Diet

The earliest mammoth species like M. subplanifrons and M. rumanus were mixed feeders (both browsing and grazing) to browsers. Over the course of mammoth evolution in Eurasia, their diet shifted towards mixed feeding-grazing in M. trogontherii, culminating in the woolly mammoth, which was largely a grazer, with stomach contents of woolly mammoths suggesting that they largely fed on grass and forbs. M. columbi is thought to have been a mixed feeder.
