Jurassic ammonite fossil, curved shape, crenellated surface, unique piece

AFW - Antique France Worldwide

Natural ammonite fossil from the Jurassic period, presented here in a partially preserved form, characteristic of specimens discovered in their raw state. The piece shows a pronounced curvature and a crenellated relief typical of this group of extinct marine organisms, with alternating smooth and finely wavy areas on the exposed surface.

The visible surface displays a palette of shades ranging from light beige to pale grey tones, punctuated by faint darker mineral traces, testifying to the burial and progressive fossilization in the rock. The matte and slightly porous appearance of the structure suggests natural preservation without polishing or apparent treatment.

The shell's relief shows regular grooves, remnants of the ammonite's internal septa, clearly visible on the upper part of the fossil. The incomplete cut reveals an irregular edge, emphasizing the authentic and unique character of the piece. No inscriptions or markings are observable on the presented face.

The photograph highlights the fossil on a black stand with white veined patterns, in contrast with a golden fabric in the background, emphasizing the raw texture and mineral aspect of the object. The careful presentation highlights the decorative and scientific nature of the specimen.

This ammonite fossil is an ideal study piece for observing the typical morphological details of the Jurassic, particularly the spiral structure and traces of internal septa. It is an authentic, unreconstructed specimen, whose irregular shape and natural patina are entirely visible in the photo.

Condition: Used item, sold as is. The surface presents a natural patina, with irregularities and roughness inherent to its original fossilization.

Did you know? Ammonites are cephalopod mollusks that appeared more than 400 million years ago and became extinct at the end of the Cretaceous period, about 66 million years ago. Their spiral shell, divided into chambers, is emblematic of Jurassic marine fossils and is now used to precisely date the geological layers where they are found.
