Okay, I fibbed. It's not in the tank yet, but I do have some pics. I apologize for the lousy quality, and will say that the cardboard is so you can't see my embarrassingly messy room. I can't really figure out how to do this, so you'll have to copy/paste these codes into your web browser to see the pics.
I just coated the bones in epoxy, so now they're hanging up to dry. Yes, I have epoxy-covered squirrel bones hanging from a string in my room. Yes, this is normal around here.
This is the skull, with a runny nose from the epoxy
As promised, two pics of the cow vertebrae in the tank.
