These coprolites, found in places like the Yukon, contain DNA from a surprising variety of animals—including snowshoe hares, bison, sheep, wolves, and coyotes—revealing that these tiny rodents were opportunistic eaters building fat reserves for hibernation. Combined with volcanic ash layers, the droppings offer precise snapshots of life 70,000 years ago. As DNA analysis improves, researchers expect even deeper insights into ancient species interactions and…
