FIGURE 5 in A taxonomy of iguanodontians (Dinosauria: Ornithopoda) from the lower Wealden Group (Cretaceous: Valanginian) of southern England

FIGURE 5. Hypselospinus fittoni (Lydekker, 1889) comb. nov. NHMUK R1635, holotype ilium. A. Lateral view. B. Posterior view to show the inflected shelf, lateral ridge and brevis fossa. C. Medial view showing the form of the sacral rib scars. D. Dorsal view showing the transversely narrow dorsal margin of the ilium compared with that of B. dawsoni (Fig. 3B). The mediodorsal edge of the ilium shows an abscess-like excavation that may be pathological in origin. Even though the dorsal margin is eroded laterally posterior to the ischial peduncle (cross-hatched area) there is little indication of a laterally everted edge. Abbreviations: acet – acetabulum; brf – brevis fossa; lr – lateral ridge that bounds the brevis fossa; nde – narrow dorsal edge to the iliac blade; path? – probable pathological structure; prp – preacetabular process; srs – sacral rib scar on medial surface of iliac blade. Broken surfaces indicated by cross-hatching.

FIGURE 6 in A taxonomy of iguanodontians (Dinosauria: Ornithopoda) from the lower Wealden Group (Cretaceous: Valanginian) of southern England

FIGURE 6. Hypselospinus fittoni (Lydekker, 1889) comb. nov. NHMUK R1635, additional postcranial remains recovered from the same locality and horizon as the holotype ilium (Fig. 5) at Shornden. A–C. Posterior portion of sacrum (lateral, ventral and dorsal views respectively). D, E. Anterior caudal centrum, in right lateral and anterior views respectively. F. Proximal left ischium, a water-rolled and polished fragment. The ischium is of different preservation and is very probably transported to a greater extent than the other type specimens – and in any case shows no diagnostic features beyond being the proximal fragment of an ornithopod ischium. Abbreviations: cr – caudal rib; hf – haemal arch (chevron) facet; il – base of iliac peduncle; k – keel on ventral surface of sacral centrum; nc – floor of canal for spinal cord; obt – base of obturator process; pu – base of pubic peduncle; sr – fragments of the sacral ribs. Broken surfaces indicated by cross-hatching.

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.
