Ablation Point (Antarctica) (Jurassic of Antarctica)

Where: Alexander Island, Antarctica (70.8° S, 68.5° W: paleocoordinates 60.9° S, 24.2° W)

• local area-level geographic resolution

When: Ablation Point Formation, Kimmeridgian (155.7 - 150.8 Ma)

• formation-level stratigraphic resolution

Environment/lithology: sandstone and shale

• type section characterized by slump-folded and rafted blocks of sedimentary and volcanic rocks; blocks are predominantly sandstones, interbedded sandstones and mudstones, ignimbrites, lavas, tuffs, volcaniclastic sandstones, rare breccias, and conglomerates

Collection methods: fossils are generally sparse and poorly preserved
