Geological Age and Locality – The Lower Albian of Hannover

The Lower Albian stage is an important division of the Early Cretaceous, representing a time of major marine transgressions across Europe. Hannover is among the most celebrated localities for Albian ammonites, yielding beautifully preserved fossils that have been studied by paleontologists for over a century. These strata belong to the Lower Cretaceous marine sequences of northern Germany, formed in shallow epicontinental seas that covered much of Europe during this time.

Ammonites such as Proleymeriella schrammeni are critical index fossils for biostratigraphy. Their rapid evolutionary changes and wide distribution allow geologists to precisely date and correlate rock layers across different regions, making them invaluable to both science and collectors alike.

Morphological Features of Proleymeriella schrammeni

This specimen of Proleymeriella schrammeni exhibits all the classic characteristics associated with the genus:

• Coiling: Evolute shell form with whorls that are exposed and well defined.
• Ornamentation: Fine, regular ribs running across the whorls, often gently curved, adding delicate texture to the shell.
• Whorl Shape: Compressed lateral profile, giving the shell a streamlined appearance.
• Sutures: Complex suture patterns visible in parts of the fossil, showcasing the intricate natural design of ammonites.
• Preservation: Well-preserved surface detail, capturing the natural morphology of this Lower Albian ammonite.

These features not only allow precise identification of the species but also add to the visual appeal, making the fossil suitable for both academic study and display.

Paleontological Importance

Proleymeriella schrammeni is significant in paleontology for its role in defining parts of the Lower Albian ammonite zones. As part of the Leymeriellidae family, it is closely related to other ammonites that are essential for dividing the Albian stage into smaller biostratigraphic intervals. Its presence in Hannover’s deposits has helped refine the understanding of marine faunal succession during the Early Cretaceous.

In life, ammonites were active marine cephalopods, related to modern squid and cuttlefish. Their role in the marine food chain as predators of smaller animals makes their fossils crucial to reconstructing the ecosystems of the Early Cretaceous seas.

Depositional Environment of Hannover

The Hannover deposits where this ammonite was found represent shallow marine conditions, with alternating sandy and clay-rich sediments. These environments were ideal for the preservation of ammonite shells, which were often quickly buried by fine sediments, protecting them from erosion and allowing exceptional fossilisation. Fossils from this locality have been prized for their scientific and historical importance, as well as their aesthetic quality.

Collector Appeal and Display

This Proleymeriella schrammeni ammonite fossil is not only scientifically valuable but also highly collectible. Its distinctive morphology, rarity, and provenance from the classic fossil-rich region of Hannover make it a prized specimen for both beginner and advanced fossil collectors.

The fossil is supplied with a Certificate of Authenticity, and the photographs include a 1 cm scale cube to provide accurate sizing. The actual specimen in the photo is the one you will receive, ensuring transparency and trust in what is offered. It is an ideal piece for display in a collection, a teaching setting, or as a natural history showcase item.
