Description
Choffatia raguini Microconch Ammonite Fossil
Callovian Fossil from the Middle Jurassic
This genuine Choffatia raguini microconch ammonite fossil comes from Maine-et-Loire, France. It dates to the Callovian Stage of the Middle Jurassic Period and combines a named species, a recognised shell form and a documented French locality. It is a carefully chosen natural specimen for ammonite collectors, geology students, palaeontology enthusiasts and anyone building a cabinet of authentic prehistoric objects.
The photographs show the actual fossil you will receive. Its individual shape, colour, preservation, matrix and visible surface detail are represented by this exact set of images, allowing the specimen to be assessed carefully before purchase.
The Choffatia raguini Microconch
Choffatia is an extinct genus of ammonite. Ammonites were marine cephalopods with coiled shells divided internally into chambers. During growth, the animal occupied the enlarged outer living chamber while the older chambers remained within the coil. The great variety and rapid evolution of their shells make ammonites both highly collectable and scientifically valuable fossils of Jurassic marine environments.
This specimen is identified as Choffatia raguini and specifically described as a microconch. In ammonite studies, microconch refers to the smaller adult shell form found in some dimorphic ammonite groups. Microconchs are often discussed alongside larger macroconch forms when researchers interpret differences within a related ammonite population. The designation therefore adds an interesting palaeontological dimension beyond the species name alone.
When examining an ammonite, relevant features can include the expansion and overlap of the whorls, the shape and breadth of the shell, the form of the opening and the arrangement of ribs or other ornament. Please use the photographs as the definitive visual guide to the exact features and preservation visible on this individual microconch.
Geological Age and French Locality
The Callovian is a stage of the Middle Jurassic and represents a time more than 160 million years ago. Ammonites were diverse inhabitants of Jurassic seas. Because different ammonite groups changed through time and were widely distributed in marine settings, their fossils are important for comparing the relative ages of sedimentary rocks and studying Jurassic biostratigraphy.
The stated locality is Maine-et-Loire, France, providing this specimen with clear geographical as well as geological context. A fossil with a named species, microconch designation, stage and regional origin can make a particularly engaging addition to a systematic ammonite collection or an educational display.
Fossils are natural geological objects rather than manufactured ornaments. Surface variations, incomplete areas, mineral deposits, attached matrix and differences in texture may record burial, fossilisation, weathering and preparation. These natural characteristics are part of the specimen’s deep-time history and make each genuine fossil unique.
Display, Study and Collecting
This Choffatia raguini microconch is suitable for a fossil cabinet, natural history collection, classroom, office, study set or geology-themed display. It may also make a thoughtful gift for a fossil collector, amateur palaeontologist, geology student or admirer of Jurassic marine life.
For full sizing, please refer to the photographs. The fossil shown is the actual carefully selected specimen supplied, not a representative example. Both images should be reviewed for its dimensions, shell form, surface detail and overall condition.
Authenticity and Certificate
This is a genuine fossil specimen. It includes a generic Certificate of Authenticity lifetime guarantee card, providing an enduring authenticity assurance for the collector. The card will accompany the fossil.
