The distinct sets of animals in subsequent layers of ash provided evidence that their deaths were staggered. Mosel described the scene as animals visiting the waterhole, perhaps to cool off.

Beneath layers of ancient ash, evidence of two mysterious volcanic eruptions has been hiding in plain sight for hundreds and thousands of years, predating Yellowstone's last big kaboom.

The researchers studied the chemistry of ash layers created by eruptions near Quito, Ecuador, roughly 4,400 and 2,270 years ago, and modelled how much soil had accumulated between eruptions.
