Because again, if you've got a long nose and you're pulling with quite a lot of force at the very tip, that's going to bend your snout.

What's the story of the evolution?

So Tyrannosaurs go back to the middle Jurassic.

So Tyrannosaurs ran for 100 million years.

So from about 160-ish, 165-ish million years till the extinction started.

66.5, I think, is the current dating on that.

So yeah, you've got 100 million years of them.

And the Middle Jurassic, annoyingly, is probably the bit of the Mesozoic, so the whole dinosaur period, that we know the least of.

Just by chance, we just don't have many rocks exposed of the right age that...

fossil bearing.

But we got two or three Tyrannosaurs from that time.

And yeah, they're really quite diddy.

Yeah, they'd be chest high to us.

Two or three meters long, including the tail.

Probably more like three, a lot of them.

Little heads.

Long arms.

They look like every other carnivore going.

There's not a lot special to them at this point.

They've only just separated from their nearest groups, which is actually something like the ancestors of Giganotosaurus, actually.
