Talk:Nash and Ramsey/@comment-35529990-20190621081809

For the trivia, "Despite being the youngest, Nash is taller than Ramsey, despite the fact that females are actually larger than males in real life." This is very weakly supported. This generalization was made based on Birds of Prey (where the females are generally only larger so they can fly when they're carrying eggs). There is only one or two tyrannosaur specimens we know the gender of, one of them being B-Rex, who was found with Medullary tissue, which is only found in pregnant birds.

For a while it was thought that the "Robust" and "Gracile" skeleton morphs that Gregory S. Paul refers to were expressions of this dimorphism, however the two skeletons represent a gradient over the course of time rather than being mixed together as you'd expect of those living at the same time.
