Wholesale Ammonites

This lot contains 50 specimens of Pseudosonneratia. Includes label for each ammonite. These very pretty ammonites exhibit iridescence because nearly all of thier original iridescent shell has been preserved. The iridescence is a consequence of light passing through the various layers of aragonite and conchiolin that was deposited by the living ammonite. The lack of acidity in the depositional environment allowed them to be preserved in this splendid form. The colors change with the viewer’s angle. The lot includes flat, foldups and labels.
