I just ran through my mental list of tyrannosaurs and some of the ones I came up with that might fit the description of the tyrannosaur teaser are:


 * Daspletosaurus


 * Tarbosaurus


 * Dilong/Guanlong


 * Dryptosaurus


 * Teratophoneus

But that's just a speculation on what I think. It could be Yutyrannus or another tyrannosaur.
