Kuta locality 2 (Triassic of Papua New Guinea)

Where: Western Highland, Papua New Guinea (5.6° S, 144.1° E: paleocoordinates 36.0° S, 104.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Kuta Formation, Rhaetian (208.5 - 201.3 Ma)

• In places the limestone appears to grade laterally into calcareous breccia containing fragments of metamorphic rocks. The limestone rests on, and in places grades laterally into, a coarse, calcerous arkose, which in turn unconformably overlies the Kubor Granodiorite of the Omung Metamorphics. The formation is overlain by either the Late Jurassic Maril Shale or the Early Crestaceous Kondake Tuff.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone

• shallow water near fringing reefs
• The Kuta Formation consists of a suite of marine arkose, limestone, and shale outcropping in the central highlands of Papua New Guinea. The formation is 30 to 250 m thick and mainly consists of hard, buff to dark grey massive, cyrstalline, coarse to fine-grained limestone.

Size class: macrofossils

Preservation: mold/impression
