Star Wars Episode 2: Attack of the Clones - Very Strange Arm
In the bar scene, where Anakin and Obi-Wan are chasing Zam Wesell (The bounty hunter), and OB cuts off her arm, if you look very carefully while it's falling, you see that it's cut off at the elbow, and then they show her again, and it's cut off at the shoulder, and then they show her again, and then it shows her dying from the saberdart, and it's either not cut off at all, or at the elbow.
since this was a shapeshifter this is totally possible, and what if she had limbs with two elbows, this could explain why she had a limb on the ground which looked like it was severed at the shoulder, and still had an upperarm on her body
