Jurassic fossil ammonite, authentic half-shell, unique piece, fossil

AFW - Antique France Worldwide

Description

This piece features a fossilized ammonite half-shell, characterized by its truncated spiral shape and mottled gray-beige surface. The ammonite, visible on the exposed side, reveals a mineralized structure and natural relief resulting from fossilization. The shell's details, though partially eroded, show subtle traces of internal septa typical of this type of fossil. The texture, both matte and slightly granular, testifies to a long mineralization process. The object is photographed in natural light, highlighting its subtle nuances and asperities. The clean cut on one end suggests a cross-section, allowing the fossilized interior to be observed.

The dominant color is a grayish beige, punctuated by lighter or darker areas depending on the shell's thickness and mineral density. No artificial polishing is visible on the surface, confirming the raw and authentic appearance of the piece. The whole is placed in front of a carved wooden box in a baroque style, which emphasizes the decorative and natural aspect of the ammonite.

The irregular contours and the clean break on the lower part are typical of fossils extracted from their rocky matrix without excessive re-cutting. No inscriptions or added marks are visible on the photographed side. The absence of artificial shine or coloration indicates natural preservation, without varnish or tinting.

Condition

Did you know? Ammonites were spiral-shelled marine mollusks that appeared more than 400 million years ago and disappeared at the end of the Cretaceous period. Their name comes from Ammon, an Egyptian god depicted with spiral horns, evoking the shape of their shell. Ammonite fossils are frequently used as stratigraphic markers to date Jurassic and Cretaceous geological layers.
