This listing offers a genuine Hildoceras semipolitum ammonite fossil from the Lower Toarcian stage of the Jurassic period, sourced from Lozère, France. This carefully selected specimen represents an iconic ammonite genus and displays the distinct features that make it highly desirable among collectors and enthusiasts. The fossil comes with a Certificate of Authenticity, guaranteeing it as a 100% genuine natural specimen. The photo provided shows the exact fossil you will receive, making this a truly one-of-a-kind addition to any collection.

Geological Age and Formation

The fossil dates to the Lower Toarcian stage of the Early Jurassic, approximately 182 to 174 million years ago. During this time, the area that is now southern France was covered by warm, shallow seas that supported abundant marine life. Sediment deposited in these environments created rich fossil-bearing layers, preserving ammonites and other marine organisms in remarkable detail. Lozère is particularly well known for yielding fine ammonite specimens that exhibit excellent preservation.

Fossil Species and Morphology

The Hildoceras semipolitum belongs to the family Hildoceratidae, within the superfamily Hildoceratoidea, and order Ammonitida. This species is notable for its elegantly coiled shell, compressed whorls, and strong ribbing. The rib patterns radiate across the shell and often bifurcate as they approach the outer margin, creating a striking visual display. These features not only add to the aesthetic appeal of the fossil but also provide key identification markers used by paleontologists.

This ammonite’s morphology reflects its adaptation as a free-swimming cephalopod. Like modern squid and octopuses, ammonites were active marine predators. The chambered shell functioned as a buoyancy device, allowing the animal to control its position in the water column while pursuing prey.

Scientific and Collecting Significance

Hildoceras ammonites are valuable to paleontologists because they are excellent index fossils, meaning they help define and correlate the relative ages of rock layers across different regions. Their rapid evolutionary changes and wide geographic distribution make them important markers in Jurassic stratigraphy. For collectors, this specimen represents not only an attractive display piece but also a scientifically meaningful fossil tied to the broader understanding of Earth’s history.

Origin and Authenticity

This specimen originates from Lozère, France, a locality renowned for its high-quality ammonite fossils. Each fossil is carefully chosen for its clarity, preservation, and scientific value. As with all of our specimens, this ammonite comes with a Certificate of Authenticity, assuring you that it is a genuine fossil and not a replica or reproduction.

Perfect for Display and Education

Whether you are a fossil collector, a student of paleontology, or someone who simply appreciates natural history, this ammonite fossil makes an excellent addition to any collection. It is ideal for display in a home, study, or educational setting, where its intricate detail can be admired up close. The scale rule in the photo (1cm cube) provides accurate sizing, so you can assess its true dimensions before purchase.

This Hildoceras semipolitum ammonite fossil is a unique piece of natural history, combining scientific importance with striking natural beauty, and it is available now as the exact specimen shown in the photographs.
