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 cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
