TABLE 9. — List of measurements in mm of crocodyliformes pubes. When measurements are missing on the first bone, it takes measurements from the next one. SMNS 81608 has been reconstructed. Abbreviations: H, total proximodistal height; Wh, mediolateral width at mid length; Ldia, length of diaphysis; Lbl, freehand length of distal blade up to diaphysis; Dbl, distance between both medial and lateral extremities of distal blade; Wprox, anteroposterior width of proximal peduncle; Lprox, mediolateral length of proximal peduncle; Shaft, proximodistal length of shaft; Neck, proximodistal length of neck; C, anteroposterior width of constriction; Arch.l, anterior arch length from peduncle to pubic diaphysis; Arch.h, maximal depth between base arch and bone margin; Arch.d, distance between proximal base of arch and position of max depth along the arch.
