Early June, two years ago, I found this ichthyopterygian vertebra in a small nodule out of the northern French Middle Triassic, from the Upper Muschelkalk. Almost two years to the day later a friend of mine helped me complete its preparation this month. When done, one of the first things that struck me were the elongate, and slightly tilted rib attachment sites. As far as I know, such rib attachment sites do not occur in any parvipelvian ichthyosaur species, which, instead, have round, button-like, attachment sites, especially on dorsal vertebrae as my find is. Now I realise that ichthyosaur vertebrae typically hold very little diagnostic value, but I was wondering whether the peculiar rib attachments might be indicative of a super-family, family or even genus, so that I can label the vertebra more informatively than "indet. basal ichthyopterygia". Nothing is known of the species at the sites where I found this, though, based on size alone, Cymbospondylus sp. seems like a good candidate. Any other ideas? @Pemphix @sander @paulgdls @Welsh Wizard @Crazyhen Dimensions of the specimen: 41mm (diameter) x 21 (depth)
