FOSSIL TYPE, SPECIES AND SCIENTIFIC CLASSIFICATION

Teloceras triplex is an ammonite, an extinct marine cephalopod belonging to the order Ammonitida. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, and are among the most recognisable fossils of the Jurassic Period. Their coiled shells, chambered internal structure, varied ornamentation, and rapid evolutionary changes make them highly valued by collectors and important in palaeontology.

This specimen belongs to the genus Teloceras and the species Teloceras triplex. Teloceras is associated with the family Stephanoceratidae, a well-known Middle Jurassic ammonite family. Stephanoceratid ammonites are often recognised for their robust shell form, rounded whorls, pronounced ribbing, and bold three-dimensional appearance. These ammonites are important in Bajocian biostratigraphy, where their shell forms help geologists compare and date marine sedimentary rocks.

GEOLOGICAL AGE AND BAJOCIAN CONTEXT

This fossil dates from the Bajocian Stage of the Middle Jurassic, approximately 170 to 168 million years ago. The Bajocian was a time of widespread shallow marine environments across much of western Europe, with ammonites forming an abundant and diverse part of ancient marine ecosystems.

During this interval, ammonites such as Teloceras triplex lived as active swimming marine animals. Their chambered shells helped regulate buoyancy in the water column, while the living animal occupied the outer body chamber. After death, the shell could settle onto the sea floor, become buried by sediment, and eventually fossilise through mineralisation, compaction, and long-term geological alteration.

ESQUAY-NOTRE-DAME, CALVADOS, NORMANDY LOCALITY

This specimen comes from Esquay-Notre-Dame in Calvados, Normandy, France. Normandy is well known for Jurassic sedimentary rocks and fossil-bearing marine deposits, including ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine fossils. Specimens from this region are popular with collectors because they represent classic European Jurassic faunas and well-studied geological settings.

During the Middle Jurassic, the Normandy region was part of a shallow marine environment connected to wider European seas. Warm, carbonate-rich waters and sea-floor sediments helped create conditions in which ammonite shells could become buried and preserved. Over millions of years, these deposits became fossiliferous rock layers, recording the marine life that once inhabited the area.

AMMONITE MORPHOLOGY AND NATURAL FEATURES

Teloceras triplex displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The genus Teloceras is typically noted for a sturdy, evolute shell shape, rounded whorls, and strong ribbing that can give specimens a bold sculptural look. Depending on preservation, this fossil may show rib detail, whorl shape, shell ornamentation, a visible umbilicus, mineral staining, matrix attachment, natural surface wear, or fossilisation texture.

The whorls represent successive growth stages of the ammonite as the shell expanded during life. The outer shell ornamentation, including ribbing and whorl proportions, is important in ammonite identification and comparison. Natural details such as small fractures, sedimentary contact marks, weathered areas, colour variation, matrix, and mineral deposits are part of the fossil’s geological history and add individuality to the specimen.

COLLECTING, DISPLAY AND EDUCATIONAL INTEREST

This Teloceras triplex ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or Jurassic fossil collection. Its named species identification, Middle Jurassic Bajocian age, Normandy locality, and classic ammonite form give it strong collecting appeal.

It is suitable for collectors interested in French fossils, Jurassic ammonites, extinct cephalopods, marine invertebrates, palaeontology, geology, and educational fossil specimens. The natural coiled form gives the fossil immediate visual impact, while the scientific naming and locality information provide valuable context for anyone interested in prehistoric marine life and the ancient seas of Jurassic Europe.
