This appears to be a septarian nodule, a clay ball that has dried and cracked. The cracks then were infiltrated by minerals, often the mineral is calcite in crystals.

It's not a rock, it's a 'septarian nodule' as stated above. Do a Google image search for 'septarian nodule' and you'll see many just like yours.

Looks like a septarian here is a really old one I found. Looks just like one. But thats a much newer and nicer one. Good luck. You can see the cracking on the lower right. (this is a much older specimen it actually cracke in half in my hands. But you can see cracking on it. Good luck.
