Reply to comment by herbw in TIL - Modern mammals are unique among vertebrates for possessing three tiny bones in the middle ear, which are unique in that they are separated from the jaw, critical because it allows the separation of hearing and chewing, and also allows hearing of high-pitched noises. by byronhadleigh

You may want to re-read the article OP posted then. It talks exclusively about the middle ear and the middle ear bones (which it mentions by name as well). The semi-circular canals are in a different part of the ear and do not appear to have been the bones that used to be attached to the jaw. The pictures are jaw bones.
