Also known as Tasmaniosaurus holotype
Where: Tasmania, Australia (42.9° S, 147.3° E: paleocoordinates 76.0° S, 132.3° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Poets Road Siltstone Member (Knocklofty Formation), Induan (252.2 - 251.2 Ma)
• 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
• member-level stratigraphic resolution
Environment/lithology: lacustrine - small; lithified, micaceous, gray, carbonaceous shale and red siltstone
•Rotaurisaurus and Chromatobatrachus were both collected from red siltstones and Banksiops townrowi from a yellow sandstone.
Size class: macrofossils
Collected by MR Banks, JW Cosgriff in the 1960s
Collection methods: surface (float),
• UTGD: Geology Department, University of Tasmania, Hobart.
