These features all date to this same time period, and no other process explains how they all have the same orientation (NW-SE). No impact bodies have ever been found, which is consistent with a comet. As we all saw with Shoemaker Levy when it hit Jupiter, comets can fragment into many smaller pieces.

I vote for ice storm! :D Another controversial theory : ice age isn't enough? Same for Xinavera's third theory, the overkill hypothesis. The most coherent theory today is simply climate change.

Second, comet impacts don't necessarily leave craters. Tunguska (which was probably a comet) knocked down a lot of trees, but didn't make a crater. Third, megafauna extinctions were probably due more to human hunting than astronomical events. We've seen this in Australia, New Zealand, and North America. Intriguing, but a couple points:

Would the coment shower them with snow or with fire? That dosn't explain how some mammoths have been traped in ice. Would the coment shower them with snow or with fire?
