Thick, 13.5" Polished Ammonite - Jurassic

This is a classic Late Jurassic ammonite fossil from Madagascar. It's 13.5" wide and preserves the distinctive ridges of this type of ammonite.

It makes an impressive display on the included metal stand.

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.
