Description
Hecticoceras cf. lairense Ammonite Fossil
Callovian Fossil from the Middle Jurassic
This genuine Hecticoceras cf. lairense ammonite fossil comes from Deux-Sèvres, France. It dates to the Callovian Stage of the Middle Jurassic Period, combining a carefully stated identification, a defined geological age and a documented French locality. It is a carefully chosen natural specimen for ammonite collectors, geology students, palaeontology enthusiasts and anyone assembling 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 belong to this exact specimen, so both images should be examined closely when considering its character and condition.
The Hecticoceras cf. lairense Identification
Hecticoceras is an extinct ammonite genus. Ammonites were marine cephalopods whose coiled shells were divided internally into a series of chambers. As the animal grew, it moved forward into an enlarged outer living chamber while earlier chambers remained behind within the coil. Their abundance, diversity and evolving shell forms make ammonites some of the most recognisable and scientifically useful fossils of Jurassic marine rocks.
The identification is written as Hecticoceras cf. lairense. In palaeontological naming, the abbreviation “cf.” indicates that the fossil is compared with, or shows an affinity to, the named species lairense. This careful notation preserves the supplied identification without presenting the species assignment as more definite than the available evidence supports. It is a useful detail for collectors who value accurate scientific labelling.
Features considered when studying ammonites can include the expansion and overlap of successive whorls, the breadth and profile of the shell, the shape of the opening and the pattern of ribs or other ornament. Please use the photographs as the definitive guide to the exact morphology and preservation visible on this individual specimen.
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 the seas during this interval. Because many ammonite groups changed through time and were widely distributed in marine environments, their fossils are important for comparing the relative ages of sedimentary rocks and studying Jurassic biostratigraphy.
The stated locality is Deux-Sèvres, France. This geographical context complements the fossil’s Callovian age and Hecticoceras identification, making it an engaging addition to a systematic ammonite collection or an educational display focused on Jurassic marine life.
Fossils are natural geological objects rather than manufactured ornaments. Variations in surface texture, incomplete areas, attached matrix, mineral deposits and differences in colour may reflect 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 Hecticoceras cf. lairense ammonite is suitable for a fossil cabinet, natural history collection, study set, classroom, office or geology-themed display. It may also make a thoughtful gift for a fossil collector, amateur palaeontologist, geology student or admirer of authentic prehistoric life.
For full sizing, please refer to the photographs. The pictured fossil is the actual carefully selected specimen supplied, not a representative example. The images provide the best guide to its dimensions, visible shell form, surface detail, matrix and overall preservation.
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.
