Computer simulations reveal how horned dinosaurs used headgear during ancient combat

New three-dimensional computer simulations show that the skulls of ceratopsians, or horned dinosaurs, were structurally adapted to handle specific forces during combat. Science News reported that researchers modeled 3-D skulls from five different species of ceratopsians to test the biomechanical limits of their headgear. The findings indicate that different species used distinct fight tactics based on their unique skull architecture. [1]

According to Science News, the massive skull of Triceratops was structured specifically for horn-to-horn grappling and could handle the strain of interlocking horns during battles. In contrast, the simulations showed that Centrosaurus, a dinosaur resembling a modern rhinoceros, had a skull capable of withstanding the vertical strain of stabbing its nose horn up and down. [1]

Not all species examined were suited for physical conflict. Science News reported that the smaller, parrot-faced Psittacosaurus possessed a head that was ill-suited to withstand heavy blows, suggesting it likely avoided direct fights entirely. These mechanical simulations help researchers reconstruct how ancient combat methods influenced the evolutionary design of dinosaur skulls. [1]

A horn is defined as a permanent pointed projection on the head of an animal, consisting of a keratin sheath surrounding a core of live bone. Unlike temporary antlers, true horns remain attached throughout the life of the animal. [2]
