Utahraptor Research, Part 6: Sexual Dimorphism

This is a bonus post. This was not originally posted on dinosaurhome.com, where I frequent.

Sexual dimorphism is the differences between a male and a female of the same species. Dimorphism comes from two Greek words: di meaning two and morph meaning form. In mallards, for example, the male has a green head and a more brilliant body than the female. In most species of spiders, the female is much larger than the male. This might have been the case for dinosaurs, as well. For example, a female Tyrannosaurus was slightly larger than a male Tyrannosaurus. In the case of Utahraptor, the female might have been a little larger than the male.
