Do you need all 206 bones? Could it just be some of the bones? Could you just do like, legs and a skull? Do you need more than half?
If a creature was missing limbs in life could you raise them? (if they had a peg leg or something?)@JeremyECrawford

Animating a skeleton with the animate dead spell in D&D doesn't require all the bones.
