Actually some good creation scientists do believe that dinosaurs did actually go on to the ark. One on the best is Kent Hovind (the man is a genius!! He would easily win a debate with Stephen Dawkins).
Hovind says that Noah could fit the dinosaurs on the ark because he just used teenage ones.
I recommend everyone should watch his videos, they are a real education. If these were shown in public schools we would soon hear nothing of this evolution nonsense.

Genesis 22:2 And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of.
I know God wouldn't let me believe in Him if He didn't exist.
