More ornithischian news
OK....Here's the English-language version of the proposed new
"hypsilophodont" taxa Kulindapteryx and Daurosaurus in the Russian
journal Paleontological Journal, first published in Russian a few week
ago. (I don't have a copy of this new English-language version.) The
two "taxa" are almost certainly specimens of the neornithischian
Kulindadromeus that was named and described in detail back on July 25,
2014. Pascal Godefroit has alleged that the specimens used by Alifanov
and Saveliev were taken from the museum collection in Siberia without
authorization ("stolen") and that the names Kulindapteryx and
Daurosaurus should be ignored. For now, people seem to be following
this policy. For one thing, the entries for Kulindapteryx and
Daurosaurus were removed from the list of new taxa for Paleontology
2014 on Wikipedia when I last checked. Given the apparent scrappiness
of the type material (unlike the many specimens used to establish
Kulindadromeus) and their questionable diagnoses as "hypsilophodonts,"
there might be a case for considering Kulindapteryx and Daurosaurus to
be nomina dubia (but possible specimens Kulindadromeus).
Unfortunately, the two names were published in an established
scientific journal in Russian before Kulindadromeus was published in
Science, so they still constitute a potential taxonomic headache.
Just for the record....

Two new ornithischian dinosaurs (Hypsilophodontia, Ornithopoda) from
the Late Jurassic of Russia.
Paleontological Journal 48(4): 414-425
Two new dinosaurs, Kulindapteryx ukureica gen. et sp. nov.
(Jeholosauridae) and Daurosaurus olovus gen. et sp. nov.
(Hypsilophodontidae) from the Ukureisk Formation (?Tithonian, Upper
Jurassic) of the Kulinda locality in Transbaikalia (Russia) are
described and assigned to Ornithopoda (Ornithischia). The origin and
homology of the so-called obturator process of the ischium of
Ornithopoda and Theropoda are discussed. The families Jeholosauridae
and Hypsilophodontidae as well as Lesothosauridae are considered to
belong to the infraorder Hypsilophodontia (Ornithopoda, Ornithischia).
It is shown that hypsilophodontians had skin scales divided into
