FIGURE 24. Schematic drawings of metriorhynchid tail flukes, distal caudal columns and integumentary contours. A: Rhacheosaurus NHMUK R.3948, historical reconstruction (Andrews, 1913, figure A). B: Same specimen, outline from photograph (Figure 23B), with potential outlines of the upper lobe evaluated from textures on the fossil in visible light. C: Metriorhynchidae indet., LF 3474 (new specimen, Figure 4), with possible outlines for the upper lobe inferred from preserved edges. D: Proposed outline in ontogenetic stages with less pronounced tail bending (generalized sketch comparable to unpublished specimen, see text for further information). All drawn to similar size.
