Would a mere skeleton be described as a 'tall dark figure like a shadow'? Wouldn't you think Frodo would have described bare bones, if that's what he'd seen?

It seems the 'What are Barrow-wights?' question once again rears its ugly head.
The wights must have had a corporeal form.

Round the corner a long arm was groping, walking on its fingers towards Sam, who was lying nearest....

That arm was not described as 'skeletal' either.
I've heard arguments that what Frodo saw in the barrow were the animated remains of who was buried there, and the same spell that preserved the weapons and treasure it contained also kept the remains from corruption. It is unlikely the arm was merely dead flesh, however.

Some say that the mound in which the Ring-bearer was imprisoned had been the grave of the last prince of Cardolan, who fell in the war of 1409.

In the days of Argeleb II....an end came of the Dúnedain of Cardolan, and evil spirits out of Angmar and Rhudaur entered into the deserted mound and welt there.

Argeleb II's reign presumably began upon the death of his father, Araphor in 1589, and Argeleb died in 1670. Therefore, those remains had to have been in the barrow at least 180 years, plenty of time for advanced decomposition before the Wight arrived, so the arm Frodo saw could not have been part of the corpse.
