趣味知識

Iguanacolossus was a styracosternan, a group of iguanodont dinosaurs that often had thumb spikes.1

Its fossils were found at a site called Don's Ridge in Utah, named after the discoverer Don DeBlieux.1

Only one skeleton of Iguanacolossus has been found, including parts of the skull, backbone, and hips.1

Iguanacolossus lived during the Early Cretaceous period, when Utah was a warm, dry land with rivers and forests.1

Scientists think Iguanacolossus was about 9 meters (30 feet) long, as big as a school bus.1

It had a special sinuous (wavy) contact on its skull that is unique to this dinosaur.1
