Rare Hoplites Ammonite Fossil Middle Albian Cretaceous Troyes France Genuine Authentic Certified Specimen

Description

Rare Hoplites Ammonite Fossil

This listing presents a rare Hoplites ammonite fossil from the Middle Albian Stage of the Cretaceous period, collected near Troyes, France. The specimen demonstrates the ribbing and coiling typical of this iconic genus and is a fine example from a locality well known for its Cretaceous marine fossils. The photos provided show the exact fossil you will receive, with a 1 cm cube for accurate size reference. As always, this is a 100% genuine fossil specimen supplied with a Certificate of Authenticity.

Geological Age and Context

The Albian Stage (approximately 113–100.5 million years ago) represents the final interval of the Early Cretaceous. During this time, large areas of Europe were submerged beneath warm shallow seas connected to the Tethys Ocean. The deposits around Troyes in northern France are rich in marine clays and limestones that preserve a variety of marine organisms, particularly ammonites. Ammonites of the genus Hoplites are especially significant from this stage, serving as index fossils that allow geologists to correlate rock layers across Europe with remarkable precision.

Taxonomy and Classification

This specimen belongs to the genus Hoplites, within the family Hoplitidae, superfamily Hoplitaceae, and order Ammonitida. Members of this group are characterized by their robust, strongly ribbed shells and by their role as biostratigraphic markers of the Albian. The genus Hoplites has long been of interest to paleontologists due to its restricted stratigraphic range and distinctive morphology, which make it ideal for dating Lower Cretaceous sequences.

Morphological Features

Hoplites ammonites are typically involute, with later whorls covering much of the earlier coils. Their shells display strong, evenly spaced ribs that often bifurcate or branch as they extend outward, sweeping across the flanks and over the venter. In some species, small tubercles occur on the ventrolateral margins, adding to the ornamentation. The venter is generally narrow, with ribs continuing uninterrupted, giving the fossil a bold, sculptured appearance. This combination of features makes Hoplites fossils instantly recognizable and highly attractive to collectors.

Scientific and Collector Importance

Hoplites ammonites play a key role in biostratigraphy, particularly within the Middle Albian. Their clearly defined morphology and restricted occurrence in time make them essential for subdividing the Albian into finer zonal schemes. Beyond their scientific use, specimens from France—especially those from Troyes—are prized by collectors for their provenance, preservation, and historical importance. Ammonites from this region have been studied since the 19th century and continue to contribute to paleontological knowledge today. This specimen represents both a valuable scientific reference and a beautiful natural history piece.

Provenance and Authenticity

This fossil was collected near Troyes, France, an important Cretaceous locality well known for its fossiliferous deposits. Every fossil we offer is carefully chosen for its preservation, authenticity, and provenance. Each specimen comes with a Certificate of Authenticity, guaranteeing that it is a genuine, natural fossil. Secure packaging ensures it will reach you safely.

This rare Hoplites ammonite fossil from the Middle Albian of Troyes, France, is an excellent example of a scientifically important and visually striking specimen. With its sharp ribbing, historical provenance, and genuine authenticity, it is a superb addition to any ammonite, Cretaceous fossil, or natural history collection.
