Re: Introducing Mahakala omnogovae, little dromaeosaurid of Mongolia

Is this why Tyrannosaurus rex and Albertosaurus
libratus come out as sister taxa, with Daspletosaurus
more distant?

Maybe, but that part of the tree (carnosaurs and basal coelurosaurs like tyrannosauroids) is quite undersampled anyway. Note that *Dilong* comes out two nodes closer to birds than the three tyrannosaurids, and note that neither the paper nor the supp. inf. ever mention this theoretically surprising result -- presumably because it isn't surprising given the sampling.

Of course, I don't think it matters much for deinonychosaur relationships.
