Bone fossil from the Cretaceous?

[PMA]

Hello,

I found this piece on the tracks in the Nature park Haard near Flaesheim in Germany. Usually this area is Upper Cretacous(Santonian, Campanian) and Weichselian ice age. The rocks seems to be fine sandstone but a little bit different from the quartzite which is usally found in this area. It rather looks like a piece of one, maybe a rib?

They could be bone or wood. I cannot see anything in their cross sections that tells me that they are bone or wood. Can you see anything in their cross sections to help ID them: wood growth rings or spongy bone?

They look like they are hollow in cross section. This perhaps indicates a dinosaurian origin? @Troodon what say you?

No clue, not much of a fragment to determine much,  and not typical of a hollow theropod bone.

Might have to be labeled Chunkosaurus indet.

Mh, I'll try to clean it a little bit more, maybe its a little clearer then.

I cleaned it a little more and took photos, can't really see much in the cross section... @DPS Ammonite @Troodon

Sorry, no change from prior comment

Looks plant-like, to me, given the presence of carbon film.
