Here I am with Sue, the world’s largest Tyrannosaurus Rex. We share the same name, but I don’t think that we look very much alike. Consider: She is a dinosaur; I am a mammal. She is the world’s largest; while I could lose some weight, I am not the largest anything. She has been dead for some time. I am quite alive.
On the other hand, we are both bipeds.
These pictures were taken at the Field Museum in Chicago.
