.75" Agatized Ammonite (Lytoceras) Fossil in Rock - Mistelgau, Germany

This is a .75" wide ammonite fossil of the species Lytoceras siemensi that was collected from the Lower Jurassic Age, Lias Epsilon of Mistelgau, Germany. It has been partially exposed from the surrounding rock. Two edges of the rock have been cut flat for presentation purposes.

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.
