Description
Offering a RARE specimen of Lytoceras salebrosum, a beautifully preserved ammonite fossil from the Upper Pliensbachian stage of the Early Jurassic period, found in the Calvados region of Normandy, France—a classic locality known for its rich marine fossil assemblages.
The genus Lytoceras is part of the family Lytoceratidae, known for its highly evolute shell with simple, undivided, sinuous ribbing and smooth ornamentation. The species salebrosum typically features broad whorls and pronounced growth lines, with a shell morphology that suggests a fast-moving, nektonic lifestyle in open marine settings.
This particular fossil has been carefully selected for its scientific and aesthetic value and is presented exactly as shown in the photographs. The scale cube with 1cm squares provides a clear and accurate size reference. As always, all our fossils are 100% genuine and come with a Certificate of Authenticity.
Geological & Scientific Information:
- Species: Lytoceras salebrosum
- Type: Fossil Ammonite (extinct marine cephalopod mollusc)
- Geological Period: Jurassic
- Stage: Upper Pliensbachian (approx. 190 to 183 million years ago)
- Location Found: Calvados, Normandy, France
- Order: Ammonitida
- Superfamily: Lytocerataceae
- Family: Lytoceratidae
- Morphological Features: Evolute, discoidal shell with broad whorls; fine, sinuous growth lines; low ornamentation; wide umbilicus; smooth surface texture
- Biozone (if applicable): Commonly associated with the Spinatum Zone, used for biostratigraphic dating within the Upper Pliensbachian
- Depositional Environment: Offshore marine setting, likely from deep subtidal carbonate muds deposited in the developing Paris Basin
- Scientific Importance: Lytoceras is often used as an indicator of open marine conditions and holds value in understanding Jurassic palaeoecology and ammonite evolutionary trends
Additional Notes:
This is a particularly fine example of Lytoceras salebrosum, showcasing the elegance and simplicity of lytoceratid ornamentation. A fantastic piece for fossil collectors, academic collections, or natural history enthusiasts.
