I've actually seen Sophie now. There are aspects of the Natural History Museum that need an update. Much of the Dinosaur gallery is suspended for viewing from an elevated walkway that can no longer be accessed, so it's a little difficult to see some of the animals there now. There's also quite a bit of outdated info there. Still, the mount for Sophie is very well done, and she was one of the first things we saw as we entered from the second door.

This is definitely the same way I feel after having watched prehistoric planet, like I knew a lot of popular depictions had issues before that, but now seeing depictions of theropods with their teeth sticking out and looking like they've been plucked and starved is extra jarring. I think a lot of the more accurate depictions now just make things Click, and it's hard to even begrudgingly accept anything less. I guess it reminds me a lot of living predators have that kinda harmless :] face when idle, but then when they open their mouth you get the reminder they ARE predators.

Another thing about the 'two brains' hypothesis. Marsh (and others of the 1880s) would have thought in terms of body parts being "brain" and "not brain". Now we know that not only do some animals have decentralised nervous systems, but loads of animals (even humans) have some of their 'biological decision making' happen in the spinal cord.
