12.1" Fossil Baculites With Iridescent Shell - Reduced Price

This is a 12.1 inch long Baculites fossil from the Pierre Shale of South Dakota. Baculites ("walking stick rock") is an extinct cephalopod genus with a nearly straight shell. The matrix it is preserved in has been sculpted so that it stands up freely, making for a very aesthetic display. It's approximately 75 million years old, and comes from a time when a shallow sea covered much of South Dakota.

It has been prepared from the hard concretion in which it was found. Much of the shell has brilliant green iridescent hues when the light hits it from the right angle.
