Where: Tasmania, Australia (43.2° S, 147.1° E: paleocoordinates 79.0° S, 160.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: E Member (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 siliciclastic sediments

Size class: macrofossils

Preservation: mold/impression

Collection methods: Repository: University of Tasmania (UT), with replicas at University of Queensland
