Confuciusornis species

[dbensen <dbensen@gotnet.net>]

This question tyes in with my earlier post, but I feel this facet is important 
enough to give it
its own message.

Confuciusornis sanctus is a fairly well-known species.  Everybody knows what it 
looked like (fuzzy
grosbeak with long tail), but what about all these _other_ species?
C. chuonzhous
C. dui
C. sp.
C. suniae
I've read a little about C. dui (it had an upturned beak), but I know abosultly 
nothing about any
of the others.
If people out there can tell me how these species differ from the type 
(illustrations are nice),
please tell me.

Thanks
Dan
