Are simetric holes on one side, in the other are not so simetric.

I would hazard a guess that it is a trace fossil or some form of fossil bark or fern.

Perhaps try a forum that deals with fossils for help..

After looking more closely there is some carboniferous material present in the pockets (the black coal like deposit}
