Yes. Basically, the eggs long identified as from _Orodromeus_ in fact belong
to _Troodon_ (see Horner & Weishampel 1996. Nature 383: 103). From the
Varricchio et al. paper:
"Additionally, the tentative assignment of Two Medicine ornithoid-ratite
egs with a dispersituberculate surface to ?_Troodon_ (...) is incorrect.
These eggs remain unassignable to a specific dinosaur taxon."
Off the top of my head, I would speculate those eggs might be
_Chirostenotes_ or _Ricardoestesia_, among named dinosaurs.
