This condition differs from that noticed in most theropods (e.g., Avimimus, Sinraptor, Tyrannosaurus; Currie Zhao, 1993; Vickers-Rich, Chiappe Kurzanov, 2002; Brochu, 2003), such as Velociraptor (Fig. 176 in Turner, Makovicky Norell, 2012), with only Adasaurus, Anchiornis, Deinonychus and Velociraptor scored as bearing that function. Nonetheless, a prominent ischial tuberosity is also present in avialans,Cau et al. (2015), PeerJ, DOI 10.7717/peerj.12/Figure three Comparison amongst the pelvis of Balaur as well as other paravians.

It is also a common feature in pygostylian birds (e.g., Confuciusornis, Patagopteryx, Sapeornis; Chiappe et al., 1999; Hutchinson, 2001; Chiappe, 2002; Chiappe Walker, 2002; Zhou Zhang, 2003).Broad pelvic canal with laterally convex pubes and abrupt distal narrowing of interpubic distanceBrusatte et al. (2013) noted as an autapomorphy of Balaur an interpubic distance that may be proportionally greater than that present in other dromaeosaurids (e.g., Velociraptor; Norell Makovicky, 1997; Norell Makovicky, 1999). The gap between the laterally bowed pubes of Balaur only starts to narrow abruptly within the distalmost third from the bone (Fig. 3B and Fig. S2B; Brusatte et al., 2013, Fig. 56). This condition differs from that noticed in most theropods (e.g., Avimimus, Sinraptor, Tyrannosaurus; Currie Zhao, 1993; Vickers-Rich, Chiappe Kurzanov, 2002; Brochu, 2003), including Velociraptor (Fig. 3D and Fig. S2C; Norell Makovicky, 1999; Brusatte et al., 2013), Bambiraptor (Burnham, 2004) and Archaeopteryx (Norell Makovicky, 1999, Fig. 25), where the narrowing is much more gradual more than the length from the pubes and the pubis will not be bowed laterally in anteroposterior view. Brusatte et al. (2013) noted that the situation in Balaur is somewhat comparable towards the situation in therizinosaurids (Zanno, 2010). The combination of a reasonably broad pelvic canal, bounded by laterally convex pubes and with an abrupt distal narrowing in the interpubic distance, can also be seen in pygostylian birds (e.g., Concornis, Dapingfangornis, Piscivoravis, Sapeornis, Yanornis; Sanz, Chiappe Buscalioni, 1995; Zhou Zhang, 2003; Li et al., 2006; Zhou, Zhou O'Connor, 2014; Zheng et al., 2014; see Fig. 3C and Fig.
