18.3" Iridescent Ammonite (Deshayesites & Aconeceras) Cluster

This is a phenomenal cluster of Deshayesites deshayesi and Aconeceras trautscholdi ammonites from the Lower Cretaceous (Aptian) deposits of Saratov, Russia. They have been beautifully prepared from the hard concretion from which they were found. The ammonites have a wonderful iridescent shell preservation and the largest complete ammonite (Deshayesites) is 2.35" wide. The back of the rock has been cut flat.

It comes with a display stand to assist with presentation. The rock was collected in five separate pieces, requiring crack repair and some spots of gap fill within the rock.

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.
