Goy Section 100.9 (Cambrian of Australia)

Where: Northern Territory, Australia (23.6° S, 134.5° E: paleocoordinates 20.5° N, 177.2° W)

When: Glyptagnostus stolidotus trilobite zone, Goyder Formation (Pertaoorrta Group), Mindyallan (499.0 - 497.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, ooidal, peloidal, sandy limestone and lithified, muddy limestone

• "...sandy and shaley limestone parasequences capped by progressively thicker dolostone and sandy dolostone benches. Large, (2 to 5 cm diameter) pisoids, ooids, sandy microbial clasts and shelly fossil remains (including trilobites, agnostids, echinoderms, gastropods, rostroconchs, phosphatic brachiopods and hyoliths) are common in this interval. Dolostone and sandy dolostone benches contain classic herringbone cross-bedding, microbialites and deci-centimetre to metre scale domal stromatolites"

Size classes: macrofossils, mesofossils

Collection methods: Commonwealth Palaeontological Collection
