If we cloned a dinosaur today would it die quickly due to the lower oxygen content in the air today?

Oxygen content today isn't actually much different than that at the time of the dinosaurs.  Over the millions of years they were alive, it was sometimes higher and sometimes lower.  It's the giant insects of the Carboniferous which were really dependent on high oxygen levels.
