No mere river flood could account for so many casualties. So, the researchers proposed that the cause was something much more violent.

Earth's surface shows features that clearly testify to some kind of catastrophic event, or series of events, that operated on a vastly larger scale than today's geologic processes. Whatever happened had a devastating impact on living creatures large and small, terrestrial and marine.

The blindsnake, a small subsurface burrower, is not often seen, but when it is many mistake it for a worm.¹ Researchers have constructed an evolutionary history for these creatures, partly from biological data and partly from evolutionary assumptions.
