Four-toed theropods

["Tim Williams" <T.Williams@cclru.randwick.unsw.edu.au>]

The August issue of _Cretaceous Research_ has an article on four-toed 
theropod footprints from the Late Cretaceous of Wyoming (Harebell 
Formation, Maastrichtian, NW Wyoming).  The authors are convinced that 
the footprints belong to a theropod (digital proportions, sharp 
claws), but throw their arms in the air on the question of _what 
kind_ of theropod their owners are.

I haven't read the article yet, just the abstract.  Is it possible 
that these four-toed theropods are segnosaurs (therizinosauroids to 
some) - the first evidence of such from North America.
