Well, maybe, but humans can live at altitudes with about to half our normal oxygen levels, so maybe dinosaurs would have similar tolerances.

- thaumasiotes 4y agoHumans tolerate those altitudes very poorly. They suffer from health problems and miscarriages. High-altitude genetic adaptations have been the subject of a fair amount of study; there are three major groups bearing such adapations: Tibetans, Ethiopians, and Andeans. The Andean adaptation suite is noticeably more primitive and lower-quality; this is generally thought to be the result of having evolved only very recently, after humans made it to the Americas. The Tibetan suite is so effective that part of it has been proposed to be the result of interbreeding between arriving homo sapiens and a different hominid species native to the Tibetan plateau.
- BurningFrog 4y agoThanks. I didn't know Ethiopians were also in the altitude mutant club! My anecdote is I travelled in Bolivia for 3 weeks. Never under 3700 meters. One day we climbed Uturunku (6008 meters) as part of a jeep tour, You start at 5100 meters, so it's less crazy than it sounds. Of the 6 tourists starting, only 3 made it up, with some real struggles. Meanwhile, our native guide seemed to just have a relaxing walk...
