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.

Description

Fossil Identification

This large fossil foraminifera is identified as Nummulites sp, with the supplied additional identification recorded as Oliogocene. Nummulites is a genus of fossil benthic foraminifera, recognised for its comparatively large, disc-shaped or lenticular tests and tightly coiled chamber structure. The abbreviation “sp.” indicates that the specimen is assigned to the genus Nummulites without a more specific species name being stated.

Locality

The specimen is associated with Menton, Alpes-Maritimes, France. Menton is situated on the Mediterranean coast in southeastern France, within the Alpes-Maritimes department. This locality gives the piece a clear regional geological context and makes it an appealing addition for collectors who focus on French fossils, Mediterranean geology, foraminifera, or Paleogene marine life.

Geological and Scientific Interest

Foraminifera are microscopic to comparatively large single-celled organisms that construct protective shells, known as tests. Their tests may become preserved within marine sediments and can display intricate chamber arrangements, coiling patterns, and surface textures. Nummulites are especially notable among fossil foraminifera because some members of the genus produced tests large enough to be readily appreciated as hand specimens.

As a fossil foraminifer, Nummulites offers a direct connection to ancient marine environments. The form of the test reflects the organism’s growth pattern, with successive chambers added during development. Coiled architecture and layered chamber construction are important features studied by palaeontologists when comparing different foraminiferal groups. These fossils are valued both for their scientific significance and for their distinctive natural appearance.

Collector Appeal

This specimen is suited to fossil collectors, geology students, natural history displays, teaching collections, and anyone interested in the fossil record of marine organisms. It can be displayed as a representative fossil foraminifera specimen or used as a starting point for learning about microfossils, benthic marine life, sedimentary geology, and the use of fossils in geological interpretation.

The Menton, Alpes-Maritimes, France locality adds geographical interest, while the Nummulites sp identification provides a useful focus for research into fossil foraminiferal morphology and classification. Its large foraminifera designation makes it particularly suitable for collectors who want a specimen that clearly demonstrates the unusual scale and recognisable form associated with this group.
