ammonites
Level BH-3b, Section B - Germig, Tibet (Jurassic of China)

Where: Tibet, China (28.7° N, 86.1° E: paleocoordinates 27.8° S, 47.3° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Germig Formation, Early/Lower Hettangian (201.6 - 196.5 Ma)

• Just above level B2 of ammonites

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, fine-grained, gray, calcareous sandstone and lithified siltstone

• The diverse epifauna, in combination with their common association with crinoids and a high degree of encrustation and bioerosion on the shells, suggest a shallow, warm, and low turbidity marine environment of normal salinity.

Size class: macrofossils
