Who wants to help me identify some bones! I didn't have anything to measure so I placed them on a railway track, hope that helps!
My immediate thought was a medium sized carnivore, about the size of a fox or badger. However there are features of this collection of bones which could exclude both suggestions. Were these found in the UK?
In photo 1385, top row left to right, humerus, lower end of tibia, upper end of tibia, two fragments of fibula, bit of pelvis and then vertebra. Bottom row, ribs. I note that there are a number of long tail vertebra indicating that this animal had a long tail. The tranverse processes of the lumbar vertebra do not look typical for a fox, they look more badger like. The humerus is long and thin, like a fox, unlike a badger.
There are fox skeleton photos here:-
and badger further down the page.
I think these bones are too big to be from mink. Railway sleepers are usually 250mm or 300mm across, assuming yours are the smaller dimension the humerus is about 120mm long. Mink humerus are only 40mm long.
There is a link which includes a list of carnivore humerus lengths here
