14" Tall Triassic Ammonite (Ceratites) Cluster - Germany
This is an aesthetic, 14" tall cluster of large, Triassic ammonites (Ceratites sublaevigatus) from Bavaria. The largest of the three ammonites is 7.5" wide and there are also several fossil shellfish associated.
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.
