Kulindapteryx ukureica

Having waited what seemed like an eternity for the official unveiling of a rumoured-to-be-feathered ornithopod from Kulinda that was initially nicknamed "Kulindosaurus", and later referred to as "Kulindodromeus", that was supposed to be described by Pascal Godefroit, Alifanov and Saveliev took everyone by surprise in 2014 when they officially named a "feathered" ornithopod from Kulinda Kulindapteryx. Fossilized in volcanic ash, patches of skin show that its lower legs, feet and tail underside were scaled but the rest of it was covered with "feather-like structures" which would place the evolution of feathers closer to the base of the dinosaurian family tree, rather than in the theropod clade which is where evidence has always pointed. However, despite the "pteryx" of its official name meaning "wing", the "feathers" seem to be nothing more than bristly hairs, which is old news as such structures have already been found on other ornithischians such as Tianyulong and Psittacosaurus.

Because what should've been the official presentation of "Kulindodromeus" at SVP in 2013 was pulled at the last minute due to health issues we weren't sure if Kulindapteryx was based on the same Kulinda remains or not. Perhaps it was an entirely different species, of the same family, with similar features, from the exact same area, but our suspicious minds kept telling us that said delay opened a window of opportunity for taxonomic claim jumpers, and we feared that Godefroit had been well and truly "scooped". Allegedly, it was far worse than that.

A note from Godefroit:
"Please forget about those names (Kulindapteryx ukureica and Daurosaurus olovus). These are based on specimens that Alifanov stole in Chita and that are illegally housed in PIN in Moscow but belong, in fact, to the Institute of Natural Resources Ecology and Cryology (Chita). Moreover there is a single taxon. And it is not a hypsilophont but a basal ornithischian. This paper is a true paleontological scandal! The official paper implying the original discoverers of the specimens... and based on the legal INREC material in Chita... will be published in July in one of the highest-ranked scientific journals!"
And so it came to pass. Godefroit's paper duly arrived via "Science" and is now free to view, despite being initially hidden behind a pay-wall, but there's no mention of stolen specimens. Alifanov's paper disappeared from the interweb soon after. An admission of guilt, perhaps?
(Kulinda runner from Ukureisk)Etymology
Kulindapteryx is derived from "Kulinda" (for the area in which it was discovered) and the Latin "pteryx" (wing).
The species epithet, ukureica, is derived from "Ukureiskaya" (for the Ukureiskaya Formation).
Discovery
The remains of Kulindapteryx were discovered in the Ukureyskaya (aka Ukureiskaya) Formation (formerly the Kulinda Formation), Olovsk (Nerchinsk) Group, Kulinda Valley, 3 km west of Novoil'insk Village, Chernyshevskii District, Transbaikal region, Russia, in 2011 by a joint expedition of the Russian Academy of Sciences; the Siberian branch of the Institute of Natural Resources, Ecology and Cryology (INREC) and the Borissiak paleontological institute (PIN).
