Bargain, 3.2" Polished Jurassic Ammonite (Perisphinctes) - Madagascar

This is a 3.2" wide ammonite (Perisphinctes sp.) fossil that was collected near Sakaraha in the Tulear Province of Madagascar. It is Jurassic (Oxfordian Stage) in age or approximately 160 million years old. It has well defined ribbing and is quite heavy. The exterior has been lightly polished and it comes with a display stand.

This ammonite has a section missing towards what could be considered the top, hence the reduced price.

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.
