Gosford Quarry (BMNH coll) (Triassic to of Australia)

Also known as Railway Ballast Quarry

Where: New South Wales, Australia (33.4° S, 151.3° E: paleocoordinates 64.3° S, 137.2° E)

• coordinate based on nearby landmark

When: Terrigal Formation (Narrabeen Group), Spathian to Spathian (251.3 - 242.0 Ma)

• a bed "5 ft 3 in thick". Upper part of the Terrigal Formation (formerly Gosford Formation), which is the uppermost unit of the Narrabeen Group. The Narrabeen Group extends from Late Permian–early Anisian, suggesting a late Spathian to early Anisian age for this locality (Warren & Marsicano 1998).

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; lithified, gray, muddy, sandy shale

• "some land-locked lake or sheltered estuary"
• "at the top of a group of flaggy hard sandstones, alternating with purplish grey shales with occasional bands of clay ironstone"; the sandstones are "strongly ripple-marked" and the bed itself consists of "Sandy shale and laminated mudstone, purplish grey" that is "immediately" overlain by "a lenticular band of coarse pebbles" interpreted as a flood deposit, later described as "a layer of dark grey shale"; "numerous plant remains" are variably said to be from the "intercalated shaly beds" or "the fine muds," suggesting that these are alternating laminations in the same bed

Size class: macrofossils

Preservation: mold/impression, adpression

Collected by M. Blunt, A. Lambert; reposited in the BMNH

Collection methods: salvage, quarrying,

• discovered by "Mr. Blunt, Railway Contractor, when opening a quarry for railway balast"; some material was collected by A. Lambert and most by "the Geological Survey Collector"

•Specimens also in Australian Musuem and Geological and Mining Museum of the New South Wales Geological Survey
