Jurassic fossil ammonite spiral, natural look, mineral decorative piece

AFW - Antique France Worldwide

Description

This specimen is a Jurassic ammonite fossil, presented here on a decorative background evoking an antique casket made of ornate metal. The visible object is an ammonite with a spiral shell, characterized by well-defined radial ribs and a raised texture typical of this fossil family. The surface has a natural patina with light nuances, oscillating between beige, cream, and subtle grey tones, attesting to its state of preservation and fossilization.

The general shape is that of a regular spiral, with a clearly visible center and progressive coiling towards the outside. The details of the internal septa are discernible, with fine and regular striations that highlight the shell's original structure. The overall appearance of the piece emphasizes the authenticity of the fossil, without decorative additions or excessive polishing, thus retaining its natural and raw look.

The photographed side shows the entire spiral, with well-defined reliefs and a slightly rough surface. No major breakage is visible on this side, although the periphery shows some natural irregularities due to erosion and the fossil's age. No stand or base is integrated into the piece in the photo; the ammonite is simply placed, allowing its mineral structure to be appreciated under soft lighting that enhances its volumes.

The ammonite is photographed in front of an antique metal box adorned with relief patterns, which highlights its decorative character and its potential as an object of curiosity or a centerpiece in a cabinet of curiosities or an interior decoration inspired by nature and mineralogy.

The concentric grooves, typical of Jurassic ammonites, are clearly visible, as is a homogeneous coloration without visible inclusions of crystallization or foreign matter on the exposed surface. No markings, inscriptions, or indications of provenance are visible on the photographed side.

Condition

Used item, sold as is. Presence of natural irregularities inherent to fossilization. No major defects visible on the exposed side.

Did you know? Ammonites are fossil marine mollusks that lived from the Devonian to the Cretaceous periods, approximately 400 to 66 million years ago. Their spiral shells served as floats and allowed them to move in the Jurassic seas, the period during which this specimen lived. Ammonites are often used as index fossils to date geological layers.
