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 14 in The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics
Figure 14. The disparity (morphological diversity) of metriorhynchoids through time, based on two metrics (sum of ranges and sum of variances, derived from a PCO analysis; see text for details). A, B, disparity of all metriorhynchoids through time. C, D, disparity of metriorhynchines through time. E, F, disparity of geosaurines through time. Squares represent the disparity metric and error bars denote 95% confidence intervals, based on bootstrapping. There are no error bars for the Early Cretaceous geosaurines because of the small sample size (N = 2).
