7.2" Cretaceous Fossil Ammonite (Placenticeras) - Texas

This is a 7.2" wide ammonite (Placenticeras cumminsi) from the Britton Formation of Dallas, Texas. Comes with an acrylic display 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. Ammonites appeared in the fossil record about 240 million years. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
