What about the following dubious taxa: Actiosaurus, Pachygonosaurus and all the species of Pessosaurus. Where do you suggest to put them? Rnnsh ( talk) 18:39, 12 January 2013 (UTC) reply

Pessosaurus has been classified as a shastasaurid before, so I'd put it under Shastasauridae with a question mark. Most species claimed to be shastasaurids are probably just basal merriamosaurs, but as far as I know Pessosaurus hasn't been included in any phylogenetic analyses. The others could be put under a new row called "incertae sedis", but then we need to know whether or not each one is a parvipelvian. Pachygonosaurus comes from the Triassic according to Shikama et al. (1978) so it's probably non-parvipelvian. Do you know anything about Actiosaurus?

Maybe we should call the raw "nomina dubia" or somthing and put it "at the base" of Ichthyosauria - Pessosaurus was not assigned to any particular group of ichthyosaurs since Maisch & Matzke (2000) (both "schemes" support the view that it is dubious...). And about Actiosaurus - is it even an ichthyosaur? There is a nice post on him at the Theropod Database Blog since it was originally thought to be a theropod...

Sounds good. As for Actiosaurus, if it's probably not an ichthyosaur at all, it's probably not worth putting on this template. Smokeybjb ( talk) 19:57, 12 January 2013 (UTC) reply
