Paroecotraustes prevalensis Ammonite Fossil Poland Bathonian with COA

Description

Genuine Paroecotraustes Ammonite Fossil

This genuine ammonite fossil is identified as Paroecotraustes prevalensis and comes from Wysoka, Poland. It dates to the Bathonian Stage of the Middle Jurassic and is a carefully selected European specimen with useful species, age, and locality information. The photographs show the actual fossil offered for sale, so the specimen pictured is the exact piece you will receive.

Paroecotraustes was an extinct marine cephalopod with a coiled, chambered shell. During growth, the animal added progressively larger chambers around the outer whorl. The living ammonite occupied the final body chamber, while the older sealed chambers helped regulate buoyancy. Although ammonites were related to living squid, cuttlefish, and nautiluses, they formed their own diverse and now-extinct group.

Bathonian Middle Jurassic Age

The Bathonian is a stage of the Middle Jurassic Period, approximately 168 to 166 million years ago. Marine environments covered broad areas of Europe during this interval and supported varied ammonite communities alongside bivalves, brachiopods, belemnites, and other sea life. After death, an ammonite shell could settle onto or become incorporated within sediment on the sea floor. Burial, compaction, mineral replacement, and geological change then preserved part of the shell as a fossil.

Ammonites evolved rapidly and were widely distributed through Jurassic seas. Their changing shell forms make them valuable index fossils, helping geologists compare rock layers and establish relative ages. The documented Bathonian age therefore gives this fossil a clear position within the Middle Jurassic succession.

Wysoka, Poland Provenance

Wysoka in Poland is known for Jurassic sedimentary rocks and fossil material that records the region’s ancient marine history. A specimen with documented locality information carries more scientific and collecting context than an entirely unlocalised fossil. It can complement a collection arranged by European country, Jurassic stage, ammonite genus, or palaeoenvironment.

Fine sediment deposited in the ancient sea helped protect portions of the shell and surrounding matrix. Natural colour, mineral texture, small breaks, areas of wear, and differences in surface preservation are part of the fossil’s long geological history. These individual characteristics distinguish a genuine specimen from a modern reproduction.

Shell Form and Collectable Detail

Paroecotraustes ammonites are collected for their recognisable coiled shell form and ornamentation. Examine the photographs for the visible whorls, rib pattern, shell outline, matrix, and preserved surface details on this particular specimen. Rib strength, whorl proportions, umbilical width, and changes in ornament around the shell are features used when comparing ammonites and understanding their growth.

Every fossil preserves a different balance of original shell, mineral replacement, and surrounding rock. The multiple images provide useful views of the exact piece and show its condition, proportions, natural texture, and display character more clearly than a generic photograph could.

Exact Specimen and Full Sizing

Full sizing is shown in the photographs, which provide the best scale information for this individual fossil. The images are not stock photographs and do not represent a similar example. They show the exact Paroecotraustes prevalensis ammonite fossil that will be supplied.

Authenticity and Presentation

This is a genuine fossil specimen and includes a generic Certificate of Authenticity card with a lifetime guarantee. It has been carefully chosen for its identifiable ammonite form, Bathonian age, Wysoka locality, Polish provenance, and natural geological character. It makes an appealing addition to a cabinet collection, educational display, office, study, or gift for anyone interested in authentic Middle Jurassic fossils, European palaeontology, or ammonite evolution.
