Triceratops roars are a staple of dinosaur sound libraries, created by sound designers layering animal vocals and effects to imagine what a horned dinosaur might have sounded like, since no real recording exists. Clips like this one circulate widely on soundboards and in creator projects because they are short, punchy and instantly recognisable as a dinosaur. They are commonly used in educational videos, games, animations and memes about prehistoric life, where a single roar can establish a creature without dialogue or explanation.
