Paraturrilites bergeri Heteromorph Fossil Ammonite Lower Cenomanian Cretaceous Drap France with COA

Description

Paraturrilites bergeri Heteromorph Ammonite from Drap, France

This is a Paraturrilites bergeri heteromorph fossil ammonite, discovered in Drap, France, from the Lower Cenomanian Stage of the Late Cretaceous Period. Dating to approximately 100–94 million years ago, this ammonite belongs to one of the most distinctive groups of heteromorph ammonites, whose unusual spiral shells diverged from the classic planispiral forms. Specimens such as this are both scientifically important and highly sought after by collectors for their rarity and striking morphology.

All of our specimens are 100% genuine fossils and are provided with a Certificate of Authenticity. The photographs show the exact fossil you will receive, with a 1cm scale cube and rule squares included for precise sizing.

Geological Age and Locality

The fossil comes from the Lower Cenomanian, the earliest stage of the Late Cretaceous. During this period, global sea levels rose dramatically, creating shallow marine environments across Europe that were rich in biodiversity. Ammonites flourished during this time, including heteromorph groups such as Paraturrilites, which represent some of the most unusual evolutionary experiments in cephalopod history.

The Drap locality in southern France is particularly well known for its Cenomanian deposits, which yield a variety of ammonites used in biostratigraphy. Fossils from this region are highly regarded for their preservation quality and their role in defining ammonite zones of the Cretaceous.

Fossil Type and Scientific Classification

• Genus: Paraturrilites
• Species: Paraturrilites bergeri
• Order: Ammonitida
• Superfamily: Turrilitoidea
• Family: Turrilitidae

Paraturrilites bergeri is a significant ammonite species used as an index fossil for Lower Cenomanian strata. Its distinctive morphology and well-defined stratigraphic range make it vital for correlating chalk and limestone deposits across Europe and beyond.

Morphological Features

The genus Paraturrilites is distinguished by its dramatic heteromorph form and ornate shell features. Key traits of P. bergeri include:

• Helicoidal Coiling: The shell grows in a vertical, turret-like spiral, departing from the traditional coiled ammonite form.
• Strong Ornamentation: Prominent ribs run across the flanks, producing a bold and sculptural surface.
• Tubercles: Distinct nodes or tubercles are often present along rib crests, adding to its characteristic appearance.
• Keel Presence: A keel runs along the venter, enhancing hydrodynamic structure and aiding identification.

These morphological features not only set Paraturrilites apart from other heteromorphs but also highlight its importance in ammonite taxonomy.

Scientific and Collector Importance

Paraturrilites bergeri holds great value in biostratigraphy, defining key ammonite zones within the Lower Cenomanian. Its restricted range and diagnostic features make it indispensable for geological correlation.

For collectors, fossils of Paraturrilites are rare and prized. With their unusual coiling and bold ornamentation, they provide a dramatic contrast to typical ammonites and represent some of the most fascinating evolutionary experiments of the Cretaceous seas. Specimens from Drap are especially desirable due to the site’s historical significance and the quality of preservation.

Display and Educational Value

This fossil has been carefully selected for its clear diagnostic features and overall preservation. Its tower-like spiral and ribbed shell form create a visually striking specimen that immediately captures attention.

Suitable for museum exhibits, private collections, or educational settings, this Paraturrilites bergeri ammonite from Drap, France provides both scientific significance and aesthetic appeal. It represents not only a remarkable chapter in ammonite evolution but also a tangible connection to the warm seas of the Cenomanian, when these extraordinary heteromorphs thrived.
