Ammonite with Stichtite Inlay, 21.5cm

This Ammonite has carved pieces of Stichtite expertly inlayed into its empty chambers, creating a new piece of art. Ammonites were Cephalopods sharing a common ancestor with the squid and octopus. The ammonites that appeared in the Devonian became very diverse and widespread in the Paleozoic and Mesozoic before going extinct along with the dinosaurs at the end of the Cretaceous period. The goniatites lived early in the Devonian period, some 400 million years ago, and became extinct during the Permian period. Stand and gift box included
