When I was a wee lad I had a book of Dinosaurs, it was quite informative, but also gave an insight into how dinosaurs lived. It had a number of illustrations , one of which was a fight between a Triceratops and a Tyranosauras Rex. In the story of the fight, the T-Rex attacked the Triceratops, and managed to injure it, but was gored and had to retreat to lick his wounds (though presumably very carefully). As an aside it mentioned that this was quite unusual - as the Triceratops usually got eaten for lunch. So I always liked that particular Triceratops as he mean and horny and biffed a Tyranosauras Rex - something it could tell the little ones about, anyway.
