Figure 1. Comparing the body plans of semi-aquatic thalattosuchians (A–C) with that of a fully aquatic metriorhynchid (D). A, the teleosaurid teleosauroid Platysuchus multiscrobiculatus, holotype SMNS 9930; B, the machimosaurid teleosauroid Macrospondylus bollensis, referred specimen NMW 13445; C, the early diverging metriorhynchoid Pelagosaurus typus, referred specimen FWD 0784; D, the metriorhynchid Cricosaurus suevicus, lectotype SMNS 9808.

Figure 16 in The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics

Figure 16. Principle coordinates morphospace subdivided into four time bins: (A) Middle Jurassic (Bajocian–Callovian); (B) Oxfordian–Kimmeridgian; (C) Tithonian; (D) Early Cretaceous (Berriasian–Valanginian). The black ellipse contains the metriorhynchine taxa, whereas the grey ellipse contains the Geosaurinae.

Figure 7. Metriorhynchoidea phylogeny, with dental characters mapped. The thin branches refer to smooth carinated crowns, whereas the bold black lines refer to denticulate carinae. The bold grey indicates crowns lacking carinae. The symbols refer to tooth morphology guilds from Massare (1987) and Ciampaglio et al. (2005).

Figure 3 in The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics

Figure 3. Metriorhynchoidea phylogeny, with character complexes relating to marine adaptation mapped by shading. The light-grey shading indicates taxa demonstrating the 'typical' adaptations of metriorhynchids, i.e. hypocercal tails, no osteoderms, and no external mandibular fenestrae. The mid-grey shading refers to taxa with dorsally inclined paroccipital processes and verticalized squamosals; whereas the dark-grey shading highlights taxa with streamlined crania (lateral processes of the frontal reoriented caudally, creating an acute angle between the medial and lateral processes of the frontal) and more flattened humeri.

Figure 6 in The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics

Figure 6. Lateral aspect cranial reconstructions, with the muscle line of action indicated: (A) Teleidosaurus calvadosii (modified from Eudes-Deslongchamps, 1867–1869); (B) Metriorhynchus superciliosus (composite based upon specimens from NHM and MNHN). The broken line represents the musculus pseudotemporalis–intramandibularis, whereas the solid black line is the musculus depressor mandibulae. The pterygoids are reconstructed based upon teleosaurids.

Figure 15 in The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics

Figure 15. Rarefaction plots for two metrics (sum of ranges and sum of variances) that measure metriorhynchoid disparity (all taxa) throughout time. A, sum of ranges. B, sum of variances. The sum of variances shows little obvious relationship with sample size, in keeping with the theoretical robustness of the measure to differences in sample size (see Wills et al., 1994). The sum of ranges curve suggests that, although this measure is highly sensitive to sample size (Wills et al., 1994), the patterns for metriorhynchoids are robust. Notably, the relative ordering of disparity measures from high (Tithonian) to low (Bathonian) is seen at all sample sizes, from N = 3 upwards. Abbreviations: B, Bathonian; C, Callovian; EK, Early Cretaceous; K, Kimmeridgian; O, Oxfordian; T, Tithonian.

Figure 5. Postcranial marine adaptations of metriorhynchids (Rhacheosaurus gracilis NHM R.3948): (A) tail fluke with an impression of the fleshy upper lobe (the only specimen preserving this feature); (B) hindlimbs, note the high proportion that the pes makes, compared with the tibia–fibula, and how poorly developed the pelvis is.
