RC10B (Cretaceous of Australia)

Also known as Gippsland Basin, Rintoul Creek 10B

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

• coordinate estimated from map

When: Tyers Conglomerate Formation (Strzelecki Group), Neocomian (145.0 - 130.0 Ma)

• In the Tyers River Subgroup.

Environment/lithology: terrestrial; sandstone

• 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 c.200 m thick basal unit is dominated by polymict, ortho- and paraconglomerates interbedded with coarse-grained, quartzose sandstones and minor siltstones and is assigned to the Tyers Conglomerate. This locality has discontinuous conglomerate lenses.

Size class: microfossils

Preservation: charcoalification, original sporopollenin

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