2.7" Cretaceous Ammonite (Craspedodiscus) Fossil

Cretaceous Ammonite (Craspedodiscus) Fossil #228154

This is a very displayable specimen of Craspedodiscus discofalcatus from the Volga River region of Russia. It has been nicely prepared from the large block of solid limestone and displays aesthetically on a flat surface. The limestone around the ammonite has been textured and the remaining limestone has been polished to a glossy finish.

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.
