Re: 4 winged dino NOVA

It looks like they tried a number of positions, and came to some interesting conclusions.

As they should; it's a good way of doing things. However, this is a case where aerodynamics and anatomy have to be considered together when making final conclusions, because there are aerodynamically active positions for Microraptor that are anatomically implausible (or outright impossible).

Part of the trouble that has plagued many (most?) Microraptor reconstructions is that a great number of researchers seem dead set on making the hind limbs somehow act as "standard" wings (that is, lifting surfaces positioned to provide lift forces vertically against weight in a steady glide), which is rather unlikely.
