ammonites
Z 64/1, Cabora Bassa Basin (Triassic of Zimbabwe)

Where: Mashonaland Central, Zimbabwe (16.2° S, 30.3° E: paleocoordinates 50.8° S, 11.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Pebbly Arkose Formation (Karoo Group), Carnian (235.0 - 221.5 Ma)

• considered equivalent to the Molteno Formation of South Africa and of "Ischigualastian" age; Carnian

Environment/lithology: "floodplain"; graded, fine-grained, micaceous, pyritic, brown sandstone

• "alluvial plain sedimentation"
• "Light-brown, fine-grained micaceous sandstone which is moderately sorted and relatively coarse bedded. The sandstone fines upward to siltstone and even to mudstone. Pyrite concretions occur sporadically. Scour-and-fill structures are developed at the base of the cyclic units, whereas disiccation cracks and slump structures are more common in the upper portions"

Size class: macrofossils
