I thought George had answered this one.  _Stokesosaurus_ of the Morrison
Formation of Utah (Cleveland-Lloyd Quarry I believe) is a possible
tyrannosaurid.  Madsen thought _Stokesosaurus_ was a tyrannosaurid back in
1974 based upon the design of the ilium.  More recently (1998) Dan Chure
tentatively referred to _Stokesosaurus_ a partial braincase from the same
locality which is strikingly tyrannosaurid-like (UUVP 2455).
