The Queen of Isla Nublar...

I think you need to have a better understanding of biology and evolution before you start making statements about said fields. Yes they are both part of therapoda but this in now way means that birds are decendents of Tyrannosauridae. Therapoda is a large group of ancestrally carnivorous type dinosaurs with a tremendous amount of diversity. With in this group there is a clade Coelurosauria that both the ancestors of birds and tyrannosaurs belong to but this is where the similarities stop. Tyrannosauridae is grouped together by one major characteristic, that they possessed relatively small arms. Now do you believe that this characteristic would lead to the formation of wings? Also they were quite large and the first birds were small animals.

Show me where you found Sue was found with two offspring, because nothing I have read states this. Just to be clear you told me to check my facts first.
