Long-crested Parasaurolophus

The better known species, P. walkeri. Some think that this and P. cyrtocristatus are the same species, although there are stratigraphic reasons to question this.

Edit: Most of my updates I'll let slide by without a notice, but there's a major shift in restored stance coming in hadrosaurs. Research I've done (some of which I covered in my 2004 SVP talk) shows that the shoulder blades of hadrosaurs sit further down (and generally more horizontal) on the ribcage than they do in other dinosaurs. This has several cascading impacts on how the stance of hadrosaurs is restored, as well as the torso musculature.

The short version (for now) is that duck-billed dinosaur tails do not stick up wildly into the air, as I and others had restored in the past. This also is important in terms of muscle leverage and efficiency during locomotion.

Enjoy!

Edit 11/30/2018: More changes to the forelimbs, and some tweaking to the silhouette (this one had seen more updates than some of my other hadrosaurs, so there was less to do).
