I'm not clear what you mean here. When you say "leaping after prey" do you
mean leaping off the ground in pursuit of terrestrial prey? If so, why is
this better than just simply running after the prey (i.e., the

That's exciting news. I wonder, though, if the folded-up feathers reflect
the condition in life, or are taphonomic artefacts (as suggested for the

I totally agree with the last point. But the elaborate aerodynamic plumage
appears to me to be overspecialized for simply running and jumping on prey.
However, the _Microraptor_ plumage does appear appropriate for assailing
terrestrial prey from above, when aerial control is essential for the
It _would_ be nice to get full fluff, complete with tail fans and wings on
the JP 'raptors.
What would _Velociraptor_ use them for...?
