Toutes les enchères / Ethnographie / Ammonite - Fossilised animal - Aioloceras (Cleoniceras) sp
Beautiful Polished Ammonite Fossil Slice – Natural Spiral Geometry This stunning ammonite fossil slice showcases the timeless beauty of nature’s design. Cut and polished to reveal its intricate internal chambers, the piece displays warm tones of amber, honey, and cream with naturally occurring crystal and mineral textures. The spiral pattern is sharp and eye-catching, making it perfect for home décor, a collector’s cabinet, or as a unique gift for fossil lovers. This is an extinct cephalopod mollusc belonging to the ammonites. It lived in the Upper Jurassic (172-149 million years ago), and its fossil remains are found on all continents. These are marine animals, characterized by an external shell composed mainly of calcium carbonate, in the form of aragonite, and partly of an organic substance of a protein nature (conchiolin). The shell was internally divided by septa into several chambers, of which the mollusc occupied only the last (living chamber). The others, which made up the phragmocone (chambered part of the shell), were used as "air chambers" (similarly to the current Nautilus), filled with gas and chamber liquid to control the buoyancy of the organism. The pressure of the chamber fluids was controlled by a thin, richly vascularized, partly mineralized tubular organic structure (the siphon), which passed through all the septa and allowed the exchange of fluids from the blood and soft tissues of the animal to the chambers through a process of osmosis. ***“Metal display stand included.
