Prehistoric predators kept large animals in check, shaped ecosystems

OSU Press Release, Oct. 26, 2015: “Large predators can have a major role in limiting their prey and in determining the structure and function of ecosystems,” said Ripple. “But scientists have thought that the largest herbivores, such as elephants, were immune from predation. We now know that’s not the case, and based on these data from the Pleistocene (the epoch which lasted from about 2.5 million to 11,700 years ago), we now think that large carnivores did limit the large herbivores at that time.”
