3D model of the GAR IVE specimen (a), and frontal (b, red), axial (c, blue) and sagittal (d, green) planes of section to illustrate the morphology of the hole (orange arrow) located in the area of the mental foramen. Its inner negative imprint shows a complex shape which is little compatible with the shape of a carnivore tooth (c). To note an additional convoluted shape represented in green in 3D (pink arrow).
