4.45" Jurassic Ammonite (Stephanoceras) - Kirchberg, Switzerland

This is a beautiful, 4.45" wide, Middle Jurassic ammonite (Stephanoceras sp) fossil collected near Kirchberg, Switzerland. You don't see that many of these ammonites available on the market and this is a detailed and nicely prepared specimen. There are several other fossils including a smaller ammonite, gastropod and two bivalves present in the matrix on one side of the piece. It stands up nicely on a hard surface without the need for a 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. 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.
