Iridescent Ammonite Fossils Mounted In Shale - 5.7"x3.5"

This is a spectacular display piece featuring four iridescent ammonite fossils from the Saratov Region of Russia. These ammonites are Middle Jurassic (Upper Callovian Stage) or approximately 161-164 million years old. There are three Quenstedticeras ammonites ranging from 2.1" wide to the smallest being 1.2" wide; and one .8" wide Eboraciceras ammonite. All of which has been aesthetically mounted in a piece of shale along with a few interesting pyrite formation. The ammonite fossils are entirely real and natural, they have just been mounted in the rock.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
