Also known as PGAP 24
Where: New South Wales, Australia (32.2° S, 149.7° E: paleocoordinates 73.1° S, 84.1° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Purlawaugh Formation, Oxfordian to Oxfordian (163.5 - 145.0 Ma)
• Hind and Helby (1969), cited by White (1981), gave age as 'Early to Middle Jurassic', but implied that age was more probably J1, since the flora occurs 'close to the base of the unit' (of the Purlawaugh Beds)
•JA: Woodward (1895) gives the age as "upper Jurassic... not earlier than the Upper Lias, and may be referable to the Lower Oolites" based on the fauna; see comments on other Talbragar collections for current age assignment; thickness of the "bed" is "about ten feet"
• group of beds-level stratigraphic resolution
Environment/lithology: lacustrine; lithified, ferruginous shale
Size class: macrofossils
Preservation: adpression
