Nanotyrannus without Feathers

THIS dinosaur has been the source of much debate. The key issue is: Was this Theropod dinosaur a separate species of Tyrannosaur, or was it a juvenile T. rex?  Recently, evaluations have supported the idea that Nanotyrannus is a separate species of dinosaur.  It has some unique traits that would not have changed to be like a T. rex. 

Nanotyrannus with Feathers

Nanotyrranus was a smaller Tyrannosaur about 18-20 feet long or around 5 meters long. It weighed about 1500 lbs. or a mass of 680 kg.  It was around only 1/10 the weight of a full-grown adult T. rex. It has been discovered that it lived at the same time as Tyrannosaurus rex. Nanotyrannus was smaller and much faster. It had teeth made for slicing, not breaking bones. That is one of several differences that show that Nanotyrannus was a separate contemporary species of Tyrannosar, but NOT a T. rex.  

There is a possibility that Nanotyrannus had feathers, since its Tyrannosaur cousin Yutyrannus had feathers. But maybe Nanotyrannus only had feathers as a juvenile, in order to keep warm. But it lost its feathers when it fully matured.  So far, we do not know conclusively. 

I have a challenge for you:  What differences do you see in the second drawing?  It is similar, but many things have been added to the drawing.  Obviously, the second drawing has a feathered dinosaur.  What else is different or added?
