This listing offers a genuine Thomelites fossil ammonite from the Santonian stage of the Late Cretaceous, discovered in Charente, France. Formed approximately 86–83 million years ago, this specimen provides a direct glimpse into the marine ecosystems that thrived in Europe during the height of the Cretaceous Period. The ammonite has been carefully selected for its preservation and aesthetic appeal and comes complete with a Certificate of Authenticity. The photographs display the exact fossil you will receive, and a 1 cm scale cube is included to provide accurate sizing.

Geological Context – The Santonian Stage

The Santonian stage is part of the Upper Cretaceous, a time characterised by globally high sea levels and widespread shallow seas. These conditions were perfect for ammonites such as Thomelites, which flourished in warm marine environments alongside other molluscs, crustaceans, and marine reptiles.

Charente, located in western France, is particularly well known for its fossiliferous deposits from the Cretaceous, offering rich insights into marine biodiversity. Sedimentary layers from this region often preserve marine fossils in fine detail, making them highly prized by collectors and researchers alike.

Species Profile – Thomelites

Thomelites belongs to the order Ammonitida, within the superfamily Desmoceratoidea. This group is noted for its evolutionary diversity and distinctive shell ornamentation during the Late Cretaceous.

Key features of Thomelites ammonites include:

• Shell Coiling: Involute coiling with overlapping whorls that produce a compact shape.
• Ornamentation: Fine ribbing across the flanks and growth lines along the shell, often giving a textured appearance.
• Morphology: Smooth to slightly ribbed venter with well-defined sutures, helping paleontologists identify the genus.
• Adaptations: Likely pelagic predators, using their buoyant shells to regulate depth while hunting for small marine prey such as crustaceans and fish.

The genus Thomelites plays an important role as a biostratigraphic marker in the Santonian, allowing scientists to correlate marine sediments across Europe and beyond.

Scientific and Educational Value

As a stratigraphically significant ammonite, Thomelites provides key information about marine environments during the Santonian stage. Fossils such as this help paleontologists reconstruct ancient ecosystems, track evolutionary changes, and refine geological timelines. The excellent preservation of ammonites from Charente also offers insight into shell morphology and growth patterns, making them valuable for academic study.

For collectors, this fossil represents not only a beautiful natural specimen but also a scientifically important relic of Earth’s history. Its rarity outside of specialist collections makes it especially appealing for display or research purposes.
