## Curiosity - Did you know?

For decades, scientists erroneously believed the bizarre crest functioned as a snorkel for underwater foraging. Modern paleontology has thoroughly debunked this cinematic myth. The internal nasal tubes lacked a top opening, making the **snorkel hypothesis** biologically impossible. Instead, the size and shape of this extraordinary biological instrument varied drastically based on age and sex—a clear example of **sexual dimorphism**. Females and juveniles possessed much smaller crests. The towering tubular antenna of mature males served a dual purpose: amplifying their thundering calls and acting as a vibrant billboard to advertise genetic maturity during courtship displays.
