The marsupial bones ( Os epipubis , plural Ossa epubica ) is a paired bone for the marsupials and the monotremes is typical and can be found only in accordance with them. They are two bones protruding forward from the pubic bone of the pelvis . Since egg-laying monotones also have pouch bones, it is assumed that this could be an original mammalian feature that was reduced during the evolution of the higher mammals .

Since the pouch bones are also present in males and pouchless species, it is assumed that these bones had nothing to do with reproduction, but served the muscle attachment for the movement of the hind limbs. They are embedded in the abdominal wall bones.
