Figure 1

Analysis of interspecific allometry. Bivariate graphs derived from the multivariate regressions performed from the Pco against the Log-Cs for the pelvis (A), femur (C), and tibia (E). The three-dimensional models showing the associated size-related shape change (SRSC) for the pelvis (B [lateral view]), femur (D [caudal view]) and tibia (F [caudal and lateral views]) are also shown. Symbols: red squares, Ailuridae; green squares, Amphicyonidae; black stars, Barbourofelidae; black circles, Canidae; empty stars, Creodonta; red circles, Felidae; yellow triangles, Hyaenidae; blue triangles, Mustelidae; green triangles, Nimravidae; yellow circles, Procyonidae; blue squares, Ursidae. See Additional file 3: Table S1 for the species labels. For the interactive three-dimensional shape models explained by size variation see Additional file 1.
