(Well guys, here’s the one of 4 dinosaurs that always appear in the Jurassic Park films, the others include T.Rex, Velociraptor and Triceratops.)
Parasaurolophus Walkeri is one of the most well known of the hadrosaurs, or duckbill dinosaurs. Parasaurolophus’s most noticeable feature, it’s long tubular crest has been hypothesized to have been used for. It was once believed that the crest was used like a snorkel underwater, but this hypothesis has since been closed due to the fact that there was no opening at the top of the crest to help the dinosaur breathe underwater. Now we know that the crest was actually used during vocalization, and helped to identify each individual of the herd.
