This
A complete fossil of Hybodus from Germany showing placement of spine. Image under GNU Free Documentation License
is a nice dorsal spine of the extinct Cretaceous aged shark Hybodus. These large spines helped to support the dorsal fins of the shark.
It's pretty rare to find the spines as complete as this one, and most of them on the market are composites of multiple partial spines. This on only has a single repaired crack.

Hybodus was a small shark that grew up to 2 meters in length and was likely an opportunistic predator. It had a streamlined shape ideal for hunting down fast prey and two different types of teeth: sharp cutting teeth for catching prey and flatter grinding teeth for crushing. This combination may have been the key to Hybodus' success.
