How did a 30-foot duck-billed dinosaur blast low-frequency calls across North American prehistoric forests? In this comprehensive deep-dive into Parasaurolophus walkeri, we explore its initial 1920 discovery in Alberta, debunk the long-standing 'snorkel' myth through modern CT scanning, examine its hundreds of self-sharpening teeth, and hear the supercomputer acoustic simulations that brought its haunting voice back to life 75 million years later.
