This is actually an incredible find. I'm sure with comparisons to bird feathers, paleontologists will be able to make countless inferences about dinosaur physiology. The first things on my mind are: does this tail shed light on when theropods and birds diverged in their evolution, and if so, did they go on to develop different feather traits?? Like these feathers look "normal" to the naked eye but I'm interested to learn if there is an unusual chemical makeup at play, or if the feathers have fundamentally different structures to them. forget man this is fascinating to an evolution major.
