Collignoniceras Fossil Ammonite Lower Turonian Cretaceous Soria Burgos Spain with Certificate of Authenticity

Description

Genuine Collignoniceras Fossil Ammonite

This listing is for an authentic Collignoniceras fossil ammonite from the Lower Turonian Stage of the Cretaceous Period, dating to approximately 93–90 million years ago. It originates from the renowned fossil-rich deposits of Soria and Burgos, Spain, an area that has yielded some of the most scientifically valuable ammonites in Europe. Each specimen is carefully chosen for its scientific importance, aesthetic appeal, and preservation quality, and comes with a Certificate of Authenticity, guaranteeing its 100% genuine origin. The specimen shown is the exact fossil you will receive, photographed alongside a 1 cm scale cube and rule for accurate sizing reference.

Geological Context

The Lower Turonian represents a key interval of the Late Cretaceous when global sea levels were exceptionally high, creating vast shallow marine environments across much of Europe. The Iberian Peninsula, including the provinces of Soria and Burgos, was submerged beneath these warm seas, allowing diverse marine life to flourish. Ammonites such as Collignoniceras are excellent index fossils, meaning they are used by geologists and paleontologists to precisely date and correlate sedimentary strata across wide regions.

The Spanish deposits where this ammonite was discovered are composed of limestones and marls that preserve exceptional detail of the original shells, making them highly valuable for both collectors and researchers.

Scientific Classification

• Genus: Collignoniceras
• Order: Ammonitida
• Superfamily: Acanthocerataceae
• Family: Collignoniceratidae
• Geological Stage: Lower Turonian, Cretaceous
• Provenance: Soria and Burgos, Spain

Members of the genus Collignoniceras are considered key biostratigraphic markers for the Lower Turonian and are important in defining ammonite zones used throughout Europe and North Africa.

Morphological Features

The Collignoniceras ammonite is characterized by:

• A strongly ornamented shell with pronounced ribbing running across the flanks and ventral area.
• Tubercles and nodes along the ribs, a diagnostic feature of this genus.
• A moderately compressed whorl section that highlights its adaptation to open marine habitats.
• A complex suture line pattern, visible in well-preserved specimens, which provides crucial taxonomic information.

These morphological traits not only make the fossil scientifically valuable but also aesthetically striking, making it a perfect centerpiece for any collection.

Scientific and Collector Importance

Ammonites such as Collignoniceras are essential to the study of the Cretaceous Period because they evolved rapidly and were widely distributed, allowing precise biostratigraphic correlations. Collectors value them for their rarity, historical significance, and beauty. Specimens from Spain are particularly desirable, as they are less commonly found on the market compared to those from Morocco or France.

This fossil is an excellent acquisition for collectors, educators, and researchers alike. Its rarity and well-defined features ensure that it is both a scientifically informative piece and a display-worthy specimen.

Display and Educational Value

This ammonite is ideal for museum displays, educational collections, or private fossil enthusiasts seeking to expand their holdings with a scientifically important specimen. Its preservation provides a window into the marine ecosystems of the Turonian seas, illustrating the incredible diversity of ammonites during the Late Cretaceous.

Owning this Collignoniceras fossil ammonite from Soria and Burgos, Spain not only adds a remarkable piece to your collection but also connects you directly to Earth’s deep history, over 90 million years in the making.
