Three (fossilized?) fragments of bones

I thought tibias had a triangular proximal cross-section.  I don't see any image in this thread that suggests to me a tibia.

This is the distal end.  Yes, a mammal tibia is very triangular in cross section on the proximal end.

This is the best I can get:  @Sharkbyte found a pair in the Peace River in 2011, looks like the Epiphysis is missing.  Match to my find, but not likely a match for a proximal phalanx found in Poland....    but possibly there were Camelids in Poland ???? 

I've checked and there weren't any. Thank you.

Anything is possible, I suppose.  All the familiar distal tibias I looked at are sculptured with grooves and ridges.  The articulation end, even minus the epiphysis, might reflect the contours of the astragalus . . . not in this case.  This could be something less common, but I don't know what it (3rd image) is.
