2.5" Fossil Ammonite (Dactylioceras) On Shale- Germany

This is a 2.5" ammonite (Dactylioceras) from the Posidonia Shale near Holzmaden, Germany. It is nicely prepared on the shale in which it was fossilized. The detail of this specimen is excellent and makes a striking display.

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.
