Triceratops horridus

Brow horn

This horn is 28 inches long and 23 inches in circumference near the base. It is from the Cretaceous age Lance Formation of Wyoming. Just look at all of the blood grooves on this fantastic horn. Like antlers and horns on modern day mammals, Triceratops horns were probably used more for show (and thus mate selection) than for defense. But if you would rather forget we said that and instead reminisce on the more romantic “T. rex versus Triceratops” concept, we'll understand. And it’s important to remember that much speculation goes into recreating the life of dinosaurs so Triceratops may have indeed defended itself with those massive, reinforced horns. Triceratops of course had three horns, two on its brow and another smaller horn behind its snout. When you hold these giant bones in your hands, consider that only the inner cores are preserved as fossils. In life, these structures would have been sheathed in a hard, shiny horn.
