Roget's Thesaurus

I remember finding a book called "Roget's Thesaurus" when I was little and being disappointed that very little of it was about dinosaurs.

It should have been an exciting story about a boy called Roget (who should have been Roger but they hit the wrong key) and his pet dinosaur.

Instead it was just lists of words most of which had nothing to do with dinosaurs. It didn't even explain why it had such a dinosaury title.

So in the unlikely event that I ever discover a new species of dinosaur and so get privilege of naming it, I shall name it Thesaurus rogeti.
