. Each attachment site is located directly medially to a peduncle: the first attachment site is placed medially to the pubic peduncle, whereas the second one is located medially to the ischial peduncle. Within each attachment site, a thin ridge emanating from the dorsal margin of the imprint partially subdivides it into two subareas, giving the impression of four distinct parabolic imprints. Yet, the ridge slowly fades away ventrally, so that each sub-areas are united along the ventral margin of the ilium. There is a difference in the sacral rib attachment sites from

|

23368 shows a large rugged area posteriorly to the second attachment site, whereas this area is much more restricted in YPM VP.000753. This area is shallower than the actual attachment sites, probably because it was merely guiding the posterior extension of the second sacral rib. Indeed, its shallowness presumably prevents it from being used as an anchor point for the sacral rib, so that it probably rather served as an additional stabilizing or locking feature. There is a similar area observed on the ilium of other dyrosaurids that presumably filled the same purpose.

The posterior peduncle is smaller than the anterior peduncle. In dorsal view, the overall outline of the posterior peduncle appears like a thicker version of the wedge-shaped anterior peduncle, with the concavity oriented anteriorly in this case. The articular surface of the posterior peduncle is slightly truncated leading to a strictly dorsal area and a more anterolateral one. The strictly dorsal area was connected to the ventral surface of the ischial peduncle of the ilium (both where interlocked), whereas the anterolateral one follows on from the shape of the ischial peduncle of the ilium. The neck of the posterior peduncle is concave laterally, medially, and anteriorly where it forms the posterior wall of the acetabular perforation. The ischial acetabular perforation is almost as large as its counterpart on the ilium (

, etc.). Posteriorly, the neck of the posterior peduncle is rather convex, but the concavity is inverted for the remaining of the posterior margin of the ischium (i.e. including the shaft and distal blade). Indeed, the overall anterior and posterior margins of the ischium underneath the peduncles are concave. Ventrally to the peduncles, two consecutive areas can be observed: first is a bottleneck portion corresponding to the shaft or neck of the ischium; and second is a flared out area called the distal blade. The transition between the two parts is set at the start of the distal enlargement and torsion of the neck. Indeed, the distal blade of the ischium gradually shifts from the orientation of the shaft to display a more medial orientation distally, similar to extant crocodylians (i.e.

The shaft itself stretches from the peduncle proximally up until the distal widening, which marks the beginning of the pubic apron. The shaft is topped with a slightly concave articular facet called the pubic peduncle. The pubic peduncle displays a sloping articular surface in anteroposterior view, which may actually reflect the curved or wedged anterior surface of the anterior peduncle of the ischium.

. The junction between the shaft and the pubic plate is identifiable thanks to both the anteroposterior flattening and dorsal bending of the bone (visible in lateral and medial views). There, the pubis starts to gradually widen lateromedially in the distal direction. At the junction between the shaft and the pubic plate, the lateral and medial margins of the shaft are locally parallel then rapidly flare out proximally and distally, creating concave lateral and medial margins. Conversely, the anterodorsal and posteroventral surfaces of the pubis (in lateral view starting from the junction) only dimly flare out proximally, and even become slightly finer distally. The distal portion of the pubis – the pubic plate or apron – comprises five distinct margins: the two lateral ones, the two medial ones, and finally the distal one. The concave medial margin is shorter than the lateral one as it abruptly transitions (through an obtuse bend) into the straight margin constituting the pubic symphysis. In YPM VP.000753 (
