JohnJ Posted October 2, 2011 Share Posted October 2, 2011 Not sure of the species, but it is a cervical vertebra that is very close to the skull. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
sward Posted October 2, 2011 Share Posted October 2, 2011 Mosalover, I'm not sure what someone from The Netherlands was doing in Arkansas, but it looks like it was a very successful trip (at least if you were looking for fossils). Nice find. I only wish I could find such a nice vert. BRGDS sward DFW, TX SWardSoutheast Missouri (formerly Dallas/Ft. Worth, TX) USA Link to comment Share on other sites More sharing options...
Mosalover Posted October 2, 2011 Author Share Posted October 2, 2011 Hi all, I will try Mike Everhart. If i get an answer i will let you know, all the best! Link to comment Share on other sites More sharing options...
Roz Posted October 2, 2011 Share Posted October 2, 2011 It looks like a possible Halisaurus vert to me... Yes, please check with Mike.. He would know.. Very, very nice! Welcome to the forum! Link to comment Share on other sites More sharing options...
Mosalover Posted October 2, 2011 Author Share Posted October 2, 2011 It is interesting, i have a cervical vertebra Prognathodon giganteus and it is about the same size. So maybe it is not halisaur but a bigger species. Doesn't matter to me of course. We will see what Mike brings us.... Link to comment Share on other sites More sharing options...

FossilDAWG Posted October 7, 2011 Share Posted October 7, 2011 I think I'd go with Halisaurus as well. The rounded surface that articulates with other vertebrae is conspicuously shorter top-to-bottom than it is side-to-side, which is a typical Halisaurus feature. In other mosasaurs the dimensions are more nearly equal. I'll be interested to hear what Mike Everhart has to say. I'm still just learning about how to ID mosasaur vertebrae myself.

Don Hi all, Mike Everhart forwarded the pics to Mike Polcyn, Mike: here is the answer! > Hi all, > It is definitely Plioplatecarpus sp. . Mid-cervical ( C4 or C5?) We have multiple quadrates, other skull parts, and quite a bit of postcrania (including limb material) from this taxon (thanks to Kelly). I have compared to the type material of P. primaevus and there are differences, so I will only refer to Plioplatecarpus sp. at this time. > Mike > > Mike Polcyn > Roy M.

FossilDAWG Posted October 8, 2011 Share Posted October 8, 2011 Thanks for the update. As I said, I'm learning about these vertebrae, and I thought Halisaurus was the only one with dorso-ventrally compressed vertebrae. Now I know otherwise. What a beautiful specimen too! You must have been thrilled to find that. Don Link to comment Share on other sites More sharing options...
Mosalover Posted October 9, 2011 Author Share Posted October 9, 2011 (edited) As a mosalover i,m still totally thrilled by my halisaurus arambourgi jaws, there from Khouribga Morocco. Hope you like it. Edited October 9, 2011 by Mosalover Link to comment Share on other sites More sharing options...
