2.0" Fossil Ammonite (Arctoceras) - Nevada
This is a 2.0" fossil ammonite (Arctoceras) from the Thaynes Formation near Elko City, Nevada. It is in good condition with a repaired crack and some of the rock in which it was fossilized remaining near the opening.
This ammonite comes out of an old fossil collection we recently purchased with a lot of unique material from unusual and often no longer accessible sites.

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.
