£ 10.20
Genuine Onychoceras tenue Ammonite Fossil from Aveyron, FranceThis Onychoceras tenue ammonite fossil is a genuine Lower Jurassic specimen from
Aveyron, France. Dating from the Upper Toarcian and associated with the Insigne Zone, this fossil represents a fascinating marine cephalopod from the ancient Jurassic seas of Europe. It is a carefully chosen fossil specimen with strong geological interest, attractive collector appeal and a desirable French locality.The photograph shows the actual fossil you will receive, so this is an individual specimen rather than a stock image or representative example. For full sizing and visible condition, please see the listing photo. This fossil includes a Certificate of Authenticity lifetime guarantee generic card.Fossil Type and Species InterestOnychoceras tenue is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish and nautilus. Ammonites lived inside coiled external shells divided into a series of internal chambers. These chambers helped regulate buoyancy, allowing the animal to move through the water column while the soft-bodied animal occupied the final living chamber at the front of the shell.Onychoceras is a Jurassic ammonite genus valued by collectors for its distinctive coiled shell form and fine ornamental features. The species tenue is associated with a slender, refined appearance, with shell proportions and ribbing that give it a delicate but recognisable fossil character. Depending on preservation, ammonites of this type may show fine ribbing across the whorls, a compressed shell profile and subtle ventral features typical of many Toarcian ammonites.As an ammonite, Onychoceras belongs to the order Ammonitida, a major group of Mesozoic cephalopods that became extremely important in Jurassic biostratigraphy. Ammonites evolved rapidly, were abundant in ancient seas and spread widely across marine environments, making them excellent fossils for dating and comparing rock layers.Geology, Age and Insigne ZoneThis specimen comes from the Lower Jurassic, specifically the Upper Toarcian Stage. The Toarcian was an important interval in ammonite evolution, with many elegant, ribbed and compressed ammonite forms developing across European marine basins. The Insigne Zone is an ammonite biozone within the Upper Toarcian and is useful for identifying and correlating fossil-bearing rock layers of this age.During the Upper Toarcian, the region now represented by Aveyron in southern France was part of a marine setting connected to wider Jurassic seas. Fine sediments accumulated on ancient sea floors, preserving ammonites, belemnites, bivalves, brachiopods and other marine life. Over millions of years, these remains were buried, mineralised and preserved within sedimentary rocks, creating the fossil-rich deposits now valued by collectors and palaeontologists.French Toarcian ammonites are especially popular because they often combine scientific value with attractive preservation. A specimen from the Insigne Zone offers a direct connection to a precisely defined interval of Jurassic time, making it appealing not only as a display fossil but also as an educational geological specimen.Aveyron Locality and Collecting AppealAveyron, France, is known for fossil-bearing Jurassic deposits that have produced a variety of ammonites and other marine fossils. Fossils from this region are appreciated for their connection to classic European palaeontology and the diverse ammonite faunas of the Lower Jurassic.This Onychoceras tenue ammonite combines a named species, a defined Upper Toarcian age, Insigne Zone association and French locality, giving it strong appeal for collectors of ammonites, Jurassic fossils, cephalopods and natural history specimens.Authenticity and PresentationThis Onychoceras tenue ammonite fossil is a genuine specimen selected for its natural character, geological interest and display quality. It is supplied exactly as shown in the listing photograph, so the fossil pictured is the actual piece you will receive.The included Certificate of Authenticity lifetime guarantee generic card provides reassurance for collectors, educators, gift buyers and natural history enthusiasts. This makes the fossil suitable for a serious fossil collection, educational use or display in a cabinet, study, classroom, office or geology-themed room.Display, Collecting and Educational ValueThis Onychoceras tenue ammonite is ideal for collectors of French fossils, Jurassic ammonites, Lower Jurassic cephalopods and natural history specimens. Its Upper Toarcian age, Insigne Zone association, Aveyron locality and classic ammonite form give it excellent appeal as both a display fossil and an educational specimen.As a genuine Lower Jurassic ammonite from France, this fossil offers a direct connection to the ancient marine world that existed millions of years ago. It would make an excellent fossil gift, collector’s item, teaching specimen or display piece for anyone interested in ammonites, cephalopods, palaeontology, French geology and the fossil-rich marine deposits of the Jurassic Period.
