I found some scats that looked a lot like those of a pine marten or otter at 600-700m in the Lake District, UK.
The scat was full of white claw-shaped items, possibly bone, and was 10-15cm long and curled.
The terrain was fairly barren with just grasses and near an exposed ridge, 500m higher and 1km in horizontal distance away from mixed woodland.
Unfortunately I didn't take a photograph.
I'm very new to trailing and tracking, having only picked up a few pointers from friends so sorry for any missed details.
