Ok....hmmm...where to begin.

Ok

Psittacosaurus:    Osborn 1923

P.guyangensis           Cheng 1983

P.mongoliensis          Osborn 1923
(=Psittacosaurus protoiguanodontenis =Young 1958)
(=Protoiguanodon  mongoliensis = Osborn 1923)
Note: Osborn in 1924 renamed Protoiguanodon mongoliensis to Psittacosaurus
mongoliensis

P.osborni               Young 1931
(=P.tingi = Young 1931)

P.sinensis              Young 1958*
(=P.youngi = Sereno 1990b)                

P.meileyingensis        Sereno, Chao, Cheng et Rao 1988

P.xinjangensis          Sereno et Chao 1988

 5- Psittacosaurus neimongoliensis.
 6- Psittacosaurus ordosensis.
 7- Psittacosaurus sattayaraki.

I havent heard of these...but all my refrences are, before 1990 for
Psittacosaurus.

(modified a bit from Sereno 1990a)
-------------------------------------------------------------

And could someone tell me the reference of the description of
*Psittacosaurus sinensis*


References:

Sereno 1990a, Psittacosauridae, 579-592, The Dinosauria

Sereno 1990b, New Data on parrot beaked dinosaurs (Psittacosaurus)  203-210,
Dinosaur Systematics and Approaches and Perspectives

*Young 1958, The Dinosaurian remains of Laiyang, Shantung.  
Palaeontol. Sinica (Ser.C) 16: 1-138, Chinese and English

I hopes this helps out.
