3.3" Fossil Ammonite (Placenticeras) - Utah

Fossil Ammonite (Placenticeras) - Utah #119424

This is a beautiful 3.3" fossil ammonite (Placenticeras) from the Tropic Shale Formation near Orderville, Utah. The intricate suture pattern of the inner shell stands out nicely in this specimen. It is still attached on one side to the rock in which it was found.

Comes with an acrylic 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.
