Colorful Iridescent Cleoniceras sp. Ammonite from Madagascar
The Sp. Cleoniceras
110 million years ago. Tulear, Madagascar
This ammonite has Iridescent coloring (mother of pearl). It measures at 2 3/4 x 2 1/8 x 1/8. The picture doesn't do this ammonite justice. It is very colorful every rainbow color. It is very pretty when you adjust it at all angles. It is too hard to tell from the picture.
Ammonites flourished in the ancient oceans, near the continents, at
all water depths. They were carnivorous, probably very agile and
intelligent, like their modern relative the Nautilus. They are an
extinct group of marine animals. These cephalopods range in size from
less than an inch to 9 feet in diameter.
