Stratigraphy
Formation:Knocklofty Member:Poets Road Siltstone
Stratigraphic resolution:member
Stratigraphy comments: Palynology and vertebrate biostratigraphy have been used to argue for an earliest Triassic age for the Knocklofty Formation (Cosgriff 1974; Camp & Banks 1978).

Vertebrates collected at several layers within the quarry: Chomatobatrachus comes from a 4 m thick sequence of red siltstones at the very base of the quarry. Tasmaniosaurus was found in a gray siltstone that comes from 40 m above the base of the quarry. Blinasaurus from a sandstone from higher up in the quarry than Tasmaniosaurus
Lithology and environment
Primary lithology:micaceous,gray lithified carbonaceous "shale"
Secondary lithology:red siltstone

Includes fossils?Y
Lithology description: Tasmaniosaurus comes from a "hard, light to medium grey, blocky, micaceous shale" "The reptile occurs in a coarse-grained, well-sorted, siltstone with laminae about 0.1 mm thick. The rock consists predominantly of very angular to angular quartz grains and muscovite flakes in equal porportions and carbonaceous matter" (Camp & Banks 1978) Rotaurisaurus and Chromatobatrachus were both collected from red siltstones and Banksiops townrowi from a yellow sandstone.
Environment:lacustrine - small
Geology comments: "Ponds or small lakes" (Camp & Banks 1978)
