 Formation of Liaoning, China.  It has been mentioned in two news articles
 this year.
 "Grusimimus" is a basal tetradactyl ornithomimosaur known from forelimbs,
 pelvis and hindlimbs found in the Early Cretaceous of Mongolia.  Barsbold
 announced it in a 1996 press conference with Gallimimus "mongoliensis" and
 said it was closely related to Harpymimus. >>

Would like to know whether these names have actually seen >print< (and not 
just electronic/Internet chatter). News articles (need authors and dates) 
will do fine.
