Figure 7 in Reassessment of the Lower Cretaceous (Barremian) pliosauroid Leptocleidus superstes Andrews, 1922 and other plesiosaur remains from the nonmarine Wealden succession of southern England
Figure 7. Phylogeny of pliosauroids using the character matrix of Smith & Dyke (2008) and incorporating rescored data for some Leptocleidus-like taxa (see Appendix). Strict consensus maximum parsimony trees with multistate characters ordered (A, B) vs. unordered (C, D); and excluding taxa incorporating> 65/55% missing data (B, D: see text for details). Bayesian tree with multistate characters unordered (E) and then excluding taxa incorporating> 65/55% missing data (F, ordered vs. G, unordered). Boxed numbers represent character states (A–D)/posterior probabilities (E–G) at selected nodes (•); *plesiomorphic state. Bootstrap/Bremer support values for major clades are given in the text.
Figure 47. Hypselospinus fittoni. A in On the history, osteology, and systematic position of the Wealden (Hastings group) dinosaur Hypselospinus fittoni (Iguanodontia: Styracosterna)
Figure 47. Hypselospinus fittoni. A preliminary reconstruction of the skeleton based upon the type and referred material described in this article. NB: forelimb relative to hindlimb length, and proportions, are currently unknown. Scale bar = 1 m.
Figure 12 in On the history, osteology, and systematic position of the Wealden (Hastings group) dinosaur Hypselospinus fittoni (Iguanodontia: Styracosterna)
Figure 12. Hypselospinus cf. fittoni (Iguanodon hollingtoniensis holotype). NHMUK R1148. A, B, dorsal centra as preserved in lateral view. A1, centrum A illustrated and pseudo-articulated with a neural arch; A2, centrum and neural arch in ventral view; B1, similar pseudo-articulation and B2, ventral view of the same. Hatching indicates broken surfaces. Abbreviations: dia, diapophyseal facet; k, keel; par, parapophysis; poz, postzygapophysis; prz, prezygapophysis. Scale bars = 10 cm.
Figure 11 in On the history, osteology, and systematic position of the Wealden (Hastings group) dinosaur Hypselospinus fittoni (Iguanodontia: Styracosterna)
Figure 11. Hypselospinus cf. fittoni (holotype: Iguanodon hollingtoniensis). NHMUK R1148. A−D, left metatarsal (mt) III in dorsal, ventral, proximal, and distal views, respectively; E−H, left mt II (R1629) in dorsal, ventral, proximal, and distal views, respectively; I−N, proximal pedal phalanx (?I−IV) in lateral, medial, dorsal, ventral, distal, and proximal views, respectively. Abbreviations: lig, scarred surfaces for ligament attachment; sc, scarred surface; tab, flap-like tab on the dorsolateral margin of mt II; tab.sc, corresponding scarred and indented surface on the medial edge of the shaft of mt III for the attachment of the tab on mt II. Shading: even tone, proximal metatarsal surface; hatching, broken surfaces. Scale bar = 10 cm.
Figure 9 in On the history, osteology, and systematic position of the Wealden (Hastings group) dinosaur Hypselospinus fittoni (Iguanodontia: Styracosterna)

Figure 36. Hypselospinus cf. fittoni. NHMUK R1831. Dentary right with teeth preserved in situ. A, medial; B, lateral; C, dorsal views. Abbreviations: am, alveolar margin; br, badly broken portion of the dentary; cp, coronoid process; ds, dentary symphysis; m, matrix; mgr, Meckelian groove; pr, anterior lateral process of the dentary; sf, sutural facet; sl, 'slot-and-lip' portion of the dentary symphysis; tf, tooth fragments in alveolar bone; vc, vascular channel.

Figure 39 in On the history, osteology, and systematic position of the Wealden (Hastings group) dinosaur Hypselospinus fittoni (Iguanodontia: Styracosterna)
Figure 39. Hypselospinus cf. fittoni. NHMUK R1831 (R1832, R1833), R33. Digits II−IV of the manus reconstructed. A, metacarpals II−IV (right) reconstructed in articulation (dorsal view). B, NHMUK R33. Metacarpal III (uncrushed, right) showing natural width for comparison with: C, NHMUK R1831, which is transversely compressed. D, digit II (left, inverted), ungual phalanx somewhat distorted; E, digit III (left, inverted), distal end (only) of metacarpal III appears to be relatively uncrushed, penultimate phalanx missing and ungual phalanx distorted; F, digit IV (apparently complete). G, digit V (possible morphology) penultimate phalanx missing. H, H1, NHMUK R33: ungual phalanx of digit III of manus in dorsal and ventral views, respectively, showing the expected asymmetrical shape, as in Norman (1986: figs 50, 51). Abbreviations: art, articular facet for penultimate phalanx; c.gr, ungual claw groove. Scale bar = 10 cm.
