How beautiful...a dinosaur and her chicks! It really is amazing, the more we learn about dinosaurs and their evolution into birds. One of the most beautiful, awe-inspiring transformation God and nature have to offer.
"Pelecanimimus does have large paired sterna with ossified ribs and possibly uncinates, so maybe basal ornithomimosaurs were more flight-y anyway. Not only that, but the seemingly solid position of ornithomimosaurs outside Oviraptorosauria+Paraves isn't quite as definite as it seems."
Most of the vegetation in my pictures are made with custom brushes for photoshop. They are really great for making trees, bushes, grass and all kinds of plants. You should try downloading some! About the feathers, I'm not really sure if the specimens in question show definitively which areas of their bodies were covered and which were not, and so I based their feather distribution on what is expected from non-maniraptorids (naked underside and lower legs) and the naked head was just personal speculation. This could well be inaccurate, though.
I have actually tried downloading some, but it's hard to find good ones. But what I really admire here is that it doesn't look like you've used the same brush all the time, how did you do that It is something I always have trouble with...
Hmm, you could actually look at fossils of Beishanlong, as they show feather impressions too, if I'm not mistaking. And of course compsognathids were fairly closely related as well, and they are known from some well-preserved specimens with feather impressions as well.
Well, firstly I did use some different brushes from these packs. Some are shaped as ferns, others as clovers etc, that way the vegetation doesn't seem all uniform. And after setting the basic ground cover and bushes, I use the plant brushes set to multiply, screen, color dodge and color burn in different flow rates to create light and dark areas and make the plants look even more realistic and varied. I also create different layers for the plants that are closer, using bigger brushes, and those that are farther away, using smaller brushes, so you get a nice feeling of depth and distance. I hope that help
That's actually a plausible possibility.. Although really, the fact that they did have some kind of feather covering is not a surprise according to cladistics, and some people had already proposed that their second and third digits could've been joined together to support large feathers. So winged ornithomimids are not such a breakthrough, just a pleasant surprise. And thank you very much!
