Other aspects of the vertebra converge upon the seventh neck vertebra of the smaller Azhdarcho most closely: the articulating sockets (cotyles) are much shallower than the neural arches, and are four times as wide as they are tall; a process on the bottom of the vertebrae, known as a hypapophysis, is present; the processes at the front of the vertebrae, the prezygapophyses, are splayed; and the vertebra has a tapered "waist" in the middle of the centrum.
