Where: Tasmania, Australia (43.2° S, 147.1° E: paleocoordinates 77.9° S, 172.3° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Kungurian (279.3 - 272.3 Ma)
• Probably a correlate of the Cascades Group (Banks). Description of lithology (limonite-coated molds in white siltstone) and presence of small Peruvispira gastropods are very similar to Deep Bay Formation (MEC field observation).
• group of beds-level stratigraphic resolution
Environment/lithology: marine; lithified, red, white siltstone
Size class: macrofossils
Preservation: mold/impression
Collected by George Frankland
• Given to Charles Darwin by surveyor-general George Frankland when Darwin visited Hobart in February 1836.
