Rare Euphylloceras velledae Ammonite Fossil from Russia

This listing offers a rare Euphylloceras velledae ammonite fossil, dating from the Aptian stage of the Early Cretaceous period, discovered in Russia. This exceptional fossil is a scientifically important specimen that represents a unique stage in ammonite evolution, approximately 125–113 million years old. Each fossil is carefully photographed, with a 1 cm scale cube included for accurate sizing. The specimen shown in the images is the exact piece you will receive, and it comes with a Certificate of Authenticity, ensuring its genuine provenance and collector value.

Geological Context – Aptian Stage, Early Cretaceous

The Aptian stage of the Early Cretaceous was marked by significant marine transgressions and widespread shallow seas, which provided ideal conditions for ammonite diversification. In Russia, these deposits contain a rich fossil record, including both invertebrates and marine reptiles, offering a valuable window into life during this dynamic time.

Ammonites such as Euphylloceras velledae thrived in these marine environments, contributing to the biodiversity of the Cretaceous oceans. Their global distribution and distinct morphology also make them important index fossils for stratigraphic correlation, helping geologists date rock layers with high precision.

Species Overview – Euphylloceras velledae

The genus Euphylloceras is a member of the Order Ammonitida and the Family Phylloceratidae, known for its elegantly coiled and often ornamented shells. Euphylloceras velledae is a distinctive species with several notable features:

• A strongly involute shell, meaning the outer whorls envelop much of the inner coiling.
• Smooth to slightly ribbed flanks, with growth lines curving gently towards the aperture.
• A globular, inflated shape, giving it a robust but graceful appearance.
• Intricate suture patterns, typical of the Phylloceratidae, with highly complex lobes and saddles.

These morphological traits indicate that Euphylloceras velledae was a nektonic predator, actively swimming in the open ocean where it preyed upon smaller marine organisms.

Scientific and Collector Importance

Euphylloceras velledae holds a key role in Aptian biostratigraphy, with its distribution aiding researchers in refining the geological timescale. Its presence across multiple Cretaceous deposits demonstrates its adaptability and ecological importance.

For collectors, specimens of Euphylloceras velledae are highly sought after due to their rarity, excellent preservation, and aesthetic appeal. Fossils from Russian deposits are particularly valued for their scientific documentation and the distinct preservation style of the region.

Aesthetic and Educational Appeal

This ammonite fossil is not only of scientific value but also a fascinating natural display piece. The detail in the coiling, whorl structure, and suture lines makes it an excellent teaching example of ammonite evolution and morphology. Its rarity and provenance from Russia enhance its value as a centerpiece for both private and institutional collections.
