Velociraptor calls became iconic through Jurassic Park in 1993, where the film portrayed raptors as intelligent pack hunters that chirped, barked and screeched to communicate. Those vocalisations were not real dinosaur recordings, since no such recordings exist, but designed sound effects built to feel animal, clever and threatening. As clips from the films spread online, the calls became shorthand for any dinosaur scene in edits, games and memes. Creators still reuse them today because a few seconds of chirping instantly signals a raptor is nearby, even in completely unrelated footage.
