Large 4 1/2 Inch Douvilleiceras Ammonite - Bumpy

Here is a nice ammonite of a genus not typically seen from Madagascar, Douvilleiceras. It's the largest specimen of this type I've had yet at 4 1/2 inches wide, very thick and weighing nearly 2 pounds. It's been polished and shows off it's very distinctive bumps and ridges well.
