(Speculative) Tyrannosaurus rex Sexual Dimorphism

As with many animals today, Tyrannosaurus rex likely had sexual dimorphism. Here is my concept for how males and females would be differentiated:

Female

-Duller colors

-Smaller dewlap

 

Male

-Brighter colors around the eyes

-Larger dewlap

-More rough-looking face

-Scars

 

Many people think that female Tyrannosaurus were larger than males because of the hypothesis proposed by the heavily-outdated but still phenomenal Walking With Dinosaurs. There's no evidence to support that females were larger. The sizes of Tyrannosaurs probably varied based on the individual, determined by factors such as nutrition, health, nourishment, and fitness. Let me know what you think below.
