Raptorex kriegsteini

Raptorex kriegsteini is a Jehol despot with a sordid past. It looks so much like a baby Tarbosaurus, I and others doubted whether its referral to the Yixian Formation, and therefore to a distinct species, was accurate. It's now looking more likely that this little guy is a juvenile tyrannosaurid of some as-yet undetermined species (or new species) from the LK of Mongolia.

I gave this sparser feathers than Dilong and Yutyrannus. I figure if Dilong is indeed a basal deinodontoid, I can show the transition from more feathers to less in the big guys.
