Hi all,
I found this piece of mudstone at Besom Hill in Oldham, near Manchester. The rocks here are Upper Carboniferous in age.
One side has unusual lineations, but not the type caused by bedding as seen in the shales that are very common in the area. The reverse side is typical of the mudstones found here. I'm thinking it's a fragment of Walchia trunk, though there isn't any mention of Walchia in any literature or by any other collectors.
Does anyone have any suggestions?
Cheers
