It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it an excellent choice for collectors of French fossils, Lower Jurassic ammonites, natural history specimens and educational geology displays.
Geology, Age and Locality
This ammonite comes from the Upper Toarcian of the Lower Jurassic, an interval dating to approximately 174 to 182 million years ago. The Toarcian was an important stage in Jurassic marine history, marked by widespread shallow to moderately deep seas across Europe and a rich diversity of ammonites. These rapidly evolving cephalopods are especially useful to palaeontologists because they help date and correlate rock layers with great precision.
The locality of Rouffiac in Lozère, France lies within a region well known for Jurassic sedimentary rocks and marine fossil assemblages. During the Early Jurassic, this part of southern France formed part of a warm marine environment connected to the western Tethys realm. Fine muds, silts and carbonate-rich sediments accumulated on the seabed, burying ammonite shells and other marine remains before they could be broken down. Over millions of years, these sediments hardened into fossil-bearing rock, preserving specimens such as this Podagrosites ammonite.
Fossil Type and Species Details
Podagrosites aff. latescens pseudogrunowi 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 animal occupied the final body chamber, while the empty chambers helped control buoyancy as it moved through the water column.
The use of aff. means the specimen shows close affinity to the named form, making it especially interesting for collectors who appreciate fossil variation and careful palaeontological identification. Ammonites from this group are typically valued for their coiled shell form, ribbed ornament and importance within Toarcian ammonite faunas.
Podagrosites is associated with the order Ammonitida, a major group of Mesozoic ammonites that flourished throughout the Jurassic and Cretaceous. Toarcian ammonites are particularly important in biostratigraphy because their shell forms changed quickly over geological time, allowing them to act as guide fossils for specific horizons within the Lower Jurassic.
Upper Toarcian Marine Environment
When this ammonite was alive, the region now known as Lozère was covered by a Jurassic sea rich in marine life. Ammonites such as Podagrosites were active swimming animals, moving through the water alongside belemnites, fish and other nektonic organisms. On the seabed, bivalves, brachiopods, gastropods, crinoids and other invertebrates inhabited the soft sediment and harder shell-rich areas.
The ammonite shell was both protective and functional. Its chambered structure allowed the animal to regulate buoyancy, while the shell’s coiling and ornamentation gave strength and helped define the species. These natural features make ammonites one of the most popular fossil groups for collectors, combining visual appeal with genuine geological significance.
Rouffiac, Lozère, France
Rouffiac in Lozère, France is a desirable locality reference for collectors of European Jurassic fossils. Fossils from named localities are especially valued because they preserve not only the specimen itself, but also its geological and geographical provenance. A labelled ammonite from Rouffiac offers a direct connection to the Lower Jurassic marine history of southern France.
This Podagrosites aff. latescens pseudogrunowi ammonite from Rouffiac is suitable for display, study, teaching or adding to a themed collection of French fossils, Jurassic ammonites or Toarcian marine specimens. Its combination of Upper Toarcian age, detailed identification and clear locality makes it a distinctive and appealing fossil for collectors.
