation."

Collection methods: Includes ANU collections B2, B3, and B5, and Macquarie Univ. localities Slocombe's and loc. 7.
