Err, gosh. Do I have to pick a favourite? I love them all!

Favourite to see killing things on TV: Deinonychus
Most aesthetically pleasing (or in this case odd looking): Stegosaurus
Dinosaur I'd most like to take on a date (though not if I'm picking up the restaurant bill): Diplodocus

Oh, and I had a book where a T-Rex attacked a Triceratops and retired wounded, too. Perhaps we all had the same book?
