Unlike most of the Iguanodonts who preferred living in open woodland, this animal lived in the Antarctic/Australian jungle, where its coloration would've blend in, as shown in the series.
Muttaburrasaurus lived in Australia and Antartica during the Middle Cretaceous period, over 106-95 million years ago. It shared the environment with Australovenator, Leaellynasaura, and even the giant amphibian Koolasuchus. The species was initially described from a partial skeleton found by grazier Doug Langdon in 1963 at Rosebery Downs Station beside Thomson River near Muttaburra, in the Australian state of Queensland, which also provides the creature's generic name.
During the Middle Cretaceous period in Antarctica, Muttaburrasaurus was known as the largest of all the summer migrants. It was a 9 metered long, 3 ton herbivorous dinosaur. It made trumpeting calls as a means of herd communication. It is thought that it was a migratory animals, moving North and South with the changing seasons. It was the largest summer migrant, by a considerable margin.
BehaviorEditLike other herbivores, Muttaburrasaurus lived in huge herds. Every year, herds of Muttaburrasaurus migrated 800 kilometers down the coast of Australia to find secure sights to lay their eggs in Antarctica. With each massive adult weighing about three tons, they could pluck food from branches several meters off the ground. While feeding, the dinosaurs kept in touch using the specially adapted noses to produce a range of trumpeting calls, similar to an Elephant. These herbivores were slow, but they found safety in size and numbers. Occasionally, these giant migrants got lost in the forest.
- The sound effects of Muttaburrasaurus are that of elephant trumpets as well as camel, moose, seal, walrus, and hippo sounds.
