the tragicomic aspect is that my first thought was "in a perfect world, it would be on the FMNH website". But of course I thought surely, someone else would have thought of that first, so it must either not be there, or be difficult to find, so if I try to find it there, I'll either end up sad about the decline of the web, or sad about my own inability to find things, so I didn't try that. Now that I'm trying it, keywords like "Brachiosaurus type specimen" work great and find neat images.
