I would think that if you could make some type of arguement about it`s
degree of endothermy, it`s size,... and could find some evidence of the
climate in which it existed, you could make a pretty good prediction of
whether or not it may have had integumentary fibers. It`s possible link to
pterosaurs and active flight, do suggest an endothermic metabolism (IMHO).
