A reconstruction -- a quick sketch, really, about 45 mins -- of Velociraptor mongoliensis, most famousest of "raptors" despite never being depicted in a major motion picture, rendered after the reconstruction scheme of Greg Paul (rostral beaks, lips, upper teeth fitting into lower lips and thus "hidden" from view).
For various reasons, I do not think this reconstruction is accurate, either for the rostral beak or for the enveloping lips.
I have various regions. I am working on explaining why, so stay tuned. It involves reconstruction the jaws like mammals and not varanid reptiles. And even that is improbable.
Paul thought there were natual lateral crests that arose from ridges on the sides of the nasal, but these were based on his mistaken interpretation that a depression of the midline between nasals and the resultant uplift of the lateral margins meant there were ridges. This interpretation is so far from being plausible it is not being considered at reconstruction-worthy. While I could actually reconstruct it....
I dunno, I kinda find scaly dino-lips that cover the teeth a wee bit boring But then again, the sauropods in Dinosaur Revolution have lips as well Might experiment with lips for my dinos to see how it feels like
Seriously, very nice painting!
