Description
Genuine Clambites hypselus Ammonite Fossil from Gräfenberg, Bavaria
A genuine Clambites hypselus ammonite fossil from Gräfenberg, Bavaria, Germany, dating to the Upper Jurassic, specifically the Lower Kimmeridgian, Malm Alpha. This carefully chosen fossil represents an attractive European Jurassic ammonite from a classic German fossil region, preserved from marine sediments laid down during one of the most important intervals of Late Jurassic ammonite evolution.
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. Full sizing can be seen in the photo, and the fossil shown is the actual specimen you will receive. It is a desirable piece for ammonite collectors, Jurassic fossil enthusiasts, German fossil specialists, educational displays, natural history cabinets, and anyone interested in accurately labelled prehistoric marine life.
Fossil Type and Species Information
Clambites hypselus is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, and nautilus. Ammonites lived in ancient seas and possessed coiled, chambered shells. The living animal occupied the final body chamber, while the inner chambers helped control buoyancy as the animal moved through the water column.
This species belongs to the wider ammonoid group that flourished throughout the Jurassic Period. Ammonites are among the most important fossils in palaeontology because they evolved rapidly, spread widely through ancient seas, and left behind distinctive shell forms that allow geologists to date rock layers with precision. A named species such as Clambites hypselus gives the specimen strong scientific and collector appeal.
Depending on preservation, Clambites hypselus may show a compact coiled shell, defined whorl structure, ribbing, curved growth features, and the natural symmetry typical of Jurassic ammonites. These details make the fossil visually appealing while also preserving the architecture of a marine animal that lived millions of years before humans appeared.
Upper Jurassic Lower Kimmeridgian Age
This specimen comes from the Lower Kimmeridgian stage of the Upper Jurassic, approximately 155 million years old. The Kimmeridgian was a time of widespread shallow marine environments across Europe, with warm seas supporting a rich diversity of ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, and marine reptiles.
The term Malm Alpha is used in German Jurassic stratigraphy and refers to part of the lower Malm succession. The Malm represents the Upper Jurassic rock sequence in southern Germany and is famous for producing a wide range of marine fossils. Fossils from these beds are valued because they come from well-studied geological successions with a long history of palaeontological research.
Gräfenberg and Bavarian Geological Context
Gräfenberg, in Bavaria, Germany, lies within a region known for Jurassic marine strata and fossil-bearing limestone and marl deposits. During the Late Jurassic, this area formed part of a warm European sea with carbonate-rich sedimentation. Shells, skeletal remains, and organic material accumulated on the seabed, later becoming compacted and mineralised into the fossils found today.
Bavarian Jurassic fossils are popular with collectors because they often combine strong preservation, classic European geology, and accurate stratigraphic context. A specimen from Gräfenberg with a Lower Kimmeridgian, Malm Alpha attribution is particularly appealing for collectors building a geographically and stratigraphically detailed ammonite collection.
Ancient Marine Environment
Clambites hypselus lived in a Late Jurassic marine environment where ammonites were active swimming cephalopods. They shared the sea with belemnites, fish, marine reptiles, shelled invertebrates, and many seabed-dwelling organisms. The ammonite’s chambered shell allowed buoyancy control, while its soft body would have extended from the outer chamber.
After death, the shell settled onto the seabed. If it was quickly buried by sediment, it could be protected from destruction and preserved through fossilisation. Over millions of years, mineral-rich water and geological pressure transformed the buried remains into stone, preserving the fossil as a natural record of Jurassic marine life.
Morphology and Collector Appeal
Clambites hypselus is an attractive ammonite for display because of its named species identification, Upper Jurassic age, German provenance, and Lower Kimmeridgian stratigraphic placement. The fossil may display natural whorl shape, shell curvature, ribbing, and surface detail, all of which add visual interest and scientific value.
This specimen would make an excellent addition to a fossil cabinet, desk display, teaching collection, museum-style arrangement, or European Jurassic fossil collection. Its combination of locality, age, and species information makes it suitable for both new collectors and experienced fossil enthusiasts who appreciate well-labelled ammonites.
