At the end of the episode we learn it was the pterosaurs that killed the golfer. When they attack the house, they’re making a hell of a racket, yet they seem to come down on the golfer in complete silence. Also, would they all co-operate to such an extent that a load of them would lift him off the ground together?

Great moment: Rex doing his nodding dog impression in the back of the car.

London is not completely empty on a Saturday. It’s amazing that no-one else saw the pterodon flying around.

How do Nick, Stephen and Claudia get into the office block if it’s empty?

Claudia takes forever to announce that she’s blind, not even telling the medic while he’s talking to her.

Pterosaur is the generic name for the winged reptiles. Apparently the small pterosaurs were a fictional version of Anurognathus.

That golfer wasn't too bright, dropping his only source of defense when running away.

When the pteranodon was closing in on Conner I thought, "Throw your hat in the air!" You'd think that might distract the beastie.

I wonder what happened to those tranquilizers that missed when the pteranodon was flying. Hope nobody was below. ("Why look! Is that a pterano... Aaaaaa...!" *thud*)

That must have been a powerful tranquilizer to knock the pteranodon out so quickly.

This episode would make a good double bill with Hitchcock's The Birds. I wonder how many scenes were direct ripo... errr... 'homages'. ;-)

Those anurognathuses sure roasted quickly.

You really need to watch the Scottish Falsetto Sock Puppet Theatre's take on the show, Primarkeval, Keith. If you can work your way through the thick accents, they say everything sarcastic that you say about the show!

The accents not so bad it's the high-pitched fast-talking that makes it tough, but yeah, Primarkeval was cute.
