U+1312F Egyptian Hieroglyph F044

The Wikipedia has the following information about this codepoint:

The ancient Egyptian Bone-with-meat hieroglyph (Gardiner F44) represented: "ancestry, inherit", and phonetic isw, iw' (inherit, etc.); a determinative for the femur, (iw'); and swt, for the tibia.

The Old Kingdom usage on slab steles, from the middle of the 3rd millennium BC, shows the proto-type form of the hieroglyph as a 'cut of meat', much like the spare ribs or beef ribs of the present era. The slab stela shows the bone as a multiple of two curved bones, much like the spare rib.

An example of a wall relief scene from Edfu at the Temple of Edfu shows a cartouche with the joint of meat hieroglyph. Another less common hieroglyph pictured within the cartouche is the vertical standing mummy hieroglyph.
