Species and Fossil Type

Streblites tenuilobatus is an ammonite, an extinct marine mollusc related to modern squid, cuttlefish, and nautilus. Ammonites are among the most iconic fossils of the Jurassic seas, recognised for their coiled shells, chambered internal structure, and great value in dating sedimentary rock layers. The species name tenuilobatus is associated with fine, complex suture patterns and the refined shell form typical of many Upper Jurassic ammonite groups.

Streblites ammonites are generally valued for their elegant planispiral coiling and palaeontological significance. In life, the animal would have occupied the outer body chamber of the shell, while the inner chambers helped with buoyancy control in the water column. Like other ammonites, Streblites belonged to a highly successful group of marine cephalopods that flourished throughout the Jurassic before eventually becoming extinct at the end of the Cretaceous Period.

Geology and Age

This specimen dates from the Kimmeridgian Stage of the Upper Jurassic, approximately 157 to 152 million years ago. During this time, much of central Europe was covered by warm, shallow epicontinental seas. These marine environments supported a rich ecosystem of ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, marine reptiles, and other ancient sea life.

The Weißjura Gamma, also known as part of the White Jurassic succession in southern Germany, is an important limestone-rich interval within the Upper Jurassic. These pale carbonate deposits formed in ancient marine settings and are well known for preserving fossil ammonites and other marine organisms. The Kimmeridgian rocks of Germany are especially valued by collectors because they preserve a record of life from a period when ammonites were diverse and widespread across European seas.

Locality – Gersingen, Germany

Gersingen in Germany is associated with Jurassic strata that have produced collectable ammonites and other marine fossils. German Jurassic fossils are highly regarded among collectors for their geological provenance, attractive preservation, and connection to classic European stratigraphy. This Streblites tenuilobatus ammonite from Gersingen represents part of the rich fossil record preserved in the Upper Jurassic deposits of the region.

During the Kimmeridgian, the area that is now Germany was not dry land as it is today, but part of a shallow marine realm connected to broader Jurassic seas across Europe. Sediments accumulating on the sea floor gradually buried shells and skeletal remains, allowing some to fossilise through mineral replacement and long-term geological preservation.

Scientific and Collectable Interest

This Streblites tenuilobatus ammonite is a collectable Upper Jurassic fossil with strong display and educational appeal. Its named species, Kimmeridgian age, Weißjura Gamma geological context, and German locality make it suitable for a specialist fossil collection, natural history cabinet, educational geology set, museum-style display, or thoughtful gift for a fossil enthusiast.

Ammonites are especially popular because they combine natural beauty with scientific value. Their rapid evolution and wide distribution make them important index fossils for correlating Jurassic rock layers, while their coiled shell form gives them lasting visual appeal. This specimen offers a tangible connection to the ancient Jurassic seas of Germany, preserving the remains of a marine animal that lived millions of years before humans existed.
