Medicine Hat unknown Bone

[RachmO]

Hello fossil forum,

 

Recently we were out hiking in the Coulee near Medicine Hat, Alberta! As newbie fossil enthusiasts, we were hoping for some expert weigh ins to help identify this fossilized bone we found. We have some very interest kids (and adults!) who were hoping to narrow it done from Chunkasaurus, to hopefully, a general species. 
 

ID or no ID, we do appreciate any direction on this!

You didn’t remove it from Alberta, did you?

[Troodon]

My initial sense on this bone was reptilian versus dinosaurian.   Difficult to say which one  since its really a non-descript end of a bone

 

One candidate is Champsosaurus.  I've included some photos you can compare against.

Focus on the tibia (T) and Fibula (Fb)

Nope, what’s found in Alberta, stays in Alberta!

I agree with troodon… turtle or croc or even champsosaur rather than dino
