Conningham (Triassic of Australia)

Where: Tasmania, Australia (43.1° S, 147.3° E: paleocoordinates 76.2° S, 132.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: 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).

•Three major and several minor clay-pebble conglomerate lenses containing fossil bone are interbedded with shales and sandstones on the faces of the sea cliffs. The major lenses range from about 30 to 100 cm in thickness and the minor ones are 10cm or less thick. They are all lumped together as one locality: all are within 10 m of each other stratigraphically, they are identical in lithology, and all of the fossil fragments were actually collected from tumbled blocks on the shoreline; these blocks offer no means of determining the particular lens on the cliff face from which they fell.

• group of beds-level stratigraphic resolution

Environment/lithology: "channel"; pebbly, muddy conglomerate

• "Clay-pebble conglomerate"

Size class: macrofossils
