“Kangaroos (aka macropods) belong to a large, mostly herbivorous Australasian marsupial clade termed Diprotodontia. Shared characters that unite diprotodontians include diprotodonty (where there are just two lower incisors), a special epitympanic wing of the squamosal bone in the braincase, and the presence of an extra band of fibres (termed the fasciculus aberrans) that connect the two hemispheres of the brain. The monophyly of Diprotodontia is also well supported by molecular characters,” [16] and indicates that Thylacoleo carnifex may have shared ancestry with wombats and kangaroos, which are generally believed to have been herbivores.
