Where: Antarctica (72.0° S, 68.5° W: paleocoordinates 77.9° S, 48.5° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Triton Point Formation (Fossil Bluff Group), Late/Upper Albian (105.3 - 99.6 Ma)
Environment/lithology: "floodplain"; lithified sandstone
•The Triton Point Formation consists of a wedge-like package of fluvial sedimentary rocks which thickens from 200 m at Triton Point in the north of the study area to c. 950 m at Citadel Bastion, Titan Nunataks and Coal Nunatak in the south.
Size class: macrofossils
Preservation: mold/impression, original cellulose
Collection methods: All specimens are housed at the British Antarctic Survey and catalogued with the prefix KG.
•The material was examined under an Olympus SZH-10 stereo microscope, and photographed using Kodak Technical Pan film. Line drawings were made using a
• camera lucida attached to the Olympus microscope. The following terms are used in the species synonymies for those taxa figured and listed by Jefferson (1981).
