I'm glad you have links to this topic in your sig, mngwa! I never would've thought to look for such a place of similar interest here.
I have a nice start to my collection. Been absent mindedly collecting bones and things since I was little, got serious about it though about... 5 or so years ago? I live on the edge of the forest so I find lots of things. I'll make a full list but as far as biggest I think a cow skull right now is my biggest. She's off getting cleaned thanks to connections (my old high school has a taxidermy class so I sent some specimens that need cleaned to a friend to take care of them for me).
Rest of my collection includes, that I have yet to get pictures of:
- dried sea horse
- dried salamander
- cattle jaw bones (unsure if they're cow or horse)
- bat jaw bones (gotten from owl pellets)
- random deer bones
- the rest of what I could find of Badger's body, which is mostly spine and rib cage
- whole mouse skeleton
- two mouse mummies
- moose antlers
- whole connected bird skeleton, looks mummified
- probably forgetting more for this list too... [/rambling]
