It is the lower Cretaceous age of the strata that makes me skeptical 
that the eggs are those of Tyrannosaurus bataar.  The age is some 25+ my 
older than known T. bataar skeletons.  On the other hand, I have also 
seen an Upper Cretaceous age assigned to the same formation.  At 
present, I do not know the proper age of the formation, nor the real 
identity of the egg layer
