Flashy Red Iridescent Ammonite - 2.85" Wide

Photos don't do justice to this 110 million year old, polished ammonite fossil. It shines with brilliant iridescent red hues when the light hits it from certain angles.

Ammonites

are an extinct group of marine invertebrate animals which died out at the end of the Cretaceous period. These mollusks are more closely related to living coleoids (i.e. octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species.
