Charonosaurus

Charonosaurus was about 10 metres (33 feet) long and weighed around 5 metric tons (5.5 short tons). That's as long as a school bus and as heavy as a large elephant.1

Yes, scientists think Charonosaurus had a long, backward-pointing hollow crest on its head, similar to its cousin Parasaurolophus. The crest was probably used for making loud honking sounds to communicate.1

Charonosaurus was a herbivore, meaning it ate plants. It likely fed on tough vegetation like conifers, ferns, and horsetails, using its many teeth to chew.2

Charonosaurus lived at the very end of the Cretaceous period, about 66 million years ago. It was one of the last lambeosaurine dinosaurs to exist.1

Charonosaurus fossils were found in the Yuliangze Formation in northeastern China, on the south bank of the Amur River near the village of Jiayin.1

Yes, Charonosaurus lived alongside the tyrannosaur Tarbosaurus, other hadrosaurs like Amurosaurus, ankylosaurs, turtles, and crocodiles. Predators like Tarbosaurus may have hunted or scavenged Charonosaurus.1
