  It has been suggested before that a radio-active cloud could have
been the cause of the extiction of large anamals; large animals will
suffer greater damage from gamma or other hard radio-active exposure
and to the reasons you stated (close to the ground, or in a burrow
out of the line of direct exposure). this is a pet project of mine
and its very intriguing. any input to me would be very welcome.
                                      Have a good day.
