5.2" Stephanoceras Ammonite - Kirchberg, Switzerland

This is is a nicely prepared 5.2" Ammonite (Stephanoceras) from Kirchberg, Switzerland. This uncommon ammonite is fully inflated with very nice surface detail including the distinctive ridges and nodes. There are two repaired cracks. The outer shell is worn toward the inside of the coil, leaving the suture pattern visible.

The genus Stephanoceras is commonly used as an index fossil to help identify the Bajocian Stage of the Middle Jurassic, approximately 164-170 million years old.

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 ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
