*New research suggests that the iconic dome-skulled dinosaurs known as pachycephalosaurs may have used their thick skulls to smash into each other during courtship or combat.*
Pachycephalosaurs were a group of herbivorous dinosaurs that lived during the late Cretaceous period. They were characterized by their thick, dome-shaped skulls, which were often adorned with bumps and ridges. These skulls have long been thought to have been used for defense, but a new study suggests that they may have also been used for social interactions.
The study, published in the journal *Current Biology*, used computer simulations to model the forces involved in head-butting between pachycephalosaurs. The results showed that even relatively small, teenage pachycephalosaurs could generate enough force to fracture the skulls of their opponents. This suggests that head-butting may have been a common form of aggression among these dinosaurs.
The researchers believe that head-butting may have been used for a variety of purposes, including courtship, territorial disputes, and dominance hierarchies. It is also possible that head-butting was used as a form of play among juveniles.
The study's findings provide new insights into the behavior of pachycephalosaurs and help to shed light on the evolution of social behavior in dinosaurs.
Pachycephalosaurs were a group of ornithischian dinosaurs that lived during the late Cretaceous period. They were characterized by their thick, dome-shaped skulls, which were often adorned with bumps and ridges. Pachycephalosaurs ranged in size from small, bipedal forms to large, quadrupedal forms. The largest known pachycephalosaur, *Dracorex hogwartsia*, was about 9 meters (30 feet) long and weighed about 4,500 kilograms (10,000 pounds).
Pachycephalosaurs were herbivores, and their diet consisted mainly of plants and fruits. They lived in a variety of habitats, including forests, grasslands, and deserts. Pachycephalosaurs were social animals, and they lived in herds of up to several hundred individuals.
The dome-shaped skull of pachycephalosaurs has long been a mystery to paleontologists. Some researchers believe that the skull was used for defense, while others believe that it was used for courtship or combat.
The new study suggests that the dome-shaped skull was used for a variety of purposes, including courtship, territorial disputes, and dominance hierarchies. It is also possible that head-butting was used as a form of play among juveniles.
