Lepidodendron bark piece found in Gelsenkirchen, Germany?

Again I'm not sure what kind of bark this is? Found on old mine pit in Gelsenkirchen.

 

Thanks!

Sort of, but from the other end of the plant. This is known as a stigmaria. A root structure.

@Rockwood thanks! Inside of it were also these little pieces, anything special?

Actually enclosed by the fossil, or just in the same piece of rock ?

Often only a shallow temporal horizon is preserved so something beneath or above it may not be part of it.

It was right underneath the piece of rock in the first picture as you can still see one piece in it down there near my finger.

Better focused pictures without shadows but in good light would help. The pictures you posted are blurry -- keep the camera steady against a large solid object or use a tripod. Get as close as you can but back out if you start losing focus. Crop away the excess from around the specimen in each photo, but drop crop away any of the specimen. Take pictures of all sides of each specimen from the top, all 4 sides, and bottom. Shoot dead-on, not at oblique angles.

 

EDIT: I agree with Stigmaria.

They are likely to be plant fossils,  maybe even part of the internal structure of the stigmaria, but it's hard to be certain from the available information.

Thank you @Mark Kmiecik and @Rockwood, I hope these pictures are better, also one from the bottom side (first pic) of the rock with some imprints

The pieces that came from "the inside" appear to be ironstone-like nodules or concretions. You see these more often in Carboniferous rocks, especially in layers dominated by rooting structures (probably reflecting some specific geochemical conditions).
