This video’s about the maybe-you’ve-seen-it-before Parasaurolophus.
With a body length of 10 meters, and a humble, yet dignified appearance, this herbivorous dinosaur has indeed piqued our interest.
For this creature has one incredibly distinguishing feature: the 1-meter-long crest crowning its head.
Why did the Parasaurolophus wear this crown? Wouldn’t it have been uncomfortable?
Well, it’s about time we explore the SCIENCE behind Parasaurolophus’ cranial crest!
