It describes the dinosaur’s three horns, parrot-like beak, crushing teeth, and large frill, while noting that scientists still debate the frill’s purpose. The video also explains that Triceratops lived about 66 million years ago and compares it with rhinoceroses to show how similar traits do not always mean close biological relationships.
