Black Head, Gerringong (USNM coll) (Permian of Australia)

Also known as Illawarra

Where: New South Wales, Australia (34.8° S, 150.8° E: paleocoordinates 70.1° S, 159.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Gerringong Formation, Wordian (268.8 - 265.1 Ma)

• Formerly Gerringong Volcanics. A sample 2 m below the top of the formation yielded a radiometric date of 263.51 Ma, within the basal Capitanian (Metcalf et al., 2015), but nearly all fossils come from the basal Westley Park Sandstone or Kiama Sandstone members. Therefore, a Wordian age is assigned.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, volcaniclastic sandstone

Size class: macrofossils

Collected by J. Dana in 1838-1842; reposited in the USNM

Primary reference: J. D. Dana. 1847. Descriptions of fossil shells of the collections of the exploring expedition under the command of Charles Wilkes, USN, obtained in Australia, from the lower layers of the coal formation in Illawarra, and from a deposit probably of nearly the same age at Harper's Hill, Valley of the Hunter.
