Its remains were found in [[China]]. The partial skull resembles that of ''[[Parasaurolophus]]'' from North America. This does ''not'' suggest a [[Bering land bridge]] existed during the Cretaceous period, since at that time North America was far away from Eastern Asia. Instead, it is likely that this group of hadrosaurs all had a similar long, backward-projecting hollow crest. It may have been used for trumpeting their calls. In other words, their skull shape was a [[basal]] feature. ''Charonosaurus'' was a very large [[Lambeosaurinae|lambeosaurine]] hadrosaur (estimated around 13&nbsp;m (42.5&nbsp;ft) long),<ref name = charonosaurus>{{cite web|url=http://www.luisrey.ndtilda.co.uk/html/charno.htm|title=Charonosaurus|access-date=2012-04-07|archive-date=2009-07-07|archive-url=https://web.archive.org/web/20090707063324/http://www.luisrey.ndtilda.co.uk/html/charno.htm|url-status=dead}}</ref> known from a partial skull found in [[Heilongjiang Province]], northeastern China. Adult and juvenile hadrosaur remains were found in the same area. They give information on the rest of the skeleton; the femur length was up to 1.35 m. (4.5&nbsp;ft). ==In popular culture== ''Charonosaurus'' was featured in the [[Discovery Channel]] television documentary [[The Last Day of the Dinosaurs]], where it was the prey of ''[[Troodon]]''. == References == {{Reflist}} [[Category:Hadrosauridae]] [[Category:Cretaceous dinosaurs]]
