Table 4. Measurements of the preserved bones of BP/1/4220 in millimeters.

Cervical vertebra
	Centrum length	28.5
	Anterior articular facet height	20.6
	Anterior articular facet width	20.3
	Posterior articular facet height	17.7
	Posterior articular facet width	20.1
	Maximum height of the vertebra	(38.5)
	Length along zygapophyses	(28.8)
	Length of base of neural spine	18.6
	Width of neural spine	9.4
	Width along postzygapophyses	26.4
	Width of accessory processes	13.2
rib
	Length	(109.5)

Values between brackets indicate incomplete measurements and the value given is the maximum measurable. The length along the zygapophyses is the maximum anteroposterior length between the anterior tips of the prezygapophyses and the posterior tips of the postzygapophyses. Maximum deviation of the digital caliper equals 0.02 mm but measurements were rounded to the nearest 0.1 millimeter.
