Looks like some sort of concretions. They can form by precipitation and recrystallization after burial of the sediment. ...at least that's my best guess. How big is it? |

About half the size of a foot ball. Theres some bigger ones around, heavy too, maybe 30-40 kg in size |

I'll vote for a concretion. Looks like iron compounds. If you want to sell one I'll pay $20 plus shipping for one of about 9-10 pounds. |
