FIGURE 8. Hypselospinus fittoni (Lydekker, 1889) comb. nov. Referred material. NHMUK R811, crushed sacrum (part of the holotype of Iguanodon hollingtoniensis) in ventral (A; note remains of midline keel is preserved despite crushing) and dorsal (B) views. NHMUK R811b, crushed ilium (part of the holotype of I. hollingtoniensis) in lateral (C) and medial (D) views. Note the deep, narrow preacetabular process with a low curved medial ridge, the flat iliac blade with a narrow dorsal edge and that the ventral postacetabular margin is indented and curves upward away from the ischial peduncle. Abbreviations: k – keel on ventral surface of the sacrum; mr – low, curved ridge on the medial surface of the preacetabular process; nc – floor of canal for the spinal cord; nde – narrow dorsal edge to the ilium; prp – preacetabular process; sr – fragments of the sacral ribs. Broken surfaces indicated by cross-hatching.Published as part of Norman, David B., 2010, A taxonomy of iguanodontians (Dinosauria: Ornithopoda) from the lower Wealden Group (Cretaceous: Valanginian) of southern England, pp. 47-66 in Zootaxa 2489 on page 60, DOI: 10.5281/zenodo.19557
