Embayment Hill (Devonian of Australia)

Where: Western Australia, Australia (18.3° S, 126.5° E)

• Paleocoordinates: 24.0° S, 114.8° E (Wright 2013)

• coordinate based on political unit

When: transitans conodont zone, Gogo Formation, Frasnian (382.7 - 372.2 Ma)

• "The Gogo Formation has been dated as Late Givetian (hermanni Zone) to early Frasnian

•(falsiovalis to punctata conodont Zones), based on revision of the conodont fauna and radiolarians from the upper part of the formation (Nazarov et al. 1982, Nazarov & Ormiston 1983, Klapper 2009). The fish-bearing nodules primarily contain conodonts of the transitans conodont Zone." (Long and Trinajstic 2010)

Environment/lithology: reef, buildup or bioherm; nodular, silty lime mudstone and siltstone

• "The Gogo Formation consists of a sequence of inter-reef siltstone and thin beds of limestone. The latter contain the fossil-bearing nodules, which are usually bedded and range in size from around 2.5 to 36 cm in diameter. The concretions are composed of silty micritic limestone and are commonly found to have developed around a fossil fish or phyllocarid crustacean."

Size class: macrofossils

Preservation: concretion
