 Description:
This fine ammonite is Cleoniceras from Madagascar which has much
of the original iridescent shell present. This is a consequence
of light passing through the various layers of aragonite and conchiolin
deposited by the ammonite in life. The lack of acidity in the depositional
environment allowed them to be preserved as you see it here. Notice
the play of colors when the viewer’s aspect changes. The
background to this one is reddish, a most unusual coloration, and
the only such example I have. |
