This 3D tyrannosaurus rex skull is an extremely accurate miniaturized version of the real thing. A life size T-rex skull is over four feet long, this little guy is only 1" long from the tip of his nose to the back of his skull. He is made of solid sterling silver. The detail on this piece is so refined that you can actually count the spaced teeth that aren't much thicker than an ordinary pin. This amazing little skull is mounted on your choice of chain.
