Where: Antarctica (71.5° S, 165.3° E: paleocoordinates 11.1° N, 158.7° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Spurs Formation (Mariner Group), Floran to Floran (504.5 - 500.5 Ma)
• exotic limestone blocks could belong to ?upper Molar Fm and/ or lower Spurs Fm, but the results rather argue for the rocks belonging to the Spurs Fm
Environment/lithology: open shallow subtidal; lithified limestone
Size classes: macrofossils, mesofossils
Collection methods: fossil collection was made during the GANOVEX III Expedition by F. Tessensohn; all specimens are housed in the collection of the BGR (Federal Institute of Geosciences and Natural Resources), Hannover and have been given BGR catalogue numbers; fossils are either ammonium chloride or gold coated for photographing.
