And things like crows and parrots sit very neatly on a couple of different curves.

There's a curve for reptiles, a curve for birds, a curve for mammals, and things like this.

And basically, that's it.

But also, actually, our understanding with mass estimates for dinosaurs is good but not great.

And so you could easily be out by...

you could easily be out by like 20 or 30% on the volume of the brain inside the brain case.

And then you could be out by 20 or 30% on your mass estimate.

Well, now suddenly it's very easy to make the brain too big and the animal too light.

And it's super smart or make the brain too small and the animal too heavy.

And it's super dumb.

That's awkward, unfortunately.

Yeah, and then that was shot down within a few months by a team of paleontologists and a couple of other neurologists who really went to town on it.

Just counting the number of... Trying to estimate the number of neurons.

Yeah, it was the neuron density thing.

And yeah, I...

I unsurprisingly support the revised one, which was done by a whole bunch.

Yeah, the Caspar paper.

I've spoken to Caspar about it, a couple of the other authors.

Yeah, which is kind of what you'd expect.

I mean, a couple of other people at various times have suggested they're really smart.
