Theri Fan Posted April 17, 2023 Share Posted April 17, 2023 Hi everyone, I'm very new to fossils and fossil collect and I just bought some off a private seller who got them from the somerset museum. I believe these a vertebrae and was wondering if anyone could tell me what they are from, or any general knowledge. Thanks Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted April 17, 2023 Share Posted April 17, 2023 Absolutely no question about it: these are ichthyosaur vertebrae. Unfortunately, apart from being able to tell you that these are likely from the pectoral region, closer to the neck, based on the positioning of the parapophyses (rib attachment sites) and slight downward pentagonal shape, such parvipelvian (= derived, thunniform ichthyosaurs) vertebrae are rather undiagnostic as to genus or species. It's rather locality that's informative in these cases. Preservation, however, suggests Abingdon as likely find location, which would make them Brachypterygius extremus, an Upper Jurassic/Kimmeridge Clay species... 2 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...
