Lambeosaurus - Drink - Day 21

Lambeosaurus magnicristatus is a giant hadrosaur from the late Cretaceous which ranged all over coastal regions of North America. They likely filled a niche similar to bovids today, as large, herd-living, migratory grazers. Many hadrosaurs, including this species, also possessed large bony crests, which probably served in display and sexual selection but which also incorporate the nasal passages, meaning that air passing in through the nostrils then traveled through the crest before exiting - and the size and shape of the crests of various lambeosaurine species probably resulted in each species having its own unique trumpet-like call for communicating with the rest of the herd.
