what is the name of the skin between your fingers?
skin folds
the arms were short and stout with very large hands. there were no skin folds on the wrists, though a scalloped fringe of skin was present from the elbows to just below the discs on the fourth fingers. the fingers were all relatively short with large flattened discs on the tips. the discs on the second, third, and fourth fingers were about the same diameter as the tympana. small protrusions known as tubercles were present on the underside of the hands. on the first finger, the tubercles on the tipmost joints were elliptical in shape. on the second and third fingers, the tubercles below the finger joints (subarticular tubercles) were smaller than that on the fourth fingers. therewere no tubercles on the palms of the hands though elongated flat tubercles were present behind the bases of the inner fingers (the "thumbs"). numerous small and round tubercles were also present in between the joints of the fingers. the fingers were more or less fully webbed.

the wing included three clawed fingers; however, unlike in some more primitive theropods, the longest two fingers were not separate, but were bound together by the skin and other tissue forming the wing, so "anchiornis" was functionally two-fingered. these bound fingers were incorporated into a post-patagium, or flap of skin and other tissues that helped support the bases of the main wing feathers. like the toes, the skin around the bottom of the fingers was covered in tiny, rounded scales. unlike the toes, the flesh around the underside of the finger bones was twice as thick as the bones themselves and lacked distinct pads; instead, the fingers were straight and smooth without any major creases at the joints. scales and skin around the fingers is very rarely preserved in fossils of early pennaraptorans, the only notable exceptions being "anchiornis" and "caudipteryx", which had similar thick, scaly fingers associated with its wings.
