1.7" Permian Ammonite (Uraloceras) Fossil - Russia

This is a 1.7" wide fossil ammonite (Uraloceras complanatum) that was collected from the Lower Permian deposits in the Ural Mountains of Russia. It has been exposed from the rock it was found in, revealing the incredible pattern of the inner shell sutures. A small section of rock has been left on the back side of this ammonite.

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.
