Dinosaur themes in science fiction

[Joe Gilvary <dinosaur@gilvary.net>]

Hi,

I'm looking into themes that have shown up in dinosaur science fiction, 
like the genetic recovery idea from "Our Lady of the Sauropods" and 
"Jurassic Park," or the "dinosaurs survived in a remote places" theme 
that's shown up over and over again as in "Lost World," "The Valley of 
Gwangi," "Baby," "Dinosaur Summer". What are some of the most impressive 
ideas in fiction regarding dinosaurs?

 Thanks,

 Joe
