Fossil discovery reveals dinosaur vocal secrets

A new fossil discovery suggests the origins of birdsong may date back to dinosaurs.

Fossil discovery hints at dinosaurs having birdlike calls

Researchers recently announced the discovery of Pulaosaurus, a fossilized herbivorous dinosaur, in northeastern China. This dinosaur, which lived 163 million years ago, had a throat structure similar to that of modern birds, hinting that birdsong could have ancient origins. The nearly complete skeleton shows how this creature fit into the evolutionary lineage leading to duck-billed and horned dinosaurs. While no soft tissues were found to clarify its vocal capabilities, the discovery challenges common perceptions of dinosaur sounds.

The finding of Pulaosaurus adds a fascinating chapter to our understanding of dinosaur vocalization. Traditionally, we have viewed dinosaurs as loud and aggressive creatures, often depicted growling in films. This discovery compels us to rethink their capabilities and behaviors. If dinosaurs could produce birdlike calls, it opens up new inquiries into their social interactions and environmental adaptations. The nuances of this discovery may reshape paleontological narratives around dinosaur behaviors, indicating a more complex ecological role.
