Welcome to TFF!

What is the size?

Where was it found?

It's definitely plant - but I don't think it is Calamites sp., if thats what you meant by "calamus".

Maybe a few more pictures from a bit farther away would help, as well.

my guess is from the Cleveland shale...

Which does have ironstone

[ShaunPogacnik]

Yes I did mean Calamites geting my school terms mixed up. It is about an inch across and has pyrite nodules in it. It was found in Lake Co. Oh along the beach of Lake Erie where there is glacial till.  I am not for sure where it came from but it does look like cleveland black shale.

The lack of deep vertical groves and the absence of nodes leads me to believe this is not Calamites sp. 

I would lean more towards this being some sort of branch from something like Cordiates sp. or something similar. 

Not sure you can pin it down further than that.  

Maybe one of the plant guys will chime in.

Just to play devil's advocate and say this were Cleveland Shale, this couldn't be a Calamites. Best bet for rocks like those would be a woody Archaeopteris stem or similar plant piece.

Not like any Calamites I have seen. Interesting specimen. Not sure what to make of it. Difficult to say for coalified remains like these...

The morphology is very similar to Callixylon sp.

 

Callixylon newberryi is attached for comparison.

Those Callixylon newberryi specimens do look pretty similar thank you everyone for your inputs. pretty cool finding a plant fossil in north east ohio even if it's from glacial till.

Nice find. Interesting preservation type.

Here are other comparative specimens (Chester A. Arnold, 1931) showing impression of branch.
