Description
Genuine Fontannesiella valentina Ammonite Fossil
This listing is for a genuine Fontannesiella valentina ammonite fossil from the Upper Jurassic, Kimmeridgian Stage, collected from Poránd, Zala, Hungary. This carefully chosen fossil specimen is an excellent piece for collectors of Jurassic ammonites, Hungarian fossils, fossil cephalopods, prehistoric marine life, natural history specimens, and educational geology displays.
The photograph shows the actual fossil specimen you will receive, so the colour, preservation, shape, surface detail, and natural character shown in the image belong to this individual piece. For full sizing and scale, please see the photo.
Fossil Type and Species Information
This fossil is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites are among the most iconic fossils of the Jurassic Period, recognised for their coiled shells, chambered internal structure, varied ornamentation, and major importance in dating ancient marine rock layers.
The species is Fontannesiella valentina, an Upper Jurassic ammonite associated with Kimmeridgian marine deposits. As an ammonite, this specimen represents the fossilised shell of a marine animal that lived in ancient seas more than 150 million years ago. The animal would have occupied the final outer body chamber, while the earlier internal chambers helped control buoyancy in the water column.
Depending on preservation, ammonites of this type may show planispiral coiling, whorl development, ribbing, shell sculpture, natural mineralisation, and surface texture. These features make ammonites highly collectable as both decorative display fossils and scientifically interesting specimens. The distinctive shell form records the growth of the animal during life and provides a direct link to the rich marine ecosystems of the Late Jurassic.
Upper Jurassic Kimmeridgian Age
This specimen dates from the Upper Jurassic Period, specifically the Kimmeridgian Stage, approximately 157 to 152 million years old. The Kimmeridgian was a significant interval in Late Jurassic marine history, when ammonites were widespread and diverse across many warm seas.
During this time, parts of Europe were covered by shallow to moderately deep marine environments. These seas supported ammonites, belemnites, bivalves, brachiopods, gastropods, crinoids, sponges, corals, fish, and marine reptiles. Ammonites such as Fontannesiella valentina lived within these ancient waters, using their chambered shells for buoyancy and movement.
After death, ammonite shells could sink to the sea floor and become buried in sediment. Over millions of years, mineralisation, pressure, and compaction preserved the shell as a fossil, creating a natural record of Jurassic marine life.
Poránd, Zala, Hungary Geological Locality
This ammonite comes from Poránd, Zala, Hungary, a locality with Upper Jurassic geological interest. Hungarian Jurassic fossils are appealing to collectors because they offer less commonly seen European locality data compared with more familiar fossil regions of France, Germany, and the United Kingdom. This makes the specimen a desirable addition for collectors building a geographically varied ammonite or Jurassic fossil collection.
The Zala region forms part of Hungary’s broader Mesozoic geological record, preserving evidence of ancient marine conditions that once existed across central Europe. Fossils from these deposits help illustrate the changing sea levels, sedimentary environments, and marine life of the Jurassic Period.
Natural Collector Display Specimen
This Fontannesiella valentina ammonite fossil is suitable for fossil collectors, geology students, teachers, natural history enthusiasts, and anyone interested in prehistoric marine life. It would display well in a fossil cabinet, educational teaching set, study collection, curiosity cabinet, or natural history-themed display.
A labelled fossil with species, age, geological stage, and locality information is far more useful than an unlabelled decorative ammonite. This specimen can be catalogued and displayed as a genuine Upper Jurassic Kimmeridgian ammonite from Hungary, making it suitable for both experienced collectors and new fossil enthusiasts.
As with all genuine fossils, the specimen may show natural features such as matrix, mineral staining, surface texture, small cracks, weathering, repaired areas, or variations in preservation. These characteristics are normal in authentic fossils and form part of the specimen’s geological history and natural appeal.
Certificate of Authenticity Included
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. This provides reassurance that the fossil supplied is authentic and suitable for collecting, study, gifting, display, resale, or educational use.
