Fossil Type and Species

Androgynoceras capricornum is an extinct ammonite, a marine cephalopod related to modern squid, octopus, and cuttlefish. Ammonites lived in coiled shells divided into chambers, using their chambered shell structure to help control buoyancy in ancient seas. After death, the empty shells often settled onto the sea floor, where they could become buried in sediment and preserved through fossilisation over millions of years.

Androgynoceras is part of the ammonite group often associated with the Lower Pliensbachian of the Early Jurassic. The species capricornum is linked with the classic capricorn ammonite forms known from this interval. Ammonites from this period are highly valued by collectors because they are not only attractive fossils but also important tools in geology. Their rapid evolution and wide distribution make them useful for dating and correlating Jurassic rock layers.

Geological Age and Pliensbachian Setting

This ammonite dates from the Lower Jurassic Period, specifically the Lower Pliensbachian Stage, making it approximately 190 million years old. During the Early Jurassic, much of what is now southern and western Britain was covered by shallow marine environments. These warm Jurassic seas supported a wide range of life, including ammonites, bivalves, belemnites, fish, and marine reptiles.

The sediments that preserved fossils such as this Androgynoceras capricornum were deposited on ancient sea floors. Fine muds, silts, and calcareous marine deposits gradually buried shells and organic remains, protecting them from destruction and allowing mineralisation to take place. Over geological time, pressure, chemistry, and burial transformed these remains into the fossil specimens collected from classic Jurassic exposures today.

Radstock, Somerset Fossil Locality

Radstock, Somerset is a well-known British fossil locality associated with Lower Jurassic strata. Fossils from this area are popular with collectors because they represent part of the United Kingdom’s rich Jurassic marine fossil record. Ammonites from Radstock are particularly desirable for fossil collections, educational displays, natural history cabinets, and anyone interested in British geology.

Somerset’s Jurassic rocks preserve evidence of ancient marine ecosystems that existed long before modern Britain took shape. A fossil from this locality is not just a decorative specimen; it is a genuine piece of geological history from an ancient sea that covered the region during the Early Jurassic.

Shell Form and Natural Features

Androgynoceras ammonites are known for their coiled shell form and ribbed ornamentation. The shell would originally have grown in a spiral, with new chambers added as the animal matured. The visible ribs and natural curves seen on many ammonites helped strengthen the shell and are key features used in ammonite identification.

As a genuine fossil, this specimen may display natural characteristics such as mineral staining, matrix attachment, ancient surface wear, minor chips, weathered areas, compression, or partial preservation. These are normal features of authentic fossil material and reflect the specimen’s long geological history. Each fossil is unique, and the photograph shows the exact piece being offered.

Collectable Jurassic Display Specimen

This Androgynoceras capricornum ammonite fossil is ideal for fossil collectors, geology students, educational collections, natural history displays, school teaching resources, or anyone looking for a genuine Lower Jurassic ammonite from a classic UK locality. Its combination of scientific interest, British provenance, and attractive ammonite form makes it a strong addition to any fossil collection.

The specimen comes exactly as shown in the photo and includes a Certificate of Authenticity lifetime guarantee generic card, making it a reliable and well-presented choice for collectors of ammonites, Jurassic fossils, Somerset fossils, and genuine natural history specimens.
