Comments on: How Vagaceratops Moved http://blogs.smithsonianmag.com/dinosaur/2010/11/how-vagaceratops-moved/ Where Paleontology Meets Pop Culture Sat, 22 Dec 2012 16:48:38 +0000 hourly 1 http://wordpress.org/?v=3.4 By: Brian Switek http://blogs.smithsonianmag.com/dinosaur/2010/11/how-vagaceratops-moved/comment-page-1/#comment-3050 Brian Switek Tue, 02 Nov 2010 14:26:00 +0000 http://blogs.smithsonianmag.com/dinosaur/?p=4203#comment-3050 Anon - Yes, a few have been found. As I said in the post, ceratopsid tracks are rare. (See this reference for some of the only tracks to be published: http://www.jstor.org/pss/4523654) The tracks showed that the dinosaurs did not have a sprawling forelimb posture, but they did not resolve the issue of whether the forelimbs were bent or not. Hopefully paleontologists will find more trackways in the future to compare to the anatomical data which has already been collected. Anon – Yes, a few have been found.

Anyway, that does not diminish the great job these people have done in reconstructing the limb posture of an ancient animal. Also, I have heard that there is still one scientist, I think based out of Wisconsin, who holds that ceratopsians held their forelimbs in a sprawling posture.
