Forbesiceras obtectum Ammonite Fossil Devon UK Genuine Specimen with COA

Description

Genuine Forbesiceras obtectum Ammonite Fossil

This listing is for the genuine ammonite fossil shown in the photographs, identified as Forbesiceras obtectum. It was collected from Shapwick Grange in Devon, United Kingdom, and is preserved in marine rocks dating to the Upper Cretaceous, Cenomanian stage. The Cenomanian lasted from approximately 100.5 to 93.9 million years ago, when warm seas and high global sea levels covered extensive areas of Europe. This is an authentic fossil specimen, not a cast, replica, or modern reproduction, and the photographs show the exact piece that will be supplied.

Upper Cretaceous Marine Fossil

Ammonites were extinct cephalopods related to modern squid, cuttlefish, octopus, and nautilus. Their coiled shells were divided internally into chambers by walls called septa. The animal lived in the final body chamber, while earlier chambers formed part of a buoyancy system. Where preserved, the meeting lines between septa and shell wall create sutures that help palaeontologists study ammonite relationships. Ammonites evolved rapidly and were widely distributed, so their fossils are valuable index fossils for correlating and dating marine sedimentary rocks.

Forbesiceras obtectum Identification

The supplied identification for this specimen is Forbesiceras obtectum. Forbesiceras is a well-known Cretaceous ammonite genus with a planispirally coiled shell and distinctive form. Depending on preservation, a specimen may show parts of the whorls, shell profile, ribbing, ornament, suture pattern, internal mould, or mineral replacement. The preservation of this exact fossil should be assessed from every photograph. Natural matrix, colour changes, exposed internal material, incomplete areas, weathering, mineral veining, and small chips are genuine features of a specimen that has passed through burial, mineralisation, uplift, and discovery.

Shapwick Grange Devon Geology

The Shapwick Grange locality preserves evidence of the ancient Cretaceous sea in Devon. Shells and other remains settled or were transported onto the seabed, where sediment buried them. Over millions of years, compaction hardened the sediment into rock while mineral-rich water preserved or replaced the original shell material. Later geological movement and erosion exposed the fossil-bearing layers again. The associated matrix and surface textures are therefore part of the specimen’s geological provenance, providing a direct physical connection to a marine ecosystem nearly one hundred million years old.

Exact Specimen for Display or Study

You will receive the exact Forbesiceras obtectum ammonite shown in the images, with no substitution. The first photograph is the main display view and the second offers another angle for inspecting its form and condition. Please refer to the photographs for full sizing and scale. This carefully selected fossil is suitable for an ammonite collection, British fossil display, natural history cabinet, teaching resource, geological study set, or memorable gift for a collector, student, or fossil enthusiast. Its documented Cenomanian age and Devon locality add important scientific and historical context.

Certificate of Authenticity

A generic Certificate of Authenticity is included with the specimen. It records the supplied identification, geological age, and locality information and carries our lifetime guarantee of authenticity. The fossil will be packed securely and carefully for dispatch. Please inspect all images before purchase because they provide the clearest record of the exact item, including every natural surface and preservation feature. This genuine Forbesiceras obtectum ammonite offers an attractive and scientifically interesting piece of Devon’s Cretaceous history and a tangible reminder of the diverse cephalopods that inhabited ancient European seas.
