New ornithomimid?

The following abstract is for an article in tomorrow's NATURE. Anybody know 
if this is a new taxon? Chinese ornithomimids are still pretty few and far 

Palaeobiology: Herbivorous diet in an ornithomimid dinosaur


In 1997, twelve well-articulated skeletons of an ornithomimid dinosaur 
from the Upper Cretaceous Ulansuhai Formation in China were discovered. 
Each skeleton contained a preserved gastrolith mass inside the ribcage 
that was attached on the medial surface of the articulated dorsal ribs 
and gastralia. The occurrence and characteristics of gastrolith masses 
in this ornithomimid indicate that these non-avian toothless theropods 
may have had gizzards and been herbivores, like modern herbivorous birds 
that use grit to grind up plant matter.
