F21731, and NHMUK PV R 1530 (the ‘Leeds’ morphotype). This list is not exhaustive. Overall, the ilium of the ‘de Blainville’ morphotype has relatively smoother posterior and dorsal margins with a proportionally longer preacetabular process, whose apex is thicker and blunt. On the contrary, the ilium of the ‘Leeds’ morphotype has a more broader-stocky appearance with irregular dorsal and posterior margins due to enlarged sacral rib attachment sites, and its preacetabular process is thin and sharp. In addition, the lateral facet of the pubic peduncle of the ‘Leeds’ morphotype is relatively more extended dorsally than in ‘de Blainville’ morphotype.

F21731, the supraacetabular crest strongly impacts the shape of the anterior margin of the ilium, whereas in NHMUK PV R 2054 and SMNS 10116 it only forms a subtle bulge. In all specimens, the supraacetabular crest extends posteriorly as far as the dorsal peak of the ischial peduncle.

, the posterior margin of the ischium is not flat but slightly bulged. The ischium of the ‘de Blainville’ morphotype displays a relatively slender shaft and proportionally longer peduncle bridge compared to the ‘Leeds’ morphotype. In the ‘Leeds’ morphotype, the anterior peduncle also seems dorsoventrally thicker.

As in other thalattosuchians, the anterior peduncle is slightly taller dorsally than the posterior one, and is also located further away from the shaft. Indeed, the junction between the anterior peduncle and the shaft of the ischium is achieved through an elongated bony structure called the peduncle bridge. Proportionally, the peduncle bridge of

) is anteroposteriorly longer and mediolaterally wider than the anterior peduncle, as in other thalattosuchians. Dorsally its articular surface is separated in two distinct areas: the facet medially oriented which is highly scarred as it was fused with the ilium, and the facet laterally oriented which is smooth and concave. The latter is also the largest and formed the ventral border of the bony acetabulum. The junction between the two areas forms a thick ridge. In dorsal view, the overall outline of the posterior peduncle resembles an ellipse but with an anteriorly flat portion, which borders the acetabular perforation posteriorly.The posterior peduncle is low-built and does not significantly stick out from the shaft of the ischium (unlike the anterior one).

The lateral and medial margins of the bone present a similar degree of concavity, with their apex situated almost at the mid-height of the bone.
