impacts and seasonal behavior

[James Norton <jnorton@MAILBOX.UNE.EDU>]

Is there any correlation between extinction because of an impact and the
season of the year in which the impact might have taken place?  Perhaps
hibernators, migrators, etc., might have escaped if the impact had
occurred in the winter.  This may explain the survival of amphibians and
turtles, some of whom winter over in the mud at the bottom of frozen
ponds.  But then again, when it's winter in North America it's summer on
the other end of the globe, which pokes a big hole in this hypothesis.
