[Doctor Stochastic]

Who would not expect a significant flood every 100 years or even every 500 years?

Those living in deserts. Or on the ocean.

Doc: "Those living in deserts. Or on the ocean."

But of course the topic was equines, and most people would argue that equines inhabit neither of those places...

Besides, the fact that one equine is found in a foot of sediment would imply that condition could re-occur in the same vicinity (like a flood plain, perhaps?).
