Geography
Country:Australia State/province:New South Wales
Coordinates: 33.4° South, 151.3° East (view map)
Paleocoordinates:64.3° South, 137.2° East
Basis of coordinate:based on nearby landmark
Time
Period:Triassic
Key time interval:Spathian - Bithynian
Age range of interval:248.90000 - 244.70000 m.y. ago
Stratigraphy
Geological group:Narrabeen Formation:Terrigal
Stratigraphic resolution:group of beds
Stratigraphy comments: 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).
Lithology and environment
Primary lithology:planar lamination,gray lithified muddy,sandy "shale"
Lithology description: "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
Environment:lacustrine indet.
Geology comments: "some land-locked lake or sheltered estuary"
Taphonomy
Modes of preservation:mold/impression,adpression
Size of fossils:macrofossils
Collection methods and comments
Collection methods:salvage,selective quarrying,survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:BMNH
Collectors:M. Blunt, A. Lambert
Collection method comments: 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
