Matilda Site, Elderslie Station (AODL 85) (Cretaceous of Australia)

Also known as Australovenator wintonensis type locality

Where: Queensland, Australia (22.2° S, 142.5° E: paleocoordinates 52.0° S, 132.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Phimopollenites pannosus pollen zone, Winton Formation (Rolling Downs Group), Late/Upper Cenomanian (99.6 - 93.5 Ma)

• "Winton Formation (Fig. 2), latest Albian–Turonian, Cretaceous; AODL 85 specifically is of Cenomanian age (Bryan et al., 2012)" (Poropat et al. 2014)

•"Samples from the Matilda underwent zircon dating indicating a Cenomanian age (ca. 95 Ma) for the site (Figure 6 in [2]) [2,3]" (White et al. 2013

• bed-level stratigraphic resolution

Environment/lithology: fine channel fill; fine-grained, concretionary claystone and sandstone

• "deposit accumulated as part of a low energy, silt-rich, abandoned channel fill deposit, most likely as part of an ox-bow lake, with distinctive ‘billabong’ morphology"
• "a fine-grained clay sediment bounded by upper and lower labile sandstone horizons"

Size classes: macrofossils, mesofossils

Preservation: concretion

Collected in 2005-2006

Collection methods: quarrying, surface (float), surface (in situ), mechanical,
