rfossils Posted September 6, 2009 Share Posted September 6, 2009 (edited) This is a cast of a Pachycephalosaur dinosaur called a Dracorax hogwartia (Upper Cretaceous, Hell Creek Formation, Montana). I found the original skull. I have pics of the most of the original material. One partial upper skull and my skull are the only known specimens of this dinosaur. The incisors are serrated on the skull I found and raises the question of whether Dracorax were herbivores, carnivores, or omnivores. Bob Bakker did the original description. http://img137.imageshack.us/img137/1149/picturesj.jpg Below are pictures of original portions of the skull.

MikeD Posted September 6, 2009 Share Posted September 6, 2009 Welcome to the forum. I saw your Phyllacanthus pic on Lance's forum. Thought your avatar looked familiar. I saw a replica of the skull at the HGMS show. Very cool to see pics of the original. Link to comment Share on other sites More sharing options...

Frank Menser Posted September 6, 2009 Share Posted September 6, 2009 Now I'm heart broken.. Tried pull up your pics and got a "503-no server" message. At least the casting looks good. I can see the confusion though, the teeth look predator but why all the armor? Be true to the reality you create. Link to comment Share on other sites More sharing options...

lordpiney Posted September 7, 2009 Share Posted September 7, 2009 beautiful skull. wasnt that the same one on the cover of the national geographic magazine from last year? Link to comment Share on other sites More sharing options...
BobC Posted September 7, 2009 Share Posted September 7, 2009 Wow--that is the discovery of a lifetime. Congratulations!! But I don't get the comment about it being an omnivore,carnivore or omnivore--isn't that all there is? Was Bakker saying this guy ate everything, in which case that would make him an omnivore, right? I feel like I'm missing something. Those teeth look carnivore to me. Link to comment Share on other sites More sharing options...
Auspex Posted September 7, 2009 Share Posted September 7, 2009 ...The incisors are serrated on the skull I found and raises the question of whether Dracorax were herbivores, carnivores, or omnivores... How about piscivorous? the individual tooth morphology has similarities to croc, gator, even mosasaur. They'd also work on small terrestrial critters ("one-gulp snacks"). In any case, it's not well equipped to be a vegetarian...

BobC Posted September 7, 2009 Share Posted September 7, 2009 Oops. I misread that. Sorry. Regardless, those look like carnivore teeth to me. Link to comment Share on other sites More sharing options...

Boesse Posted September 8, 2009 Share Posted September 8, 2009 Nice find. sharp teeth don't always make a predator. Other pachycephalosaurs, and many ornithischian dinosaurs have sharp and sometimes caniniform teeth. I should note that a few folks have raised some pretty good points, including one of the co-describers (Robert Sullivan), that "Dracorex" very likely represents a juvenile Pachycephalosaurus, and that Stygimoloch is a "subadult" Pachycephalosaurus. Other marginocephalians (i.e. ceratopsids) completely reshape their face during ontogeny. Bobby Link to comment Share on other sites More sharing options...
