Ryan quotes from Primeval

Ryan

[Stephen touches the Pteranodon dung and licks it as the other soldiers cringe] That's just not right.

Capt. Ryan

They were like spiders, but with pincers, not fangs. Some of them over a meter long. Horrible little...

Nick

Look, how do you feel?

Capt. Ryan

Sick. My ears are ringing...

Nick

Any blurred vision?

Capt. Ryan

No. But there's something else. The gunshots were too bright, like fireworks.

Stephen

That's classic signs of excess oxygen in the atmosphere.

Nick

Richer, more heavily oxygenated air must be seeping through from another anomaly. But we're not talking about the Permian era any longer. This is much, much earlier.

Claudia

How much earlier?

Nick

Maybe the Carboniferous, about three hundred million years ago.

Capt. Ryan

[On dead dodo] Professor, we have a dodo down.

Claudia

Oh, no.

Abby

How did that happen?

Connor

Maybe he ate one of the pies.

Nick

It was one step ahead of us all the time. It knew what we were going to do before we did it!

Helen

I warned you it was smart!

Nick

It would be more useful if you could tell us how to catch this thing.

Stephen

What we need is some kind of edge, a weakness in its defences that gives us an advantage, otherwise it's just gonna pick us off one-by-one!

Connor

Dogs. The dogs went crazy before it attacked. What would make them go off like that?

Stephen

Can't be smell. If there was a scent trail, they would have followed it.

Nick

Hearing. They heard something.

Connor

Sound. It's using sound.

Nick

That's why it was able to remain one step ahead of us! It can detect physical movement before it's within visual range!

Connor

And the dogs, they detect a higher frequency, therefore they know when it's nearby!

Ryan

Like echolocation?

Nick

High frequency sound waves, it's like a sonar system. Some animals use it to detect prey.

Stephen

Like a bat. Well, you said there was bat blood in the lion enclosure.

Connor

That's it. This thing must be some kind of...I dunno, super-bat.

Helen

He's right. Three quarters of all mammal species are bats or rats; maybe the future belongs to them.
