Figure 5. Iguanodon (= Hypselospinus) fittoni. Holotype. NHMUK R1635. The ilium as illustrated in Lydekker (1890a: fig. 1C). A, lateral; B, ventral portion of the postacetabular process. The original illustration indicates the existence of a separate anterior portion of the preacetabular process; this latter part has not been found in the collections of the NHMUK since it was first looked for in 1974. C, teeth with the same registered number as the holotype and, although not mentioned before, presumably associated: 1. The stump of a heavily worn dentary tooth; 2, 3. Worn maxillary crowns in labial view. Abbreviations: brf, brevis fossa; ch, channel for replacement crown; p, primary ridge; prp, preacetabular process; r, subsidiary ridges. Scale bar = 10 mm.
