In an American West ruled by dinosaurs, a young Teddy Roosevelt goes on an expedition into the Yellowstone to hunt one of the last of the great predators, confronting his and his nation’s destiny.

I think it is a fun idea to take dinosaurs out of their traditional setting and mix it up with historical fiction. ?If the story is good, I might ignore the scientific flaws about oxygen ect?mentioned in other reviews.

With that said, I don't see the conflict. It's just Teddy Roosevelt going hunting. ?I guess, my advice would be to shorten and add conflict and drama.

Good Luck!

Aside form the logic flaw that dinosaurs, as we know them, can't breath in an atmosphere containing 20% oxygen, how does him killing an animal change the country?

They got around the oxygen thing in Jurassic Park by adding modern day amphibian DNA sequences into the Pre Historic ones, but in this instance there is no convenient DNA engineering team...

Tie the destiny to the story and you are all good. ?Dinosaurs in the old west is great. ?I can see the all the standards, but subbing in dinosaurs instead of horses.
