Figure 4 in Locomotion in terrestrial mammals: the influence of body mass, limb length and bone proportions on speed
Figure 4. Regression plots of independent contrasts for hind limb parameters. Log running speed is in km h-1. a, Hind limb length in mm/3÷body mass in kg; b, metatarsus/femur ratio; c, cnemial crest height in mm/3÷body mass in kg; d, calcaneal tuber length in mm/3÷body mass in kg. Regression lines fitted to the contrasts by means of least squares (model I) analysis.

Figure 11 in Thermal physiology and the origin of terrestriality in vertebrates
Figure 11. Rate and amount of heat gain and loss in animals the size of adults of Eusthenopteron, Panderichthys, Acanthostega and Ichthyostega (~1 m), and smaller tetrapods. Ambient water temperature is 20 ∞C, and ambient air temperature is 30 ∞C. On the left, time of emergence from the water, on the right, return to the water.

Figure 5. On the left, amphibian trackway from the Lower Carboniferous (Tournaisian) of the Horton Bluff Formation, Hantsport, Nova Scotia, Redpath Museum, McGill University RM 20.6777. Tail drag indicates that the trackway was made on land. Note similarity with diagram of a trackway from the Upper Carboniferous on the right (from Baird, 1952).
Figure 1. Structural changes between fish and tetrapods. A in Thermal physiology and the origin of terrestriality in vertebrates
Figure 1. Structural changes between fish and tetrapods. A, Eusthenopteron, the most thoroughly known Upper Devonian choanate sarcopterygian (from Andrews & Westoll, 1970). B, Panderichthys, an Upper Devonian fish intermediate between Eusthenopteron and the Upper Devonian amphibians (from Vorobyeva & Schultze, 1991). C, the Upper Devonian amphibian Acanthostega (Coates & Clack, 1995). D, the Upper Devonian amphibian Ichthyostega (from Coates & Clack, 1995). More details of the forelimb have since been discovered (Clack, Blom & Ahlberg, 2003). Animals are reproduced at approximately equal head/trunk lengths.
