1784987545Code 8565 Fossil AmmoniteFossil ammonite from the desert of Madagascar, in good condition, its chambers filled with warm amber-colored calcite crystals during the fossilization process.
Mounted on a custom-made iron and brass base.
The period is referable to the Jurassic (150–170 million years ago).
Good condition. Ammonite dimensions: 18.5 x 3 x 15.5 cm – 7.3 x 1.2 x 6.2 in.
Ammonites belong to a group of extinct marine animals that lived over a very long period from the Paleozoic Era to the end of the Mesozoic Era, between 400 and 65 million years ago, when they disappeared along with many other organisms (dinosaurs, flying and aquatic reptiles) during the well-known biological crisis of the end of the Cretaceous.
They possessed a chambered shell, that is, divided into chambers, generally coiled in a spiral.
Ammonites were skilled swimmers thanks to the particular structure of their shells. After the first chamber, called the living chamber, in which the animal lived, there followed a series of watertight chambers with a siphon running through them. These chambers could be easily filled with gas, allowing them to float perfectly, sinking or rising to the surface, just like modern submarines. They also used a jet propulsion system for horizontal movement. Numerous forms of ammonites have existed over time, allowing scientists to use them to date the rocks in which they are found, which is why they are called "guide fossils."
Being exclusively marine organisms, their discovery also provides information on the presence of ancient seas at the excavation site.
Due to their great scientific importance and the beauty of their forms, they have always been considered the symbol of paleontology.
