Presumably this could work for dinosaur juveniles too.  I realize that
they would grow more quickly and therefore require more bulk sooner.  But
what we are doing now is stipulating a length of time for the bolide's
effects.  It's got to be long enough to kill dinos, short enough to allow
croc survival.  This would seem a very narrow (i.e., unlikely) window of
opportunity for crocs.  And what was it about this particular length of
time that allowed for bird and mammal survival?  And, in any case, if we
are moving into a "nuclear winter" model, insect production is going to be
very low.
