Gorgeous Androgynoceras Ammonite Cluster (13) - Germany


This is an aesthetic cluster featuring a total of 13 ammonites in a natural association, along with several partial belemnites and impressions of more ammonites. The majority of the ammonites are of the Androgynoceras genus. There is one nicely-repaired crack running through the rock, but no other repairs or restoration that we can see. It makes a beautiful presentation on the included 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. 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.
