Found at Wilkeson WA.

Looking for some ID on these if anyone knows. 

Just trying to understand what I might have here. These were found around the coke ovens in Wilkeson. 

#1 Flat wood looking striations. 

#2 Black speckled

#3 Small dark pours evident

Originally I was thinking septarian nodule based on #3 and #2 until I realized they were separate pieces.

The first two items look like slag, to me. 

The last looks like concrete. 

The third item may be plant material,  or ichnofossils.

Slag could be an answer... The coke o ens do have some of what looks like remnants from the coking process.

Coal shale possibly including poorly preserved plant fossils. Bracketed by slag, first and last photos.

The last may be the refractory cement that lined the oven.

Thanks for this Rockwood. After some more research is it possible that the smaller one is Tenorite? Thanks everyone for your eyes on these. I'm a newb so learning as I go :-)

Make sure I get supervision on this before you consider it definite.

If you put a small bit of it over a flame it should be easy to tell if the black is carbon. The worst that seems likely if it is Tenorite is you smelt some copper, but that is unlikely.
