Horizon 5, 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

• small collection-level geographic resolution

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.

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, gray limestone and lithified packstone

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

Size class: macrofossils

Preservation: cast, replaced with silica

Collection methods: core, acetic,
