Description
Genuine Parachoffatia cf. subbakeriae Ammonite Fossil
This listing is for a genuine Parachoffatia cf. subbakeriae ammonite fossil from La Motte Bourbon, Vienne, France, dating to the Middle Jurassic, Callovian stage. This carefully chosen fossil is an authentic natural specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The photograph shows the actual fossil you will receive, so the piece pictured is the exact specimen supplied. Full sizing details can be seen in the photo.
This is an excellent fossil for collectors of Jurassic ammonites, French fossils, marine cephalopods, prehistoric sea life, natural history specimens, and educational geology displays. With its Middle Jurassic age and European locality, this ammonite represents a genuine piece of ancient marine history from the warm seas that once covered parts of what is now France.
Fossil Type and Species
Parachoffatia cf. subbakeriae is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites had coiled, chambered shells, with the living animal occupying the outer body chamber. The inner chambers helped regulate buoyancy, allowing the ammonite to move through the water column of ancient seas.
The use of “cf.” in the name indicates that the specimen compares closely with Parachoffatia subbakeriae. This is a common and careful palaeontological way of presenting fossils where the identification is strongly comparable to a named species. Parachoffatia is a Jurassic ammonite genus associated with perisphinctid ammonites, a group well known for their coiled shells, ribbed ornamentation, and importance in Middle Jurassic biostratigraphy.
Middle Jurassic Callovian Age
This fossil dates to the Callovian stage of the Middle Jurassic Period. The Callovian was a time of active marine life, warm shallow seas, and widespread sediment deposition across parts of Europe. Ammonites were especially diverse during this interval and are highly important to geologists because their rapid evolution and broad distribution make them excellent fossils for dating and correlating rock layers.
During the Callovian, ancient seas supported a rich range of organisms including ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, crinoids, fish, and marine reptiles. Ammonites such as Parachoffatia formed part of this marine ecosystem, living as active swimming or drifting cephalopods before their shells settled onto the sea floor after death and became buried in sediment.
La Motte Bourbon, Vienne, France Locality
This specimen comes from La Motte Bourbon in Vienne, France. Fossils from French Jurassic deposits are highly collectable because they represent classic European marine geology and preserve evidence of the extensive seas that covered the region during the Mesozoic Era. The Vienne area lies within a broader region of sedimentary rocks that record changing Jurassic sea levels, marine habitats, and fossil-rich depositional environments.
The sediments that preserved ammonites from this region were laid down in marine conditions where shells and skeletal remains could accumulate, become buried, and gradually mineralise over millions of years. These deposits provide a valuable record of ancient sea-floor environments and the organisms that lived in them.
Morphology and Collectable Features
Parachoffatia ammonites are generally appreciated for their classic Jurassic ammonite form, often with a coiled shell, visible whorl structure, and ribbed ornamentation. Depending on preservation, specimens may display curved ribs, a defined umbilicus, natural shell texture, mineralised detail, and surrounding matrix from the original rock. These features give the fossil both decorative appeal and palaeontological interest.
Perisphinctid-style ammonites are often particularly attractive to collectors because of their strong ribbing and balanced spiral form. The ribs record growth and shell structure, while the overall coiling reflects the elegant geometry that makes ammonites among the most recognisable fossils in the world.
Authenticity and Display Appeal
As a genuine natural fossil, this specimen may show normal signs of age and preservation, including surface texture, mineral replacement, matrix attachment, small chips, repairs, weathering, compression, or natural colour variation. These are typical features of authentic fossils and form part of the individual character of the piece. This is not a modern replica, cast, or decorative imitation.
