Dinosaurs may not have roared like lions; instead, their sounds were likely much weirder and more complex. Scientists are piecing together ancient vocalizations using fossil evidence, despite the challenges posed by the lack of sound-producing structures. Unique dinosaurs like Parasaurolophus might have communicated in ways Hollywood doesn’t portray. Innovative sound design techniques are employed to recreate these sounds, drawing inspiration from modern animals. The podcast also dissects how popular media often misrepresents dinosaur sounds, blending creativity with scientific inquiry.

Quick takeaways
Reconstructing dinosaur sounds is challenging due to the rarity of fossilized soft tissues, requiring comparisons with modern birds and crocodilians.
Anatomical variations among species, such as the Parasaurolophus's unique head structure, indicate diverse communication methods and sound production capabilities in dinosaurs.

Reconstructing Dinosaur Sounds
Understanding what dinosaurs sounded like poses significant challenges due to the limited fossil record. Fossils of sound-producing structures, primarily made of soft tissues, are rare and often do not survive the fossilization process. Paleontologists have found only one dinosaur for every 10,000 years during their existence, complicating efforts to gather enough data to draw conclusions about their vocalizations. Researchers explore methods like examining closely related species, such as modern-day birds and crocodilians, to reconstruct potential sound-making organs of dinosaurs.
The Role of Sound Design in Media
Sound design plays a critical role in how dinosaurs are portrayed in film and media, often relying heavily on a mixture of animal sounds for dramatic effect. For instance, the iconic T-Rex roar from the Jurassic Park series was actually created by blending various mammal sounds including those from tigers, elephants, and even dolphins. However, modern productions like Prehistoric Planet are taking a more scientifically informed approach, shunning the use of mammal sounds and focusing on the potential sounds of crocodiles and birds. This shift highlights the collaboration between scientists and sound designers to evoke a more accurate auditory representation of dinosaurs.
Specific Dinosaur Vocalizations
Some dinosaur species, like the Parasaurolophus, provide a clearer understanding of their vocal capabilities due to unique anatomical structures, such as the hollow tube on their heads. This structure would have allowed them to produce low-frequency sounds, resonating much like a foghorn or a tuba. In contrast, the brachiosaurus is theorized to have had a much softer sound, potentially resembling a hiss because of their long necks and the difficulty in producing loud vocalizations. This difference illustrates how the anatomy of each species may have fundamentally shaped their communication methods.
The Evolution of Sound in Dinosaurs
The evolutionary connection between dinosaurs and birds raises intriguing questions about the sounds dinosaurs may have made. Birds possess a unique vocal organ called a syrinx, which allows them to produce complex sounds, and recent discoveries suggest this organ might date back further than previously thought. Scientists speculate that if dinosaurs had similar vocal capabilities, they might have produced more complex sounds, including potential songs or distinctive calls. While reconstructing these sounds is speculative due to the limitations of fossil evidence, ongoing research and emerging discoveries continue to enhance our understanding of ancient vocalizations.
They probably didn’t roar like lions. Their real voices were likely much, much weirder. We asked scientists to help us re-create these strange, extinct sounds. (First published in 2022)
