Yutyrannus: Allosaur or Tyrannosaur?

Carnosaur
MemberCompsognathusApril 22, 20146607 Views10 RepliesRead something on Scott Hartmans Deviant art stating Yutyrannus was a species of allosaur. And, upon doing some research, have come to that conclusion as well.
Here's why i think it's an Allosaur...
The arms are long, and three fingered. A trait of early, small tyrannosaurs. Sure. However, they are not present in the Large bodied Tyrannosaurs.
Daspletosaurus, an animal of equal size (9 meters, 4 tons) and living at the approximate same time, almost shares no resemblance.
Note the two fingered, small arms
Gorgosaurus, another similarly sized animal, again shows no resemblance.
"But wait!" you must be saying to yourselves, ' it also has a covering of feathers, Do you think it isn't a Tyrannosaur because of this?"
Well, no. Small Tyrannosaurs had them as well. Such a large animal that coincidently has them as well doesn't entirely convince of Yutyrannus being one as well.
Now, let's look at the skull..
The skull reminded me of another large bodied predator..
That, is the skull of Allosaurus Fragilis.
The skulls look remarkably similar, even sharing the structure at the top of the head.
Now, let's compare Yutyrannus to the skull of Daspletosaurus
More compact, with larger spaces for powerful jaw muscles. We do not see this in Yutyrannus.
The Skull of Yutyrannus is more elongated, with smaller serrated teeth. The Characteristic'D' shape of Tyrannosaurid is not terribly noticeable in the teeth of Yutyrannus. Once again, resembling more of those of Allosaurus
Onto something a bit easier to follow...
Yutyrannosaurus shares the body plan of Allosauridae. having a relatively long neck, and an elongated tail.
Similarly sized Tyrannosaurs have a thick powerful neck, and an equally thick, powerful tail.
In conclusion...
i believe Yutyrannus is a species of Allosaur, sharing some traits with The tyrannosauridae through convergent evolution. Perhaps we are seeing an adaptation for a new prey source.
This also is the first evidence for feathers on Allosaurs, if my theory is correct. Exciting indeed.
Nature doesn't deceive us; it is we who deceive ourselves.
