Fossildude19 Posted December 21, 2021 Share Posted December 21, 2021 As far as I know, species cannot be determined by vertebra. There are no species distinguishing features. 1 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

pachy-pleuro-whatnot-odon Posted December 21, 2021 Share Posted December 21, 2021 Hi there, and welcome to the forum! You've definitely come the right place with your question! Unfortunately, I have to agree with Tim. Other than taking an educated guess based on size and on how dorsoventrally compressed the vertebra's articulation surfaces are (some researchers have posited that a wider articulation is indicative of plioplatecarpine mosasaurs; e.g., here and here), it really isn't possible to identify what mosasaur a vertebra came from - the more since this is not a cervical vertebra, whereas most determinations base their conclusions on the more distinct cervical vertebrae. 1 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
