5.4 Inch Polished Ammonite - Red Iredescents

Here is a gorgeous polished Cleoniceras ammonite fossil from the Cretaceous deposits of Madagascar. It's 5.4 inches in diameter and has some great fiery red iredescent hues when you catch it in the right light.

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.
