RE: impact - LONG

I guess it depends on what we define as large, but I think you're
correct.  There were 20 ft. crocodilians around after that time,
but I'm not sure of the date; there may have been a gap.  But 
6 meter ones were certainly around 25 million years ago.  Of course, that's
a LONG time after KT.
