Why did dinosaurs probably not pee in the Grand Canyon?
That’s likely because what is now the Grand Canyon was once a series of smaller canyons that joined through slow, massive process of erosion. While parts of the canyon began eroding 70 million years ago, most of the key integration happened much, much later.
