Hadrosaur

Hadrosaur was a family of dinosaurs that were native to what was eventually known as Asia, Europe and North America during the Mesozoic Era.

By the 20th century, this type of dinosaur was believed to be extinct for millions of years, but at least one was still alive in the 1970s, living in the underground jungle of Molesville, which could be accessed via Bottomless Cave.
