The teeth of Microraptor vary morphologically with position, but neither
anterior or posterior teeth resemble the known tooth of Koparion very
closely. The posterior teeth are more similar to Koparion in that they have
posterior serrations and constricted roots. Unlike Koparion, they lack
anterior serrations, have much finer posterior serrations (~25 vs. 12) and
are much more slender.

Read the inappropriately (cough, cough) copied description I posted earlier
( http://www.cmnh.org/fun/dinosaur-archive/2000Dec/msg00193.html ). The
last paragraph discusses the feathers. They are similar to those of
Liaoning birds and even have potential rachis.
