Large Fossil Foraminifera (Nummulites sp)

Geological Period: Oligocene Epoch

Age: Approximately 33.9 to 23 million years ago

Formation/Locality: Menton, Alpes-Maritimes, France

This is a well-preserved large fossil of Nummulites sp, a genus of foraminifera — single-celled marine protozoans with complex shells (tests). Unlike most foraminifera, which are microscopic, Nummulites are famously macroforaminifera, with some specimens reaching several centimetres in diameter.

This example comes from the renowned Oligocene deposits near Menton, in the Alpes-Maritimes region of southeastern France, where Nummulites fossils are found in abundance within shallow marine limestones. These organisms thrived in warm, tropical seas, and their dense accumulations once formed entire banks of limestone — famously used by the ancient Egyptians in the construction of pyramids.

Nummulites are instantly recognisable by their coin-like, lenticular shape, with a spiral internal structure. Their abundance and size make them excellent biostratigraphic markers for dating Tertiary sedimentary rocks.

Oligocene Information

The Oligocene Epoch (33.9–23 million years ago) was a time of cooling climates and the transition to more modern ecosystems. Following the warm Eocene, global temperatures dropped, leading to the expansion of grasslands and the first permanent Antarctic ice sheets. Forests shrank, and grazing mammals like early horses, deer, and rhinos thrived in open landscapes. Primates evolved, with the ancestors of monkeys and apes appearing. In the oceans, whales diversified, and the first seals emerged. The Oligocene also saw the formation of major ocean currents, which further shaped Earth's climate. This period set the stage for the Miocene, with continued cooling and the rise of more modern mammal species.
