Wood Bjerg (Triassic of Greenland)

Also known as Jameson Land, area V

Where: Greenland (71.4° N, 22.6° W: paleocoordinates 46.9° N, 2.2° W)

• coordinate stated in text

When: Malmros Klint Member (Fleming Fjord Formation), Alaunian (215.6 - 212.0 Ma)

• fossils at several levels within member; informally called the Carlsberg Fjord Beds and the Tait Bjerg Beds; middle Norian

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; red, blue, silty, conglomeratic claystone and dolomitic, gray, yellow limestone

• Carlsberg Fjord Beds: "cyclic, bedded claystones or silty claystones and thin sandstones. This unit is also characterized by a well-developed composite cyclicity...The dominant facies in the cycles is red or violet claystone, or silty claystone with horizontal lamination. Commonly violet claystones are overlain by more silty, redbrown claystones. These claystones contain sandstone laminae, thin paleosols, and some infraformational conglomerates with bone fragments...The sandstones...are characterized by small-scale, wave-formed or current-formed cross-lamination and more rarely large-scale, current-formed cross-lamination. Upper bedding planes frequently contain dessication features, wave ripple marks, and dinosaur tracks."

•Tait Bjerg Beds: "The beds are composed of cyclically bedded, dark, clastic mudstones and lightgrey or yellowish, impure limestones or dolomitic limestones and clastic sandstones."

Size class: macrofossils

Collection methods: surface (in situ),
