For anyone interested in a more in-depth study of dinosaurs, consider this
hallmark paper of Chick, 2007, which scientifically approaches this issue. Note the anatomy of the snake when it gives the apple to Adam and Eve: it is very much like a dinosaur. It is highly probable that dinosaurs were described as "snakes" in the Bible, according to Chick. Maybe that is also why dinosaurs all went extinct within a few decades after the Floodwaters subsided, besides being unable to breathe the new, oxygen-poor air: they were punished by God for causing the Fall of Man.
