The holotype specimen of *Scansoriopteryx* shows a tail with tubercular, roughly rhomboid scales on a patch of the tail, preserved as impressions, leading some (including myself) to hypothesize that the tail lacked feathery integument at least on one portion (like scaly-tailed squirrels) or all of it (like in muroid rodents).
In addition, "Dave" sports scutellate scales on the pes, similar to those few non-dinosaurian, non-pterosaurian reptiles recovered from the Yixian.
