Fig. 4 in Body mass estimation in Triassic cynodonts from Argentina based on limb variables

Fig. 4. Logarithmic scale representation of the body mass ranges of adult forms of amniotes Chañares and Ischigualasto formations, Triassic of Argentina. Body masses for Cynognathia obtained in this work (black silhouettes) compared with other amniotes known from these formations (white silhouettes). Cynodonts Chiniquodon sanjuanensis Martínez and Forster, 1996, and Probainognathus jenseni Romer, 1970; the dicynodont Dinodontosaurus brevirostris Cox, 1968; and archosauriforms Lagerpeton chanarensis Romer, 1971a, Chanaresuchus sp. (includes C. bonapartei Romer, 1971b, and C. ischigualastensis Trotteyn, Martínez and Alcober, 2012), paracrocodylomorphs and the dinosaur Herrerasaurus ischigualastensis Reig, 1963. The horizontal length of the rectangles represents the body mass range for the genus. The silhouettes are not to scale.
