Its feather-like integument is evidence for protofeathers being basal to Ornithischia and possibly Dinosauria as a whole, rather than just to Coelurosauria, as previously suspected.

[2] In 2014, the type species Kulindadromeus zabaikalicus was named and described by Pascal Godefroit, Sofia Sinitsa, Danielle Dhouailly, Yuri Bolotsky, Alexander Sizov, Maria McNamara, Michael Benton, and Paul Spagna.

Since 2010, the area has brought forth considerable amounts of additional fossil material, including subadult and juvenile individuals.

It was found on the upper lower legs and consists of bundles of six or seven ribbon-like structures, up to two centimetres long.

Small round non-overlapping scales, less than one millimetre in cross-section, cover the hands, ankles and feet.

In the middle, to the contrary, a small spur projects forward, covering the trailing edge of the preceding scale.

[2][8] The specimens assigned to Daurosaurus and Kulindapteryx also include preserved integument on the humerus: "oval platy scales" and bristles.

[4] According to a cladistic analysis performed by the describing authors, Kulindadromeus is a basal member of the Neornithischia, placed just above Hexinlusaurus in the evolutionary tree.

[2] Heterodontosauridae Eocursor Lesothosaurus Thyreophora Stormbergia Agilisaurus Hexinlusaurus Cerapoda Kulindadromeus Godefroit et al. concluded that the filaments earlier reported in Ornithischia, with Psittacosaurus and Tianyulong, could be homologous to the "protofeathers" found in non-avian theropods.

[9] A comment on Godefroit et al. argues that the filamentous structures described at Kulindadromeus do not resemble protofeathers, rather they suggest it to be degraded collagen fibers.

[10] Pascal Godefroit and colleagues reply, “If, according to Lingham-Soliar’s hypothesis, those filaments represent collagen fibers or fiber bundles, it is surprising that they are not preserved in the numerous (more than 20) partial or whole tails of Kulindadromeus, given that the tail should have contained particularly high amounts of collagen for structural support.
