Description
A beautiful and rare example of Lytoceras adeloides, a distinctive ammonite fossil from the Pliensbachian Stage of the Lower Jurassic, approximately 190–192 million years ago. This specimen was collected from classic Jurassic deposits in Italy, a region known for its high-quality marine fossils.
Lytoceras ammonites are recognised for their smooth, involute coiling and finely ribbed or even nearly smooth shells, with wide umbilici and complex suture lines. L. adeloides is a rare and elegant representative of this genus and is especially sought after by collectors for its aesthetic structure and scientific interest.
Fossil Type: Ammonite (extinct marine cephalopod)
Species: Lytoceras adeloides
Geological Age: Lower Jurassic – Pliensbachian Stage
Formation: Likely part of Pliensbachian marine limestone or marl deposits of northern or central Italy
Depositional Environment: These ammonites lived in open marine environments, often deeper shelf settings, where sediments accumulated slowly. Preservation is generally excellent due to fine sediment and low disturbance.
Morphological Features:
- Smooth, evolute shell with faint or absent ribbing
- Wide umbilicus
- Complex suture lines characteristic of Lytoceras
- Coiling generally open and symmetrical
Notable:
- Rare species from the Lytoceratidae family
- Elegant appearance, ideal for fossil displays or academic collections
- Sourced from Jurassic fossil beds of Italy
- The specimen shown is the exact one you will receive
Authenticity: All of our fossils are 100% genuine natural specimens and come with a Certificate of Authenticity. Please refer to the included scale cube or ruler (1cm per square) for exact sizing.
This rare Lytoceras adeloides ammonite from the Pliensbachian of Italy is a fine example of early Jurassic cephalopods—elegant, scientifically relevant, and ideal for collectors seeking something special.
