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 cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
