Re: Pteros might be dinos?!? Oh no ...

I was throwing a cat among the pterodactyls with this one. No, I don't
*really* think that pterosaurs are saurischians. (Although the skull of the
Late Triassic pterosaur _Raeticodactylus_ is weirdly theropod-like...)
Considering all the unexpected discoveries that have been made over the past 20
years, a saurischian ancestry for pterosaurs would not be THAT weird. After
all, we have four-winged dromaeosaurs (microraptorines); an oviraptorid as
large as a sauropod (_Gigantoraptor_); a fuzzy-coated heterodontosaur
(_Tianyulong_); an ancestral mini-tyrannosaur with _T. rex_-like proportions
(_Raptorex_); an undersized, short-necked sauropod (_Brachytrachelopan); a
long-necked stegosaur (_Miragaia_); a sauropod with a hadrosaur-like dental
battery (_Nigersaurus_); a toothless, plant-eating ceratosaur (_Limusaurus);
spiny-tailed _Psittacosaurus_; and many, many more. If any of these are
possible, why couldn't basal saurischians take to the air and become pterosaurs?
Cheers (and with apologies to _Scleromochlus_).
