There's one with a lizard inside it.

And there's one with a fish inside it.

on their own, and this happened for at least two of the papers describing these things, it's like, it ate fish.

These are fish-eating animals.

No, that one ate one fish once.

That one ate one bird once.

That one ate one mammal once, and that one ate one lizard once.

So what have we actually got here?

I suspect we've got a group of generalists and we just happen to have found them eating different things at different times.

But equally, it's also possible, at least, that, yeah, this is one of these things and it had learned to eat fish when the others hadn't.

And actually, this was most of the fish eaters and the others ate whatever they could get.

Maybe one caught a bird up a tree in a nest.

Maybe one found it dead on the ground.

You don't really know what one of these things on its own is fascinating, but potentially misleading.

Yeah, and that's... So one thing I've definitely written about is, yeah, the independent lines of evidence.

Can you get stuff that is as far as possible truly independent from the other data, and does it give you the same answer?

And then when it does...

That's incredibly powerful.

So Spinosaurus or the Spinosaurus as a whole is my go-to example for this.

So the guys, the famous big sailback and the weird crocodile-like head, though some of them look rather different to that.
