26" Wide Polished Ammonite & Nautilus Cluster - Madagascar

 
 
 
 
 
 
Here is a large polished ammonite cluster still embedded in the rock in which they were found. It is 26" x 11" x 8". There are three main ammonites the largest measuring 9.6" wide. On the end ammonites, the polishing has exposed the intricate suture pattern of the inner shell. Many other fossils including clams, gastropods and a nautilus can also be seen in the rock.

The ammonites are Cretaceous (Albian Stage) in age or approximately 110 million years old and are quarried in the Mahajanga Province of Madagascar.



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.
