• Jo Grant : Those things that attacked us. You said you'd seen something like it before.

  Doctor Who : Something very similar, certainly. They emerged from some caves in Derbyshire.

  Jo Grant : The Silurians, wasn't it? The Brigadier was telling me.

  Doctor Who : That's a complete misnomer. The chap who discovered them must have got the period wrong. No, properly speaking, they should have been called the Eocenes.
