What fossil is this?

I found this while fishing on the beach if a cove in Massachusetts. It was below a huge rock cliff. Other fossils have been found in the same cove. I don't know what kind of rock the cliff is but this was certainly way different.

Iron carbonate concretion.

Very interesting specimen. Not a fossil, but definitely worth collecting.

Since this is a concretion should I attempt to break it open?

You can if you like. Concretions are quite common. I usually hang on to a specimen until I'm quite sure that I can easily find another like it or until I actually do. This way you don't demolish something you can't replace. If you decide that you must know what's inside, go for it. Like I said, concretions of this type are quite common, and in general any rock you find in any area is only one of many like it. It can be one-of-a-kind, but the odds of that are slim. You know the area where you found it much better than I do. It's your choice.

There probably won't be fossils in it.

I agree, but it's fun and educational to see what's inside sometimes, especially for those who are new to fossils and geology in general.

 Agreed. Had things progressed differently the carbonate may have become shell fossils. The degree of homogenization makes it seem unlikely to contain a fossil though.
