It may have had loose skin around its nose area - some paleontologists think that it may have been able to blow up this skin like a balloon, perhaps for mating rituals or intra-species rivalry. It had a series of bumps (tubercles) running along its neck, back, and tail.

The fossil found was approximately 30 feet long, which leads us to believe the dinosaur in this discovery was almost a mature adult.
