I remember having one of those massive books of dinosaurs when I was a little kid - learned enough species from that to make picking out a single favorite tough. But off the top of my head...I always liked Baryonyx. Part of that's just that the name is very cool, but those sick claws don't hurt, either.
Also rad: the classic T-Rex, Utahraptor, Deinonychus...hard to go wrong with a big, carnivorous theropod. As far as sauropods go, Ankylosaurus is the top of the heap for me. Mosasaurus wasn't technically a dinosaur, but a notable appearance in one of those ancient-nature documentaries left a big impression on me, and as a giant reptile from the Cretaceous, it's close enough in spirit to at least rate a mention.
