[Note Guidelines] Photographer's Note
Amonits are a group of marine animals (subclass Ammonoidea) in the phylum Mollusca and class Cephalopoda. Their closest living relative is probably not the modern Nautilus, which they resemble, but rather the Subclass Coleoidea (octopus, squid, and cuttlefish). Their fossil shells take the form of flat spirals (though there are some rarer helically spiraled and non-spiraled forms, called heteromorphs) and are responsible for the animals' name as they somewhat resemble a tightly coiled ram's horn (the Egyptian god Ammon (Amun) was commonly depicted as a man with ram's horns). Plinius the Elder (died 79 AD near Pompeii) called fossils of these animals ammonis cornua, "horn of Ammon". Often the name of ammonite species ends in ceras, Greek (κέρας) for "horn" (e.g. Pleuroceras).

Hello Marjan,
Interesting picture. The ammonite looks like one fron Patagonia. The rocks where its found is selling to decorate walls.
Very useful note.

Hi Marjan!
Very interesting shot! I saw many of these amonites in my wife's univ. museum and on expositions in Lodz. I own few also. High quality photo, nice composition with perfect black BG. Good work!
