Huge, 18.2" Jurassic Ammonite Fossil - Madagascar

This is a huge, 18.2" wide ammonite fossil from Madagascar. It is Late Jurassic in age and it was collected near Sakaraha, Madagascar.

This specimen includes a metal display 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.
