Where: Victoria, Australia (38.1° S, 146.5° E: paleocoordinates 80.1° S, 75.1° E)

• coordinate estimated from map

When: Exalt Member (Rintoul Creek Formation), Neocomian (145.5 - 130.0 Ma)

• In the Tyers River Subgroup.

Environment/lithology: terrestrial

• The Gippsland Basin is a roughly east-west orientated rift and epicratonic sag basin located along the southeastern margin of Victoria, Australia. The basin was initiated in the latest Jurassic or Early Cretaceous as rifting propagated along a roughly west-east axis between Austrailia and Antarctica.
• The Exalt Member of the Rintoul Creek Formation consists of thick quartzose to feldspathic sandstone packages interbedded with minor siltstones. This locality is composed of siltstones and sandstones. It has intraformational clasts, trough cross-bedding, fragmentary foliage (unidentifiable), cross-laminae, flat laminae, planar cross-bedding, discontinuous sandstone lenses, discontinuous siltstone lenses, extraformational clasts (pebbles-cobbles), ferruginous concretions, and wood/axes (<30 cm long).

Size class: microfossils

Preservation: original sporopollenin

Collection methods: surface (in situ), chemical, sieve,
