I always liked the stegosaurus, and diplodocus, although I'm not sure they're even called that anymore.
One thing I'd like to find out though. I was told, many, many years ago, that you couldn't have dinosaurs around now because there's not enough oxygen in the environment to support such large creatures. The same reason we no longer have 2-foot long dragonflies. The really big spiders you see have primitive lungs where as most insects just have trachea holes that extend to every cell in their body. They don't breath, the oxygen just gets in there. Dinosaurs had lungs but you need to have a bit more oxygen for the body to process enough energy to make bones larger.
I can't remember exactly the explanation, but something like that. But if that's true, you wouldn't be able to create clones of dinosaurs in this day and age, at least not the larger ones. Anyone know if this is true?
Here's a link showing Oxygen percentage of the atmosphere that confirms what I remember.
