Also known as Tasmaniosaurus holotype

Where: Tasmania, Australia (42.9° S, 147.3° E)

• Paleocoordinates: 82.4° S, 61.3° E (Wright 2013)

• 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
