This must mean that, relative to skull size, the Agriotherium with the 465.0 mm skull was lighter than the Arctodus with the 463.0 mm skull, since Arctodus's skull was smaller in proportion to body size. Nevertheless, it is not the largest of the predatory land mammals, with some like Megistotherium exceeding it slightly, and the largest bears like Arctodus and Agriotherium were noticeably larger despite having smaller skulls.
