 authors put it: "_Koreanosaurus was simply placed by hand on this
 cladogramme [sic], on the base of the characters that can directly be

 (_Zephyrosaurus_-_Orodromeus_-_Oryctodromeus_) was not tested, and
 the precise affinities of _Koreanosaurus_ to other ornithischians
 remain an open question.

This means the tree in the paper is _not_ a cladogram. The term "cladogram" should only be used for the result of a cladistic analysis.

BTW, maybe the snip demon would disappear if you stopped using Yahoo!? Has anyone else had that problem?
