the coccyx is formed from muscle supporting proximal caudal
vertebrae, not part of the sacrum. One may note that, except in
anurans, no vertebrates have a sacrum comprised primarily of the
caudals. The sacrum is typically composed of dorsals first, then
caudals, and the synsacrum becomes comprised of dorsals, with a
few caudals to support femoral adductor and extensor
musculature. Mammals support a coccyx, such as in bovids,
whereas the first several caudals are not integrated as a
caudo-sacrum [urostyle?] but are united proximal to the free
caudals, which do not support hip muscles.
