As was stated, this is indeed an ammonite fossil. Yours is actually quite a nice specimen. I'm sure you are familiar with the countless ammonite fossils that are always for sale in all manner of gift shops, from the Science Store to Disney, to everywhere else. Usually they are sold in their polished form, and will look like this:
In the picture you can see the "uncoiled" long version, and the "coiled" version as well. These fossils, for all their beauty, are usually elaborate scams in essense. Examine the fossil on the bottom right of the picture. Yes, it is in the correct shape....but that's all it is, a shape. There is a small amount of the actual ammonite present in the very center, but other than that it is just polished rock, in a shape that the average consumer will interpret to be a fossil.
The top right fossil in the picture is actually a good specimen, but again, has been enlarged. You can clearly see where the fossil ends - the white ring-like layered ammonite. The straight flat ammonite in the picture is fairly true to the actual ammonite, and only slightly enlarged.
Your specimen would look something like this if it was not encased in the larger rock:
