Barroisiceras haberfellneri Ammonite Fossil Cretaceous Coniacian Madagascar COA Genuine Rare Collector Display Specimen Certificate
£ 12.60
GENUINE BARROISICERAS HABERFELLNERI AMMONITE FOSSIL FROM MADAGASCARThis listing is for a genuine Barroisiceras haberfellneri ammonite fossil from
the Upper Cretaceous, Coniacian deposits of Madagascar. This is a carefully chosen fossil specimen, selected for its natural prehistoric interest, scientific appeal, and attractive display value. The photograph shows the actual fossil you will receive, allowing you to view the individual shape, colour, preservation, texture, and natural character of the specimen before purchase.This fossil includes a Certificate of Authenticity lifetime guarantee generic card, confirming that it is a genuine fossil specimen and not a modern replica. Full sizing information can be seen in the listing photograph. FOSSIL TYPE AND SPECIESBarroisiceras haberfellneri is an ammonite, an extinct marine cephalopod that lived during the Late Cretaceous Period. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, and they are among the most famous fossils found in marine sedimentary rocks. Their coiled shells, chambered internal structure, and rapid evolutionary changes make them highly valued by fossil collectors, educators, and geologists.As a named species, Barroisiceras haberfellneri offers stronger collector and scientific interest than a general unidentified ammonite fossil. Barroisiceras is associated with the ammonoid order Ammonitida and the family Barroisiceratidae, a group of Late Cretaceous ammonites known from marine deposits and valued for their distinctive shell forms. This makes the fossil especially appealing to collectors interested in named Cretaceous ammonites, Madagascan fossils, and extinct marine cephalopods. GEOLOGICAL AGE AND CONIACIAN SETTINGThis fossil dates from the Coniacian stage of the Upper Cretaceous, making it approximately 86 to 90 million years old. The Coniacian was a time of warm global climates and widespread shallow seas. During this interval, high sea levels created extensive marine environments where ammonites, bivalves, gastropods, echinoids, fish, sharks, marine reptiles, and other prehistoric sea life flourished.Madagascar is well known for fossil-bearing Cretaceous marine deposits, including ammonites preserved from ancient seaway and shelf environments. During the Late Cretaceous, Madagascar was part of a changing southern hemisphere marine world, with rich coastal and offshore habitats. Ammonites such as Barroisiceras lived in these ancient seas, and after death their shells settled into sediment, where they were gradually buried, mineralised, and preserved over millions of years. MORPHOLOGY AND NATURAL FEATURESAmmonites such as Barroisiceras haberfellneri had a planispiral shell, meaning the shell coiled in a flat spiral. The shell was divided into internal chambers, with the living animal occupying the final outer body chamber. Earlier chambers helped regulate buoyancy, allowing the animal to move through the water column while searching for food, avoiding predators, and navigating the ancient marine environment.Depending on preservation, Barroisiceras ammonites may show whorl shape, shell curvature, ribbing, growth lines, suture patterns, and natural surface texture. These features are part of what makes ammonites such desirable fossils, as every specimen records the growth structure of an individual prehistoric animal. The balance of scientific interest, natural symmetry, and fossilised shell detail gives this specimen strong display appeal. COLLECTOR APPEAL AND DISPLAY VALUEThis Barroisiceras haberfellneri ammonite fossil from Madagascar is ideal for collectors interested in Upper Cretaceous fossils, Coniacian ammonites, Madagascan fossils, marine cephalopods, named fossil species, and genuine natural history specimens. Its geological age places it within a fascinating period of ammonite evolution, long after the classic Jurassic ammonites but before the final extinction of ammonites at the end of the Cretaceous Period.The fossil would make an excellent addition to a fossil cabinet, educational geology collection, classroom display, natural history exhibit, or decorative curiosity collection. It is also a thoughtful gift for fossil enthusiasts, students, teachers, and anyone interested in ancient oceans, extinct marine animals, and Earth history. AUTHENTICITY AND SPECIMEN INFORMATIONYou will receive the actual Barroisiceras haberfellneri ammonite fossil shown in the photograph, not a stock image or random example. Please see the photo for full sizing and visual condition.This genuine fossil is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it a reliable and collectable specimen for anyone seeking a real Upper Cretaceous Coniacian ammonite from Madagascar with strong natural history interest, educational value, and attractive display potential.
