Summit of Saint-Gérand-le-Puy (Miocene of France)

Also known as Summit of Saint Gérand le Puy

Where: France (46.3° N, 3.5° E: paleocoordinates 46.2° N, 1.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Indusial Limestone Formation, Aquitanian (23.0 - 20.4 Ma)

Environment/lithology: lacustrine - large; lithified limestone

• The deposits of St-Gérand-le-Puy are part of the infill of the Limagne Basin, a rift basin the origin of which is related to the alpine orogeny. Likely a brackish/hypersaline lake environment.
• Bosc notes that the limestone is composed nearly entirely of tiny agglutinated tubular fossils, forming an irregular mass.

Size class: macrofossils
