The Queen of Isla Nublar...

I can not read German, but I can pretty readily use translators. Also as Sue was not found in Germany or by a German I doubt the accuracy of your source. Everything you post proves my point that birds did not descend from tyrannosaurs. They share a common ancestor that was a small dinosaur, but that is all you can say as birds fill an entirely different niche than a giant predator. I am not sure how you read that Wikipedia article but I think you should look again, or maybe find a translated version. Even if you based the T. rex on its closest related extant creatures you would get a creature much more similar to the first movie than you would the character that was developed. Comparing a distantly related dinosaur as proof that all dinosaurs were motherly is like comparing cats and dogs, cladistically. I will make this simple for you. There is no viable proof that any tyranoid was motherly to the extent they did in the movie.
