Ancient Wounds Reveal Triceratops Battles
Source: ScienceDaily
ScienceDaily (Jan. 28, 2009)

How did the dinosaur Triceratops use its three horns? A new study led by Andrew Farke, curator at the Raymond M. Alf Museum of Paleontology, located on the campus of The Webb Schools, shows that the headgear was not just for looks. Battle scars on the skulls of Triceratops preserve rare evidence of Cretaceous-era combat.

"Paleontologists have debated the function of the bizarre skulls of horned dinosaurs for years now," said Farke. "Some speculated that the horns were for showing off to other dinosaurs, and others thought that the horns had to have been used in combat against other horned dinosaurs. Unfortunately, we can't just go and watch a Triceratops in the wild."

If Triceratops fought each other with their horns, wounds from this combat would be preserved in the fossil bones. So, Farke joined forces with paleontologists Ewan Wolff of the School of Veterinary Medicine at the University of Wisconsin and Darren Tanke of the Royal Tyrrell Museum of Paleontology in order to search museum collections throughout North America for evidence of these injuries. The researchers focused on the skulls of Triceratops and a closely-related dinosaur, Centrosaurus.

"If Triceratops and Centrosaurus only used their horns and frills for showing off, we would expect no difference in the rate of injury for both animals," stated Farke. Instead, the team found that the squamosal bone, which forms part of the frill, was injured 10 times more frequently in Triceratops than in Centrosaurus. He added, "The most likely culprit for all of the wounds on Triceratops frills was the horns of other Triceratops."
