The differences in the premaxilla and its teeth got me thinking about this subject again.<br /><br />www.reptileevolution.com/darwinopterus.htm<br /><br />David PetersD.P.https://www.blogger.com/profile/13009843520057633239noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-21263361103234199332009-10-21T08:47:10.690-07:002009-10-21T08:47:10.690-07:00Superficially the skulls of Germanodactylus and Da...Superficially the skulls of Germanodactylus and Darwinopterus do resemble each other, but I did noticed that the shape of the rostrum is different: in Germanodactylus it seems quite more robust and straight from the end of the nasoanteorbital frenestra onwards, while in Darwinopterus it sort of resembles the condition in Quetzalcotalus, with a curve more or less towards the end of the nasoanteorbital frenestra and thus having a less deep rostrum. The jaw of Darwinopterus also seems to remain more constant in shape, whereas Germanodactylus' is thinner at the tip.<br /><br />I assume this stresses their different lifestyles. Darwinopterus was hunt vertebrates, whereas Germanodactylus does seem to be going on the same direction as DsungaripterusCarlos Miguel Albuquerquehttps://www.blogger.com/profile/15403916224472065107noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-67405051038094433882009-10-21T06:57:26.737-07:002009-10-21T06:57:26.737-07:00You know that's really interesting. I wonder i...You know that's really interesting. I wonder if when other basal pterodactyloids of either various groups or the clade as a whole turn up they might have the same kind of skull. Germanodactylus has been floating around the bottom of pterodactyloid taxonomy, with some authors considering it closer to Pterodactylus and such. The most recent study by Unwin suggests it was a basal dsungaripteroid, which if true would either mean convergent evolution (perhaps meaning that aerial predatory, if it is the kind of lifestyle that Darwinopterus pursued, evolved more than once in pterosaurs) or else most basal pterodactyloids had a similar skull.<br /><br />I find myself laughing at Czerkas assessment too, I went to his museum in southeastern Utah over the summer and it was horrid! His museum was stating BAND rhetoric everywhere, going so far as to say that maniraptorans and pterosaurs were sister groups, and that the clade of maniraptorans+pterosaurs was the sister group to dinosauria as a whole. Wait, what? (And yes, his Pterorhyncus was on display).Anonymousnoreply@blogger.com
