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


-Duller colors

-Smaller dewlap



-Brighter colors around the eyes

-Larger dewlap

-More rough-looking face



Many people think that female Tyrannosaurus were larger than males because of the hypothesis proposed by the heavily-outdated but still phenomenal Walking With Dinosaurs.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.

Once again the male rex is legendary.

Good grief.

Like your speculative designs. Also, I didn't know that female T. Rex's weren't bigger than the males.

Godzilla... Truly a God incarnate.
