yes thats right, because of the complete bodyproportion the skull has to be in my opinion a little bigger. if he was an active hunter ,it would be better for him to posses a big mouth to catch his prey.
Very well done. It looks like something I'd come across in a Greg Paul book. Professional grade. I don't know which paleontologist ceb-luv is refering to (Holtz? Carr?), but there is still mixed opinion on whether Nanotyrannus is a valid taxon, or merely a juvi T. rex. Witmer presented some scans of the Nanotyrannus braincase at the 2005 SVP meeting that showed the sinuses around the braincase (among other things) differed quite a bit from those in T. rex. These same scans were featured in a TV program on the science channel devoted to the discovery of Jane the subadult/juvenile T. rex. In his opinion (which carries a LOT of weight in the paleo community, due to the fact that he is The Man) the differences were too great to be a product of ontogeny alone. So, the matter is still up in the air. Not that ceb-luv was implying otherwise.
Cool. Hey guess what? My advisor doesn't think that Nanotyrannus is real. He believes that Nanotyrannus is infact juvenile Tyrannosaurs. And he's a theropod paleontologist so this is what he spends his life studying. I donno, I'm more interested in Sauropods than Theropods, just saying what he's been telling me. Ok, that's it. That's my little soap box.
