Figure 46 in Cretaceous Crocodyliforms from the Sahara

Figure 46. Flesh reconstruction of three growth stages in the crocodyliform Araripesuchus wegeneri. Flesh reconstruction shows upright limb posture and an osteoderm-sheathed tail with convergent proximal keels and median distal paddle. Th e pose depicted is the forelimb support phase of a symmetrical bounding gallop, the gait pattern observed in Crocodylus johnstoni and juveniles of other species within the genus. The flesh reconstructions are based on specimens, in which we measured (or estimated) "trunk length" (= length of the dorsosacral column), "forelimb length" (= sum of humerus, radius, radiale, and metacarpal 3 lengths), and "hind limb length" (= sum of femur, tibia, and metatarsal 3 lengths). A Juvenile (̴48 cm or 60% adult length) with proportions based on a juvenile specimen of Araripesuchus gomesii (AMNH 45550; Hecht 1991), in which forelimb and hind limb length comprise 68% and 98%, respectively, of trunk length. B Subadult (̴66 cm or 80% adult length) with proportions based on a subadult specimen of Araripesuchus wegeneri (MNN GAD20) (Fig. 23). C Adult (̴81 cm) with proportions based on an adult skeleton (MNN GAD21) (Fig. 23), in which forelimb and hind limb length comprise 50% and 75%, respectively, of trunk length.
