Quite popular with the ladies for the droop of his frill. Parasaurolophus in "All Yesterdays" mode.

Paras are my fave hardosaurs

I love the amount of detail that went into this, very realistic portrayal with the scale imprintation and the drooping frill.
He's the alpha, no doubt

The hadrosaur equivalent of erectile disfunction XD. Makes me a little sad actually.

~Tomozaurus Mar 26, 2013 Student General Artist

Incorrectly positioned hands for a hadrosaur in 2013, but nice artwork all the same.

~pheaston Mar 26, 2013 Professional Traditional Artist

How so? I am well aware that hadrosaurs did not fully pronate, which I feel the drawing reflects as I based it off Scott Hartman's skeletal.

~Tomozaurus Mar 26, 2013 Student General Artist

They don't pronate at all. Scott's skeletal was done in 2004 and is no out of date. Check the paper here: [link]

I don't know that I would use the term 'at all' to characterize the degree of pronation in hadrosaur 'hands,' as Senter clearly uses the term 'caudomedial' to describe palm orientation. That to me indicates some degree of partial (and permanent) caudal orientation. Senter certainly errs on the side of medial, even though, of the forelimb impressions in the 2 ichnological diagrams by Lockley included in the paper, 6 out of 9 are oriented more caudally than medially. I don't believe my sketch is inconsistent with Lockley's diagrams, although maybe I could have more explicitly addressed this.

And oddly, while Senter addresses the elbow articulation between the humerus and the radius and ulna, he doesn't talk enough (for my satisfaction) about the articulation surfaces between the humerus and glenoid, other than to point out the obvious disarticulation at that joint in the AMNH edmontosaur mummy. This is important, as any rotation in the humerus would necessarily affect the position of the palm, since the elbow articulation is far less mutable. And no, I'm not talking about splayed elbows.

As for Hartman's skeletals, he has a very recent revision to Gryposaurus also with semi-caudally oriented hands, so even if his parasaurolophosaur is old, he's had time to revise and either has yet to address this paper, has his own ideas about hadrosaur forelimbs, or his restorations agree with the paper.

I noticed you also used Hartman's Para. skeletal for a restoration less than a year ago, albeit before Senter's paper came out, but well after the debate about hadrosaur hand pronation was in full swing. Do you plan a revision? I might (and I'd love Scott's insight on this), but on a piece like this it would be pretty time-consuming, so I'm more than happy to leave it as is.
