Back when I was trying to learn them in junior high, I had to infer what I could from The Dinosauria and PDW. This is so much more useful.Mickey Mortimerhttps://www.blogger.com/profile/08831823442911513851noreply@blogger.comtag:blogger.com,1999:blog-8397350206066419382.post-59289339638904198812013-07-09T19:09:21.852-05:002013-07-09T19:09:21.852-05:00Hi Mickey, thank you for your feedback:

Also that the parietal is obviously ancestrally paired in theropods, though it fuses in some like tyrannosaurs. Finally, while you did mention the mesethmoid, readers might want to refer to Ali et al.'s (2008) excellent study of the bone in tyrannosaurids, which found it to be a fusion of sphenethmoid and mesethmoid.<br /><br />Ali, Zelenitsky, Therrien and Weishampel, 2008.
