7.8" Ammonite (Speetoniceras) Fossil in Decorative Simbircite Display
This is a beautiful, 7.8" wide Speetoniceras versicolor ammonite fossil from the Lower Cretaceous deposits of the Volga River in Russia. It has been beautifully prepared and inlaid into a base of fluorescent simbircite (calcite and argillite rock). The edges of the simbircite have been polished to a glossy finish, with a textured interior that surrounds the ammonite. This makes for an absolutely gorgeous decorative piece that could be displayed either laying down on a flat surface, hanging, or on the accompanied display stand.
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.
