Figure 3. Schematic vertebrae showing the measurements and angles taken.

Figure 3

A, cranial view; B, dorsal view; C–D, lateral view. ML maximum length, MH maximum height, LF in dorsal view, distance between the facies articularis cranialis and caudalis, L1 in dorsal view, distance between the cranial and posterior borders of the foramen vertebrale, L4 in ventral view, maximum length of the corpus, AW cranial width, Fw1 distance between both zygapophysis cranialis, Cw caudal width. L1, L4 and Fw1 are following Guinard et al. (2009: Fig. 2), I1 development and cranial projection of facies articularis cranialis (I1 =  L4-L1/L4), I2 elongation index (I2 = L4/Fw1), the later in the same way as Guinard et al. (2009), da dorsal angle, va ventral angle, c. circa because deformation.
