3.5" Shloenbacchia Ammonite With Crystal Chambers
This is a beautiful, polished ammonite specimen collected near Khenifra, Morocco. It's of the genus Shloenbacchia and the inner chambers filled with crystals are exposed and visible. These are the first ammonites of this type I've had available. It 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.
