My mistake: actually they probably had hair-like protofeathers used for the sole purpose of thermoregulation.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8251798530832316093.post-41459070322855666932010-07-07T22:11:38.508-07:002010-07-07T22:11:38.508-07:00You see, I have a hypothesis, that the "quill...You see, I have a hypothesis, that the "quill knobs" are just collagen fibres like in some reptiles. Yet if ceratosaurs (based on no evidence, however) like Limusaurus and Masiakasaurus had feathers (as I see in illustrations) than chances the coelophysoids had feathers would be great (considering they were so small and would need a lot of insulation [such as Gregory Paul's illustrations of the South African Coelophysis, or "Megapnosaurus", sorry as you see I'm a "lumper"]), possibly even gliders like the microraptorines. So the probability of feathers being very early on the family tree wouldn't be surprising. In fact, they may have evolved on the Lepidosauromorpha-Archosauromorpha split in evolution.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8251798530832316093.post-70471683517735131192010-07-06T18:38:53.515-07:002010-07-06T18:38:53.515-07:00I'd look into that a bit more, it's most l...I'd look into that a bit more, it's most likely a chimera, several animals combined into one. The 'holes' are what they called knobs, as in quill knobs, but they might just be an artifact of preservation, the bones are pretty smashed up. If it is truely one animal than it might be an early bird OR a bird like ceratosaur that went nowhere evolution wise. The fact that the next bird is 75 million years after this is bothersome to say the least. Not to say it's can't happen but it seems like a long shot.<br /><br />Best,<br /><br />BrettBretthttps://www.blogger.com/profile/12168403050889835504noreply@blogger.comtag:blogger.com,1999:blog-8251798530832316093.post-25323050140064657822010-07-06T18:19:45.708-07:002010-07-06T18:19:45.708-07:00Well I've heard of Protoavis, a new archosaur?...Well I've heard of Protoavis, a new archosaur?, which lived around 250 million years ago.

There are skin impressions of infant titanosaurs that show only scales, so it might be species or group specific. I think most people play it safe and are waiting for some evidence. <br /><br />Best,<br /><br />BrettBretthttps://www.blogger.com/profile/12168403050889835504noreply@blogger.comtag:blogger.com,1999:blog-8251798530832316093.post-69250898149048348622010-06-24T15:20:12.454-07:002010-06-24T15:20:12.454-07:00Well i'm writing a book about dinosaurs on Mic...Well i'm writing a book about dinosaurs on Microsoft Word and I've seen many illustrations of early theropods covered in feathers, like Eoraptor and Liliesternus, mostly in Luis V. Rey art. Since the further you go down in history the more similar prosauropods and theropods get. And if "protheropods" were covered in feathers I'd suggest the prosauropods would of had them too.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8251798530832316093.post-53403600633932350972010-06-20T07:33:57.538-07:002010-06-20T07:33:57.538-07:00Anonymous'

I don't think most people have considered it.
