Description
Pseudobradia lehmanni Ammonite Fossil
This genuine Pseudobradia lehmanni ammonite fossil is a collectible Lower Jurassic marine specimen from Vendée, Pays de la Loire, France. Dating to the Upper Toarcian stage, this fossil represents an interesting and less commonly encountered ammonite from the ancient Jurassic seas of western France. With its clear species identification, French locality and Lower Jurassic age, this specimen is an excellent addition to a fossil collection, natural history display, educational geology cabinet or ammonite collection.
The specimen is a carefully chosen piece, with the photograph showing the actual fossil you will receive. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it ideal for collectors who value genuine fossils with clear provenance.
Geology, Age and Locality
This fossil comes from the Upper Toarcian of the Lower Jurassic, an interval dating to approximately 174 to 182 million years ago. The Toarcian was a significant stage in Jurassic marine history, known for widespread shallow to moderately deep seas across much of Europe and for its diverse ammonite faunas. Ammonites from this period are especially important because their rapid evolution makes them valuable guide fossils for dating and correlating rock layers.
The Vendée region of Pays de la Loire, France contains Jurassic marine deposits that record ancient environments once connected to the wider European and Tethyan seaways. During the Early Jurassic, this area was influenced by warm marine conditions where fine sediment accumulated on the seabed. Ammonite shells, belemnites, bivalves and other marine remains could become buried in these sediments and preserved over millions of years as fossils.
French Jurassic fossils are highly regarded by collectors because they combine classic European geological provenance with attractive palaeontological interest. A labelled ammonite from Vendée is particularly desirable for collectors building a collection of French fossils, Lower Jurassic ammonites or Toarcian marine specimens.
Fossil Type and Species Details
Pseudobradia lehmanni is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish and nautilus. Ammonites lived inside coiled external shells divided into internal chambers. The living animal occupied the final body chamber, while the empty chambers helped regulate buoyancy as it moved through the water column.
The genus Pseudobradia is associated with Toarcian ammonite faunas and is valued for its role within Lower Jurassic biostratigraphy. Specimens of this type typically show the coiled shell form and ribbed ornamentation characteristic of many Jurassic ammonites. These features were not only visually distinctive, but also helped strengthen the shell and are important in fossil identification.
Pseudobradia lehmanni belongs to the order Ammonitida, a major group of Mesozoic ammonites that flourished throughout the Jurassic and Cretaceous. Ammonites from the Toarcian are especially useful to palaeontologists because different species can be linked to relatively narrow intervals of geological time, helping to date marine sediments with precision.
Upper Toarcian Marine Environment
When this ammonite was alive, the region that is now western France was part of a Jurassic marine environment rich in life. Ammonites such as Pseudobradia lehmanni were active swimming cephalopods, moving through the water alongside belemnites, fish and other marine animals. The seabed supported communities of bivalves, brachiopods, gastropods, crinoids and other invertebrates adapted to the changing conditions of the Jurassic sea.
The ammonite shell was both protective and functional. Its chambered internal structure helped with buoyancy control, while the external shell shape and ornamentation contributed to strength and movement through the water. Today, these same features make ammonites among the most recognisable and popular fossils, combining natural beauty with scientific importance.
Vendée, Pays de la Loire, France
Vendée in Pays de la Loire, France provides strong locality provenance for this fossil. Specimens from named regions are especially valued because they preserve not only the fossil itself, but also its geological and geographical context. Clear locality information makes a fossil more meaningful for collectors, students and anyone interested in Earth history.
This Pseudobradia lehmanni ammonite from Vendée is suitable for display, study, teaching or adding to a themed collection of French fossils, Lower Jurassic marine life or Toarcian ammonites. Its combination of named species, Upper Toarcian age and French provenance gives it strong collecting appeal.
