Summary of ossification sequences in the first 11 mammalian vertebral elements

For each taxon, circles indicate centra, and squares indicate left and right neural arches.

Colours represent the order of ossification.

Hox expression boundaries in the mouse^[1] and vertebral segment identity are shown at right. Note the conserved timing of V7 centrum ossification across mammals, including sloths, and the overlap in Hox5-6 expression in the V6–V9 region of the sloth neck.

• bradypus - three-toed sloths are the only members of this genus
• dasypus - armadillo genus in the Dasypodidae family
