I was just thinking about the whole struggle of UNIT dating so I wanted to reread these fics. Excellent stories, all... and, yeah, silurians wouldn't be odd in that era..
Fun! When the pteranodon got mentioned I wondered to what extent this was a 'Flintstones' mash-up, but I didn't think that it could be down to non-hostile Silurians until the punchline :-)
Hee, very good! :-)
