Maybe this topic should not be discussed on this
list, but the current view of Ornithodira has become so entrenched that e. g. The Dinosauricon includes pterosaurs. My
question is: What are, to date, the arguments for pterosaurs being close
relatives of dinosaurs rather than Prolacertiformes?
A website providing the evidence for
(Prolacertiformes + (Langobardisaurus + (Cosesaurus +
(Sharovipteryx + Pterosauria)))) is http://home.stlnet.com/~azero/Pterosaur_homepage.
The evidence presented there is quite compelling, but the usual hypothesis
makes some sense (e. g. one origin for ?bipedalism, ??digitigrady and
endothermy), so I'd like to know whether we really have to abandon
it.
Thanks in advance,
David
