Reply to comment by imhereforthevotes in TIL that in 2003, scientists "resurrected" an extinct species of Ibex, bringing back one living specimen, only for it go extinct again seven minutes later when the specimen died of a lung defect by mausoliam95

We know that the oxygen concentration in the modern day is not the same as it was in the times of the dinosaurs by a significant enough amount that their respiratory systems couldn't handle it.

holy shit I didn't realize this, at least for the late Cretaceous. Maybe we need to go farther back. Imagine all the really tired dinosaurs we'd have to deal with if we brought back the most recent ones.
