5 Inch Ammonite - Polished One Side - Iridescent Other

This is a very cool ammonite fossil from the Middle Cretaceous of Madagascar. One side has been highly polished while the reverse side is covered with a silver Iridescent shell. Take a look at the photos to see the contrast. This specimen would make a great display on the included stand.

Ammonites were predatory mollusks that resembled squids with shells. These cephalopods had eyes, tentacles, and spiral shells. Though their shells resemble that of a nautilus, they are actually more closely related to living octopuses. Ammonites appeared in the fossil record about 240 million years ago, barely surviving several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
