Truly pinnate features along the entire sides of the tail are known
in the *Arechaeopteryx* complex among these taxa. In some taxa, a distal
"fan" is present, but otherwise, as in "Dave"/"Yulong" and
*Sinosauropteryx*, the tail is adorned only by a "sheath" of filaments.
Not pinnaecous ones. It is more parsimoniuous with the multitude of
with distal "fans" to propose that this is the condition more likely to
occur in other non-avian taxa.
I'm not sure about that one. Dave appears to me to have had very
well-developed vaned feathers, they are just really short, narrow, and
numerous; they seem shaggier than in Caudipteryx or Protarchaeopteryx;
however they don't look like simple hair to me.
