Southern boundary of Boyce's selection, Talbragar River (Jurassic of Australia)

Where: New South Wales, Australia (32.2° S, 149.3° E: paleocoordinates 75.0° S, 88.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tithonian (152.1 - 145.0 Ma)

• Latest Oxfordian-Tithonian, or early Tithonian: 151.55 +/- 4.27 Ma (error bar falls within Kimmeridgian). Although previously regarded to be of Early Jurassic age (Hind & Helby 1969), a latest Oxfordian–Tithonian (Late Jurassic) age has recently been determined by SHRIMP (Sensitive High Resolution Ion Microprobe) analysis of zircon crystals obtained from this unit (Turner et al. 2009).

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified, tuffaceous siliciclastic sediments

• The deposit represents a remnant of sedimentary accumulation in a freshwater lake
• Sediment is largely derived from consolidated volcanic ash

Size class: macrofossils

Preservation: adpression

Collected by Arthur Lowe

• Repository: Australian Museum, Sydney. The deposit was originally discovered by Mr. Arthur Lowe, of Wilbertree, Mudgee. Also collected by Mr. Cullen.
