Horizon 7, Drillhole 82/42, Daly Basin, Tindall Limestone (Cambrian of Australia)

Where: Northern Territory, Australia (13.3° S, 130.6° E: paleocoordinates 26.9° N, 176.6° E)

• coordinate estimated from map

When: Tindall Limestone Formation (Daly River Group), Middle Cambrian (509.0 - 497.0 Ma)

• Late Ordian to early Templetonian: Considered to be Middle Cambrian according to Cooper 2004.

• The carbonate beds crop out as low mounds, benches and pavements, in dolines or as towers; beds marking periods of unrestricted open shelf sedimentation
• distintive 'two tone' lithology, compromising centrimetre-scale interbeds of light gray lime wackstone and darker gray dolomitic siltstone

Size class: macrofossils

Preservation: replaced with silica

Collection methods: core, acetic,
