Parasaurolophus Near a Waterfall in a Prehistoric Environment
The scene displays a Parasaurolophus situated beside a river and a flowing waterfall surrounded by a prehistoric forest. Large river valleys provided abundant plant life and steady water sources for herbivorous dinosaurs during the Late Cretaceous period. Lush vegetation grew along damp riverbanks where waterfalls created mist and fertile soil.
Discoveries About the Parasaurolophus Crest
The distinct long tubular crest extending from the back of the skull contained hollow nasal passages connected directly to the dinosaur nostrils. Scientists believe Parasaurolophus used this crest as a natural resonance chamber to produce low-frequency acoustic calls that traveled across long distances. Computer models recreating air movement through the skull suggest these vocalizations sounded similar to a foghorn or brass instrument.
