Figure 30. Plot of the measured distance from the cranial end of the
cervical vertebral centrum (measured from the caudal end of the cranial ball, or
condyle) to the diapophysis as a function of total centrum length (measured from
the caudal end of the cranial ball to halfway up the caudal articular surface)
for the cervical series 3-8. Axes have been transformed to natural logarithmic
space. The regression line [Ln y = 1.925(Ln x) – 5.5126; R2 = 0.9803]
represents the curve that best fits the data for Brachiosaurus brancai.
