Pelvic morphology in the extant sexually-dimorphic fallow deer Dama dama compared to that of male Maiacetus inuus.
Pelves are viewed ventrally. Sexes differ in the shape of the notch separating inferior rami of left and right pubes. (A)– Female Dama dama has the more U-shaped pubic notch labeled in red. (B)– Male Dama dama has the more V-shaped pubic notch labeled in red. (C)– Male Maiacetus inuus, GSP-UM 3551, has the V-shaped pubic notch labeled in red. Drawings of Dama dama are from [29]. Part of the right pubic ramus of GSP-UM 3551 is restored from the left side.
