In reference to the post David is replying to, this is part of the
Daohugou fauna and the Daohugou Formation, mispelled earlier. For
*Scansoriopteryx*, anyway. As for the publication date, published date is
not the same as actual release, as in the case of the infamous _Canadian
Journal of Earth Sciences_ dinosaur volume 30, which was dated 1993, but
released 1994. What is the actual release date for this volume? I ask this
because I think it more a neccessary particular for this publication (ISSN
number?) to establish synonymy. If in fact the two specimens are
conspecific (the other is, of course *Epidendrosaurus*). And not that I
wouldn't want to see the name replaced, but there are considerations.
Incidentally, for an animal apparently without wings (sensu my
observations on the juvenile Epidendro) the use of the appositive noun
-_pteryx_ is interesting and ... perhaps ... politically motivated.
Otherwise, I am glad to see Gerhard Heilmann honored with a perhaps
appropriate theropod dinosaur, whatever Czerkas' view on the nature of
dromaeosaurids in systematics.

Apparently it underlies the Jehol, and is really probably quite Liassic
in nature. Where, do not know. Same problems in dating as this is a new
fauna as we see in the Jehol today.

Not only that, not a noun in sight. The etymology is scary....
I gather the specific epithet honors China and the US? "Sino-" + "USA" +

in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
