Figure 35. Hypselospinus cf. fittoni. NHMUK R1627, R1636. Fragmentary portions of the ilium. A, NHMUK R1627, a central portion of the iliac blade of robust build collected from Brede; the dorsal margin of the blade is narrow and flattopped and there is a distinct blister-like strip of scarring just below the dorsal margin; the preacetabular blade is comparatively narrow at its base and there is no large medial ridge. B, NHMUK R1636 a central portion of the ilium collected from Shornden and illustrated by Lydekker (1890a). Slightly more complete, the dorsal margin of the blade is laterally compressed and flat-topped and there is a similar blister-like strip of scarred tissue that runs parallel to the dorsal margin; the preacetabular process is laterally compressed and concave externally and has a very reduced medial ridge. Abbreviations: ac, margin of the acetabulum; m.sc, blister-like strip of muscle scarring; pp, pubis peduncle (only partially eroded); sac, supra-acetabular crest. Scale bar = 10 cm.
