Deinotheres for lunch? A sabertooth’s tough-skinned diet
The early Pleistocene of Africa was a time when modern species of large mammals coexisted with others that are no longer with us, creating an exciting mosaic of animal diversity. Sabertooth cats like Homotherium were still at large, but many of the animals they preyed upon were of modern type, from horses to antelopes. But now and then they would come across an elephant-like creature that had long become extinct in Europe and Asia: Deinotherium.
Deinotheres are classified, like elephants, in the order proboscidea, but they belonged in a family of their own, the Deinotheriidae, which probably diverged from the lineage of elephants very early on.
Deinotheres had elephant-like body proportions but their tusks emerged from the mandible rather than from the maxilla, and they curved downwards.
If deinotheres had tight societies like those of modern elephants, it would be very hard for predators to catch a young individual -hard, but not impossible. Even lions manage to snatch a young elephant every now and then in spite of the adults’ almost constant vigilance.
But once the elephantine prey was down, the advantage of the sabertooths over the lions would become evident. With their long, flattened and coarsely serrated upper canines homotheres would be able to pierce their prey’s though skin and even reach the blood vessels underneath. That would be good for the predators, who saved a lot of time, effort and risk, and merciful for the deinothere, who would die from massive blood loss in a couple of minutes. Lions hunting elephants, on the other hand, can take ages to finally kill their prey, who in some occasions is virtually and slowly eaten alive. Bloody as the sabertooth kill was, it would be, in a way, much cleaner than that of its modern relatives, at least when it came to thick-skinned prey.
