£ 12.60
GENUINE OXYCERITES ASPIDOIDES AMMONITE FOSSILThis listing is for a genuine Oxycerites aspidoides ammonite fossil from the
Middle Jurassic, Upper Bajocian Stage, collected from Sengenthal, Bavaria, Germany. This carefully chosen fossil specimen has been selected for its natural fossil character, geological interest, and classic Jurassic display appeal. The photograph shows the actual specimen you will receive, so please refer to the photo for the full sizing, proportions, preservation, colour, matrix, surface texture, and overall condition of this individual fossil.This fossil is supplied with a Certificate of Authenticity lifetime guarantee generic card, giving confidence that the specimen is a genuine fossil and not a modern replica.SPECIES AND FOSSIL TYPEOxycerites aspidoides is an extinct ammonite species, a marine cephalopod that lived in ancient seas during the Jurassic Period. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, but they lived inside coiled, chambered shells. The living animal occupied the final outer body chamber, while the earlier internal chambers helped regulate buoyancy, allowing the ammonite to move through the water column.Oxycerites belongs to the ammonite order Ammonitida, and is associated with smooth to finely ornamented Middle Jurassic ammonites. This genus is particularly appreciated by collectors for its elegant shell form, compressed whorls, and refined appearance compared with more heavily ribbed Jurassic ammonites. Ammonites such as Oxycerites aspidoides are valued not only for their natural beauty but also for their scientific importance in understanding Middle Jurassic marine life.MIDDLE JURASSIC UPPER BAJOCIAN AGEThis fossil dates from the Upper Bajocian Stage of the Middle Jurassic, approximately 169 to 168 million years old. The Bajocian was an important interval in ammonite evolution, marked by diverse marine faunas and widespread shallow to moderately deep seas across Europe. During this time, ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, and other marine organisms lived in warm Jurassic waters.The Upper Bajocian is especially significant in ammonite biostratigraphy because many ammonite groups evolved rapidly. Their shell shapes, whorl profiles, ornamentation, and suture patterns help geologists compare and date Middle Jurassic rock layers. A fossil such as Oxycerites aspidoides is therefore an attractive collector specimen and a fascinating example of ancient marine palaeontology.SENGENTHAL AND BAVARIAN GEOLOGYThis specimen comes from Sengenthal in Bavaria, Germany, a locality known for fossil-bearing Jurassic sediments. During the Middle Jurassic, the region that is now Bavaria was very different from the modern landscape. Instead of dry land, it formed part of a marine environment connected to the wider European Jurassic seas.Sediments such as limestone, marl, clay-rich deposits, and carbonate mud accumulated on the sea floor, preserving the remains of ammonites and other marine animals. After death, ammonite shells could settle into soft sediment and become buried. Over millions of years, mineral-rich groundwater, pressure, and natural geological processes transformed these remains into fossils, while later erosion exposed the fossil-bearing layers.MORPHOLOGY AND NATURAL FEATURESOxycerites ammonites are known for their smooth, compressed, neatly coiled shell form. Unlike more strongly ribbed ammonites, Oxycerites often displays a cleaner, more streamlined appearance, with the beauty of the shell shown through its whorl shape, curvature, and overall symmetry. Important identification features in ammonites include shell compression, umbilicus width, whorl profile, chamber structure, suture pattern, and any visible ornamentation or growth lines.Depending on preservation, this specimen may show natural shell curvature, subtle growth features, chamber traces, mineralisation, matrix, colour variation, surface texture, or natural geological wear. These features are part of the fossil’s individual history and make each genuine ammonite unique. Please use the photograph to view the exact visible characteristics of this particular specimen, as the image shows the actual fossil supplied.ANCIENT JURASSIC MARINE LIFEDuring life, this Oxycerites aspidoides ammonite would have been part of a diverse Middle Jurassic marine ecosystem. Ammonites were active swimming cephalopods, using their chambered shells to regulate buoyancy and maintain stability in the water. They likely fed on small marine organisms or scavenged available food, while also forming part of the food chain for larger predators such as fish and marine reptiles.The shell was both protective and functional, allowing the animal to grow while keeping balance in the ancient sea. After the ammonite died, the shell settled onto the sea floor, became buried by sediment, and began the fossilisation process that preserved it for millions of years.COLLECTOR DISPLAY AND AUTHENTICITYThis Oxycerites aspidoides ammonite fossil from Sengenthal, Bavaria, Germany is ideal for fossil collectors, natural history enthusiasts, geology students, educational displays, cabinet collections, and anyone interested in genuine Jurassic fossils. It is especially suitable for collectors of ammonites, fossil cephalopods, German fossils, Middle Jurassic specimens, Upper Bajocian fossils, and ancient marine life.The fossil shown in the photograph is the actual specimen you will receive. Please check the photo carefully for full sizing and condition details, including any natural cracks, matrix, mineralisation, colour variation, preparation marks, surface wear, or other natural features.INCLUDED WITH THIS SPECIMENYour fossil will be supplied as a genuine specimen with a Certificate of Authenticity lifetime guarantee generic card. This makes it suitable for personal collecting, educational use, geology teaching, natural history display, or as a thoughtful gift for fossil lovers, palaeontology enthusiasts, students, teachers, and collectors of ancient marine specimens.
