Since _Ornitholestes_ seems to occupy a phylogenetic position close to
that of compsognathids, including _Sinosauropteryx prima_, feathery
integument seems most likely. _S. prima_ is the best model to use for
now. (And perhaps _Dilong paradoxus_ is the second-best model.)

So far, remiges and rectrices seem to be limited to _Maniraptora_
sensu Sereno, though.
