Parasaurolophus was a “duck-billed” dinosaur known for its distinctive hollow head crest, which scientists think might have been used to make distinctive sounds. It lived in what is now western North America, from Alberta to New Mexico. The model was made with driftwood, hickory nuts, cork bark, shelf fungus, elm bark and Indian redwood fruit.

Taken at the US Botanic Garden’s annual holiday display, this year titled ‘Season’s Greenings: Dino-Mite!’. Model trains run on several tracks around the exhibit area.
