Technically, this should be 2018... My bad.

A new paper (I still believe in Kulindadromeus)

S. V. Saveliev & V. R. Alifanov (2018)
Bristle Scale As a Predecessor of Protofeather and Feather.
Paleontological Journal 52(12): 1436â1439Â
DOI: https://doi.org/10.1134/S0031030118120158

The bristle scale is a skin appendage recognized in the ornithischian dinosaurs Daurosaurus olovus and Kulindapteryx ukureica from the Kulinda locality (Transbaikalia, Russia). Morphologically, the bristle scale is a horn plate immersed in the dermis, with strands (bristles) diverging from its external edge. It is assumed that the filamentous protofeather of dinosaurs is the monobristle variant of the bristle scale and avian feather results from its tubular spatial modification. The bristle scale is considered to be intermediate between the reptilian scale and avian feather.
