Description

Rare Proleymeriella schrammeni Ammonite Fossil

This listing offers a rare Proleymeriella schrammeni ammonite fossil, dating to the Lower Albian Stage of the Cretaceous period, collected in Hannover, Germany. This exceptional specimen highlights one of the more distinctive ammonite genera of the Early Cretaceous, notable for its ribbed ornamentation and importance in stratigraphy. The photographs display the exact fossil you will receive, with a 1 cm cube included for accurate size reference. As always, this is a 100% genuine fossil specimen and comes complete with a Certificate of Authenticity.

Geological Age and Context

The Albian Stage (approximately 113–100.5 million years ago) marks the final stage of the Early Cretaceous. During this period, extensive shallow seas covered much of Europe, including northern Germany, creating rich marine environments ideal for the preservation of ammonites. The Lower Albian deposits of Hannover are among the most significant fossil-bearing strata in Europe, preserving diverse ammonite faunas alongside other marine invertebrates. These sediments, largely composed of claystones and marls, reflect deposition in a shallow epicontinental sea that stretched across much of central Europe. Fossils from Hannover are highly regarded for their scientific value and historical significance in the study of Cretaceous paleontology.

Taxonomy and Classification

Proleymeriella schrammeni belongs to the genus Proleymeriella, within the family Lyelliceratidae, superfamily Acanthoceratoidea, and order Ammonitida. Members of this group are characterised by their strong ribbing and compact, robust shells, making them easily identifiable among Albian ammonites. The species schrammeni is a key taxon in the Lower Albian, often used in stratigraphic studies as a zonal ammonite. Its distribution and clear diagnostic traits make it a valuable reference point for both research and private collections.

Morphological Features

The shell of Proleymeriella schrammeni is compact and sturdy, with prominent ribs radiating across the flanks and often curving slightly toward the venter. These ribs give the ammonite its distinctive ornamentation and structural strength. The whorls are moderately involute, with later coils partly enveloping earlier ones, forming a balanced and symmetrical shell. The venter is broad, with ribs crossing continuously, producing a striking sculptural effect. These features not only make the fossil scientifically important but also give it strong visual appeal as a display specimen.

Scientific and Collector Importance

Ammonites such as Proleymeriella schrammeni are highly significant in biostratigraphy of the Lower Albian. Their relatively narrow stratigraphic range and distinctive morphology allow geologists to correlate Albian deposits across Europe and beyond. For collectors, this species holds special value as an uncommon fossil from a historic German locality. Specimens from Hannover are increasingly difficult to obtain, making this example a particularly desirable acquisition for any serious collector of ammonites or Cretaceous fossils.

Provenance and Authenticity

This ammonite fossil was collected in Hannover, Germany, one of the classic European fossil localities for Albian ammonites. Each specimen we offer is carefully chosen for its quality and authenticity. Every fossil is supplied with a Certificate of Authenticity, and secure professional packaging ensures safe delivery so your specimen arrives in excellent condition.

This is a rare Proleymeriella schrammeni ammonite fossil from the Lower Albian of Hannover, Germany. With its bold ribbing, excellent preservation, and scientific significance, it is a superb addition to any ammonite, Cretaceous fossil, or natural history collection.
