). But on the other hand, the ischial peduncle of NHMUK PV R 3898 is drastically thinner mediolaterally whereas this is not seen in the other specimens. Indeed, in NHMUK PV R 3701 and NHMUK PV R 2076, the maximal mediolateral thickness reached by the pubic peduncle is either similar (NHMUK PV R 2076) or slightly greater (NHMUK PV R 3701) than that of the ischial peduncle. Compared to NHMUK PV R 2076 and NHMUK PV R 3701, PETMG R178 and NHMUK PV R 3898 are significantly larger and it is possible that it accounts for the difference in the size and shape of the ischial peduncle (

). In NHMUK PV R 2076 and NHMUK PV R 3701, the outline of the pubic peduncle ventrally is crescent-shaped (i.e. smoothly curved lateral and medial margins) with its tips begin rounded rather than sharp. In NHMUK PV R 3898 the ventral outline of the pubic peduncle is different as the anterior and medial side form a right-angled corner. The facet of the pubic peduncle on the lateral surface of the ilium displays a greater dorsal extension than the ischial peduncle in PETMG R178 (partially altered anteriorly), NHMUK PV R 2076 and NHMUK PV R 3898; the ilium of NHMUK PV R 3701 is too strongly altered to observe the exact shape of the pubic peduncle laterally.

PETMG R178, NHMUK PV R 2076, NHMUK PV R 3898, and NHMUK PV R 3701 all share the same shape for each of their attachment sites, but their relative size varies across the specimens. Each attachment site is quadrangular in shape and appears like the mirrored version of the other. Indeed, both their dorsal and ventral borders converge towards the centre of the ilium, and their exterior side – either anterior or posterior – is parallel but drastically larger than the shared central margin. The linearity of the shared central delimitation contrasts with the curved one of

This effect is partly provoked by the relative inclination of the sacral rib attachment sites, which are dorsally sinking towards the ilium. Comparatively, in

In addition, the peduncle bridge is curved medially like

is mediolaterally large as it accounts for about one-fifth of the total proximodistal height of the pubis. Proximally, the outline of the peduncle of NHMUK PV R 2076 andNHMUK PV R 2865 approximates that of a droplet, with the sharp corner pointing laterally. In comparison, NHMUK PV R 3701 shows a more elliptical outline for its peduncle. The medial and lateral margins of the pubis underneath the peduncle are both concave with a similar degree of intensity. Also, the apex of each concavity is set at the same distance from the peduncle, all of which result in a relatively thin shaft mediolaterally. Indeed, the mediolateral constriction of the shaft reaches about 42% of the mediolateral width of the pubic peduncle. In addition, the shaft of
