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. In PIN 156/110 the vertebrae were labeled as A or B, where A corresponds to the most anterior element in the specimen. Maximum deviation of the digital caliper equals 0.02 mm but measurements were rounded to the nearest 0.1 millimeter.
