Hammatoceras jurense Ammonite Fossil – Upper Toarcian Jurassic France, Authentic Specimen
£ 48.00
A finely preserved specimen of Hammatoceras jurense, a coiled fossil ammonite
from the Upper Toarcian Stage of the Early Jurassic, approximately 180 million years old. This ammonite was collected in France, a region well-known for its exceptional fossiliferous strata from this geological stage.Hammatoceras is easily identified by its strongly ribbed, planispirally coiled shell and well-developed keel, with H. jurense representing one of the classic species used for biostratigraphic correlation in the Toarcian.Fossil Type: Ammonite (extinct marine cephalopod)Species: Hammatoceras jurenseGeological Age: Lower Jurassic – Upper Toarcian StageFormation: Likely part of the Toarcian clay-limestone sequences common in northern and central FranceDepositional Environment: Formed in a calm, offshore marine basin under low-oxygen conditions. These sedimentary environments favoured preservation of cephalopods and other marine invertebrates in fine-grained limestone or marl.Morphological Features:
• Strongly ribbed shell with prominent radial ribs
• Planispiral coiling with an open umbilicus
• Distinct keel running along the venter
• May show partial preservation of original shell material or infillNotable:
• Key zone fossil for the Upper Toarcian of Europe
• Collected from a classic French Jurassic locality
• Ideal for collectors, educators, and display
• Actual specimen shown in the listing photographAuthenticity: All of our fossils are 100% genuine natural specimens and are supplied with a Certificate of Authenticity. The image includes a 1cm scale rule or cube for accurate sizing. This Hammatoceras jurense fossil offers a striking example of Early Jurassic ammonites, combining scientific significance with elegant natural form. A must-have for fossil enthusiasts and collectors alike.
