How Scientists Recreate the Sounds of Dinosaurs: New Discoveries Change the Roar

Scientists Use Modern Animals to Recreate Dinosaur Sounds The mystery of dinosaur sounds has long captivated researchers. Recent fossil discoveries, coupled with comparisons to modern-day birds and crocodiles (their closest living relatives), are providing new insights. A recent video by BBC highlights this research, showing how scientists use these comparisons to recreate plausible dinosaur vocalizations. "Birds and crocodiles can help us guess what sound a dinosaur would have made," explains the narrator of the BBC video. The video uses examples of Tyrannosaurus Rex and other dinosaurs to illustrate how their sounds have been recreated using a combination of big cat roars, crocodile bellows, and other sounds. The video also contrasts the sounds used in the 1999 "Walking with Dinosaurs" series with the more current, scientifically-informed versions. This comparison highlights the evolution of our understanding of dinosaurs and how new discoveries continue to refine our understanding of these prehistoric creatures. The discovery of a fossil brain case in Utah, for instance, provides further clues about dinosaur intelligence and social behavior, which impacts the assumptions made about their sounds. The video concludes by stating that while we may never know exactly how dinosaurs sounded, we now have a much better idea, thanks to advancements in paleontology and comparative biology.
