2.7" Red Flash Ammonite Fossil - Madagascar

Photos don't do justice to this 110 million year old, polished ammonite fossil. It shines with brilliant iridescent red hues when the light hits it from certain angles.

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.
