Newest and first painting of 2012. Microraptor swoops in on Confuciusornis. 10 points if you can tell what animal I used (loosely) as a color reference for the little guy  |

The confusciornis looks like a Ramphastos sulfuratus. They are more commonly known as keel-billed toucans.

The Microraptor's leg feathers should face sideways.

The Microraptor's leg feathers should face sideways. I didn't forget that. Check out the feet. They are angled inward and therefore the feathers are as well thus making them face downward for this pose. Yes the confuciusornis is loosely based off of keel-billed or swainson's toucans. Thanks everybody. |

Ah, didn't catch that. Nice painting. I like the content expression on the Confuciusornis' face.

Leg wings seem ok, but deinonychosaurs like most non avian maniraptors can´t raise their wings over the shoulder level. Dont remember if this could be different in Microraptorines, but I don´t think so. Maybe the Micro body should be a bit more compact and thickly feathered too, looks way too thin. Nice picture otherwise, specially the Confuciusornis.

Nice picture otherwise, specially the Confuciusornis. Some dromaeosaurs could bring their arms up past the shoulders. Unenlagia is probably the most noteworthy for showing evidence of this. I have seen illustrations by Greg Paul and Luis Rey showcasing a way more extreme pose than what I painted here in feathered non-avian dinosaurs as well. The feathering is more personal preference I think. I have seen plenty of slender credible illustrations of microraptor as well. I decided to make the confuciusornis more heavily feathered and plump looking and microraptor more streamlined. Thanks guys for the input I had a lot of fun doing this one. I'm going to try to do paintings on a more regular basis soon. |

The flapping theory with Unenlagia seems to be a bit outdated actually. Quoting wiki:
"The shoulder girdle of Unenlagia was originally interpreted as if it was adapted for flapping, with a flat scapula positioned on top of the ribcage, making the shoulder joint point more laterally. However, in 2002 Kenneth Carpenter pointed out that this would imply that the shoulder-blade was dorsoventrally flattened instead of laterally as with other theropods and that it thus were more likely the scapula was located on the side of the ribcage. This conformed to a later hypothesis by Philip Senter that non-avian theropods like Unenlagia were unable to lift their forelimbs above their back, as even would still have been the case for the basalmost bird Archaeopteryx"
Not sure if there´s any other more recent paper or study refuting this. But still it wouldn´t be the norm among deinonychosaurs, let alone dromies. We don´t have any evidence of non avian theropod forelimbs able to raise over the back; looks like this only evolved within neornithes. Not even enantiornithes, which are technically birds could flap their wings like modern birds...

Hm I'll look into it and ask around. Either way I don't think the arms on my illustration are that extreme to the point that its a glaring imperfection. EDIT: Okay so I asked around and did some digging and was directed to this paper. Basically it shows that non-avian theropods could not flap like modern birds do but within that HUGE span of different animals there was a lot of variation in just how far they could raise their arms. In the case of microraptor (looking at the table on pg 309) it was a little above the back at the most. That being said I think my drawing can be considered okay  app.pan.pl/archive/published/app51/app51-305.pdf |
