Beautiful Crystal Lined Ammonite (Half)

Here is a great half of a Cleoniceras ammonite from Madgascar which has been polished to reveal all of the inner detail. Found in Madagascar, it lived in the shallow seas during the Middle Cretaceous Period, approximately 110 million years ago. This specimen is simply beautiful with both agatized and calcite crystal lined cavities. It 4 inches wide and displays wonderfully on the included stand.

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.
