Re: Combined answer: Feathered/scaly theropods: trying to make the point.



    I think that _Santanaraptor_ might have had some sort of disease before
he died, or he was changing his feathers, or even he might have had some
areas of the body without feathers, if it was so (on the skin impressions
subject). If instead of feathers he has had scales, I think that there are
not many causes of scale lost in lizards or snakes, so I don't know what to
say (I'm don't have knowledge on reptiles skin diseases). If instead of
feathers or scales he has had only "lheathery" skin or something over its
skin, that may be the first time in dinosaur history that these kind of
impressions are found (someone correct me if I'm wrong).
    The only thing I'm pretty sure of, it's that _Santanaraptor_ has muscles
and capillaries and other cellular-level structures very well preserved, as
I've seen in pictures.
