Where: Tasmania, Australia (43.0° S, 147.9° E: paleocoordinates 78.6° S, 163.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Malbina Formation, Wordian (266.9 - 264.3 Ma)

• Assigned to the Echinalosia hanloni/robusta zone by Briggs (1998), in the basal part of the APP4.2 palynomorph zone. Laurie et al. (2016) placed the base of APP4.2 at 266.8 Ma, coincident with the base of the Wordian (266.9 Ma in Wu et al., 2020), so a Wordian age is assigned to these collections.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, gray siltstone

Size class: macrofossils

Preservation: mold/impression

Collection methods: Given to Charles Darwin during the visit of the HMS Beagle to Hobart in February 1836, but not collected by him.
