After all the avian theropod it is time for a good old huge and non-avian one. Here’s the AMNH Hall of Saurischian Dinosaurs Allosaurus fragilis gypsicranium (the plaster-headed subspecies of A. fragilis)
Another view, which shows the plaster in all its glory:
Note the erect limb posture, on a mount from 1908! And please ignore the pronated hands. This specimen needed them to hold its little grandma-style bag 😉
Brian Switek posted a nice description of the story of this mount a while ago, with some info on the poor “Brontosaurus” under it. Go read it 🙂
The other AMNH Allosaurus mount (a complete cast, but of very good quality) featured on dinosaurpalaeo before. I’ll throw in another picture – your task, should you choose to accept it, is to spot the German sauropod researcher in it.
and a last one, this one without any funny Europeans in it.
I like how agile the animal is posed, although the feeding scene from 1908 has its own charm.

As I still have only a rather vague notion of what the German sauropod researcher looks like, it is somewhat harder for me to spot him… 😛
Likewise, but if I had to guess, I’d say that he’s the guy at the back in the grey jacket talking to the lady, visible under the right manus.
Yep, that’s Martin Sander. 🙂
