You go to the zoo if it's alive.

Yeah, yeah.

What do we know about... Not much.

There's a T-Rex brain, or at least a very rough cast of part of one.

That's the actual look of... Yeah, this is...

So dinosaurs, in fact, most reptiles, I wonder if you can see it on the Velociraptor.

Not really, unfortunately.

It's elongated.

Yeah, but it's more that they have, we are weird in that we have a brain that basically fills the inside of our skull.

What most animals have is actually a little kind of sub skull inside the main skull, which is called the endocast.

or endocrinium, and the brain is in that.

And even then, it's not like full of brain, because we've packed an awful lot of brain into our limited space, and they then have quite a lot of goo and fat and other stuff around it.

But it means for dinosaurs, and then reptiles and birds in general, in the old days, you could basically cut one open, but now we'll CT scan through them.

You can take an internal mold of the endocranium, the brain case, and then whatever filled that would have been the brain and its surrounding tissues.

And that's how you get something like this.

In this case, someone literally cracked open an old skull and basically took an internal mold in the same way that you do an external mold for the skulls.

And that tells you quite a lot about certain things.

So, for example, you've got a bulb at the front, which is the olfactory bulb.

So brains are very stereotyped.

Again, ours are super weird.
