Embryos don't have tails. Suggest you study conception to birth development a little. The bone structure develops long before the fat is filled out. Thus the bones at the end of the spine, which will soon be surrounded by rear end fat, begin as an exposed area of bone. This, however, is not a tail. Nor was it ever a tail.

Human Tail
The human tails refers to a extremely rare and benign condition where a child is born with a persistent vestigial tail-like cutaneous structure in the lumbosacrococcygeal region. Pathologically, two types of human tails have been recognized: the true and pseudo human tail. The true human tail arises from the most distal remnant of the embryonic tail lacking bone, cartilage, notochord and spinal cord. Contains a central core of mature fatty tissue divided into small lobules by thin fibrous septa with small blood vessels and nerve fibers scattered. The true tail arises by retention of structures found normally in fetal development. It may be as long as 13 cm, can move and contract, and occurs twice as often in males as in females. The pseudotail is a short, stump-like structure. Spina bifida (dysraphism) is the most frequent coexisting anomaly in both anatomical variants (50%). Other associated lesions include tethered cord syndrome, lipomas, teratomas and gliomas. Investigation of children born with human tail appendages should include a thorough neurological examination, plain x-ray films of the lumbo-sacral region and contrast MRI imaging looking for dysraphism and associated lesions. Management consist of surgical excision of the vestigial tail and repair of the dysraphism. Long-term follow-up for possible sequelae after surgery, especially in cases with spinal dysraphism, is necessary.
