Natural Science Forum / Biology / Paleontology / October 2004Psittacosaurus mongolensis osteology
After searching 20 Google pages on Psicattosaurus, I have not found an osteological diagram of P. mongolenisis. Does anyone have an online reference to such information, suggestions in the literature or some scans that can be sent to me? The information is needed to assess a purportedly juvenile specimen of dubious authenticity. I appreciate the favor of any leads and will reciprocate any way I can. Regards, Edward Hennessey nohalozzyzxnohalo@noyahoo.com - no,no,no Please understand my typo corrected to P. "mongoliensis".

Your search might improve if you spelled it right: Psittacosaurus. And here's a reference that would help you: Sereno, P. C. 1990. Psittacosauridae, pages 579-592 in The Dinosauria (D. B. Weishampel, P. Dodson, and H. Osmolska, eds.), University of California Press, Berkeley. Among other things, it has diagrams of the type skeleton of your species. Are you trying to tell if it's a Psittacosaurus or trying to distinguish one species from another? According to Sereno, P. mongoliensis can be distinguished by a triangular maxillary depression and upturned lateral margin of the prefrontal. And, apparently, on some other unspecified cranial characters. > Your search might improve if you spelled it right: Psittacosaurus. > [quoted text clipped - 10 lines] > and upturned lateral margin of the prefrontal.

John: I think we both agree on the spelling of Psittacosaurus...unfortunately, I managed to mistype that generic name in the body of my message eventhough the subject heading was right. And as noted, I scored another point for manual indexterity with "mongolensis" meriting the subsequent correction it recieved.. Species differentiation was not my goal. Determining fidelity of the item to the described osteology was. Thank you kindly for your reference. A friend sent me another recent paper that addresses the matter and I have now determined and corroborated the fact that the specimen in question is a very adroit fake using some unidentified binding polymer deftly particolored to simulate bone by the inclusiion of ground bits of polymer of varying off-white shades.

OK, now I have to know. Is it a fake in that it's a doctored real fossil, and if so what? Or is it a totally manufactured fossil? |
