In sum, the fossils of Daohugou could be from mid-late Valanginian to

The Daohugou Bed has also yielded _Chilantaisaurus tashuikoensis_ and _"C"_.
maortuensis_ - though apparently the two species come from different levels.
Google finds the pdf.
I found a site with the pdf, but I would have to cough up $9 for access.
