Pachycephalosaurus skull domes have intrigued us for decades and many palaeontologists think that they're an example of an intraspecific combat weapon.

Musk oxen even have a domed region on the tops of their skulls that resembles the domes of Pachycephalosaurs and is used as a battering ram during intraspecific combat.

We have some other great examples of intraspecific variations in our zoology museum.

Many dinosaur species probably had a variety of offensive and defensive weapons that were adaptations for intraspecific combat.

许多物种可能拥有各种适合种内战斗攻击性和防御性武器。

We have to consider sources of morphological variation that might simply be differences within a species, which we call intraspecific variation.
