1. Three-Horned Face: The name Triceratops actually comes from ancient Greek words that mean "three-horned face." It had two long horns above its eyes and one smaller horn on its nose!

2. A Shield for Protection: Behind those famous horns was a giant, bony frill attached to its head. Scientists think this frill acted like a built-in shield to protect its neck from hungry meat-eating dinosaurs like the Tyrannosaurus rex.

3. Built Like a Tank: Triceratops was a massive plant-eater. It could grow up to 30 feet (9 meters) long—about the length of a large school bus—and weighed as much as a heavy-duty pickup truck!

4. Hundreds of Teeth: Even though it didn't eat meat, a Triceratops had an amazing mouth filled with up to 800 teeth! They were stacked in columns so that when old teeth wore down from chewing tough plants, new ones would take their place.

5. Beak Like a Parrot: Instead of regular front teeth, a Triceratops had a sharp, curved beak made of keratin (the same stuff as your fingernails) that it used to snap off tough palm fronds and cycads.

6. Walking in Herds: Fossil evidence suggests that Triceratops may have traveled together in family groups or herds, which helped protect the younger dinosaurs from predators roaming the prehistoric plains.

7. Fossil Treasures: The very first Triceratops fossil (specifically its huge horned skull) was found in Colorado in 1887 by a fossil hunter named John Bell Hatcher, and it has been one of the world's most popular dinosaurs ever since!
