So how on earth do you get from an empty skull to a picture of an actual brain?

Yeah, that's been the million dollar question for a long time.

And it was one of those things that like for years, like as paleontologists were looking at things, there was a lot of people who were interested in that.

And actually, way back when we first started finding dinosaurs in places like North America...

That was a question that a lot of people were interested in.

And in fact, the American Museum of Natural History, they found a T-Rex years and years ago, and they were interested in this very same question.

So what they did was they took one of the T-Rex skulls that they found and they cut the brain case in half just so they could actually see what was inside it.

And if an animal doesn't have a good nose, what happens then?
