 At last!  That genus can be deleted from the Dinosauria incertae sedis
 file....
 But is it a different species of Psittacosaurus (P. jingshanensis), or a
 junior synonym of another species? >>

Haven't seen Wang et al. yet (Tracy Ford should have it, since he subscribes 
to Vertebrata PalAsiatica), or if I have, I don't recall it. The Chen 
citation is:

Chen Pei-ji, 1996. "Nonmarine Jurassic Strata of China," in M. Morales, ed., 
The Continental Jurassic, Museum of Northern Arizona Bulletin 60: 395-412.

The Luanpingosaurus jingshanensis entry is on p. 408 at the bottom of col. 2. 
Luanpingosaurus jingshanensis is listed as from the Upper Jurassic Huajiying 
Formation, northern Hebei Province, China. If it is indeed a synonym of 
Psittacosaurus, or is a psittacosaurid, then it's an Upper Jurassic one and 
evidently the earliest known.
