It seems to me the main problem people are raising here is that
the female dinosaur would have a problem supporting the weight of
the male dinosaur as well as her own. It seems to me that the male dinosaur
would be fairly good at supporting his own weight. If the female
lowered herself to her knees it would be quite possible for the male
to be positioned above the female without adding too much if any
Of course if they activity was particularly vigorous, or the male was
startled during the act, an innapropriate movement of that amount of mass
could damage both of the animals involved, thus explaining the broken
sauropod tail. However not all animals mate in a vigorous manner and
this would probably be selected against with particularly large animals.
The males may also have been significantly smaller than the females as is
postulated for the T-rex, which would reduce the problem further.

Some of the more environmentally aware dinosaurs were worried about the
consequences of an accident with the new Iridium enriched fusion reactor.
"If it goes off only the cockroaches and mammals will survive..." they said.
