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

This is a .93" 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 cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
