The Triceratops is a well-known dinosaur species that roamed the earth during the Late Cretaceous period, approximately 68-66 million years ago. One of its most distinctive physical features was its large, three-horned skull. The Triceratops had two large brow horns that protruded from its frill, along with a shorter nasal horn on its snout. The brow horns of the Triceratops are particularly fascinating and have been the subject of much research and speculation over the years.
 
The brow horns of the Triceratops were formidable structures that could reach up to three feet in length in some specimens. They were made of solid bone and were firmly attached to the skull. Scientists have debated the purpose of these impressive horns for decades. Some have suggested that they were primarily used for defense against predators, while others believe they may have played a role in mate selection or intraspecies competition.
 
Recent studies have shed new light on the function of the Triceratops brow horns. Research has shown that the horns were likely used for both defense and display. CT scans of Triceratops skulls have revealed that the brow horns were highly vascularized, meaning they had a rich blood supply. This suggests that the horns were used in thermal regulation, helping the dinosaur to dissipate excess heat during hot weather. Additionally, the shape and size of the brow horns may have been used to intimidate rivals during intraspecies conflicts, making them an important part of the Triceratops' social behavior.
