The "man foot" prints are frauds. Even most creationist websites advise not to rely on them.
Do not believe the Roman Coins with dragon depictions on them.
Dragons are right up there with unicorns and centaurs. Right! That's scientific evidence for sure! Take that to the Nobel Prize Committee!
Do not believe the Inca Stones with depictions of dragons on them. Or the fact that the skin pattern depicted was only recently verified.
I thought Inca stones were made for the tourist market?
As to you belief that they went extinct before the flood is unknown. That is assuming you even believe in the Flood of Noah's day.
The flood is a matter of religious belief. There is no scientific evidence supporting a global flood at about 4350 years ago. Early geologists, seeking to document a global flood, gave up about 1830.
Before the flood things lived longer and grew larger. After the flood things did not live as long therefore did not grow as large.
No global flood. See above.
It is a scientific fact that reptiles grow until they die. So pre flood larger, post flood smaller.
No global flood. See above.
There are many legends (which is not a scientific fact, same as evolution is not scientific but a hypothesis on unproved ideals) of dinosaurs seem by tribal people in South America and Africa.
Legends are interesting. I like Zeus and those guys, but Coyote and Eagle are my favorites. Let me know if you are interested in some good Coyote stories.
You write "evolution is not scientific but a hypothesis on unproved ideals" -- nice try. "Ideals" have no role in science, and no theory is considered "proved" in science. And you are further incorrect in that the theory of evolution is indeed a theory, not an hypothesis. See the definitions on my FR homepage.
Your problem is that you seem to think that your religious beliefs are scientific facts. That appears not to be the case.
In the words of one of our greatest pessimistic philosophers:
