Harry Pristis Posted March 11, 2008 Share Posted March 11, 2008 Nice dino pix in your album, Geofossil. Will you be adding scale and more data on the fossils in the pix? I'm curious about the currently-third image IMAGE HERE in which you illustrate a "pleurocoel". Can you tell us what is the function of a pleurocoel in the cervical vertebrae of sauropods? I had never heard the term till I saw your image. Thanks! -------Harry Pristis http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
micropterus101 Posted March 17, 2008 Share Posted March 17, 2008 I dont know for sure but I am guessing it is where a nerve comes out of the vertebrae? fossil crabs website Link to comment Share on other sites More sharing options...
Harry Pristis Posted March 17, 2008 Author Share Posted March 17, 2008 I dont know for sure but I am guessing it is where a nerve comes out of the vertebrae? It may be more than simply a nerve foramen.

ebrocklds Posted March 17, 2008 Share Posted March 17, 2008 i heard a talk by Phillip Currie that he believes that the hollowness of the bones were used as a pneumatic system that could be used to lighten the skeleton and also as a shifting balance. there are many hollow spots in therapods and suaropods that i understand would be interconnected to form this pneumatic air system. there are several papers that he has published talking about some of these apects he also says this "One of the most important similarities (to birds) would be their one-way system of breathing. “Birds have a very unique way of breathing,” Dr. Currie said. “They are always exchanging carbon dioxide and oxygen.” They have small air-filled tubes in their hollow skeletons. Tyrannosaurs have such hollow, air-filled bones." i found this on this page http://www.rmdrc.com/science/Phil%20Currie%20article.doc i thought that it was very interesting enjoy Brock Link to comment Share on other sites More sharing options...
