Pennsylvanian period calamite

Found this last night underground last night at work. Hard to find large ones.

What is it?

Very nice, I've gone through a lot of river coal, and yeah I've never seen one that big before. Three segments even! And to rock, its a section of a calamite, imagine a horsetail reed that grows today near lakes but with the posibility of growing huge. Coal can be pretty fantastic under a microscope too...

OK thanks, I am not very good when it comes to fossils but I do like them.
