    I read somewhere that if we could bring back a dinosaur, it wouldn’t survive long, because of the oxygen concentration in our atmosphere. Is it true?

      I may have heard a similar thing on a video that compared an elephant sized mouse with a mouse sized elephant.

      Neither could survive because evolution designed their bodies for the relative pressure they exist in. This is also related to how fast their hearth beats go.

      Human sized bugs could not exist for the same pressure reason also.

      Depends. Something from 125 to 200 millions years ago would probably struggle. Maybe you can put them on a mountain? But that’s probably too cold. But again, Jurassic Park dinosaurs are a mix of animal DNA, contemporary and older.
