Good day,
I would like to ask, if there is any comprehensive list of all known "feathered" ornithischian dinosaur specimens. That includes those with a "primitive" filamentous integument as in Psittacosaurus sp. from Yixian. Is it still just Kulindadromaeus, Tianyulong and Psittacosaurus so far? Thank you, in advance! Tom
