Woolly mammoths were plant‑eaters that mainly grazed on tough grasses and sedges, but they also browsed a variety of other cold‑climate plants such as herbs, shrubs, mosses, and tree material.

Main Diet: Grassy Buffet

Most of a woolly mammoth’s diet came from:

  • Grasses and sedges from the “mammoth steppe” tundra.
  • Small flowering plants (forbs) like buttercup‑type tundra flowers, which were more nutritious than grass.
  • Herbaceous plants growing low to the ground in cold, dry Ice Age landscapes.

Their huge stomachs acted like fermentation vats, breaking down fibrous grass that was otherwise not very nutritious.

Extra Plant Snacks

Stomach contents and preserved dung show that mammoths also ate a mix of other vegetation depending on local conditions. This likely included:

  • Shrubs and small bushes.
  • Mosses and lichens in some regions.
  • Tree material such as bark, twigs, leaves, and other woody parts.

Some remains even indicate they occasionally consumed fruits, berries, and possibly nuts when available in warmer seasons.

How They Got Their Food

Their bodies were adapted for a harsh Ice Age menu.

  • Long, curved tusks helped sweep aside snow, dig up buried grasses, strip bark from trees, and break ice to reach plants and water.
  • Massive, high‑crowned molars with many enamel ridges were perfect for grinding coarse, frozen tundra grasses.
  • Their trunks let them pull up big tufts of grass or delicately pluck buds, flowers, and leaves.

Because they were so large, adults may have eaten hundreds of pounds of plant material per day and spent much of the day feeding.

Baby Mammoths’ First Meals

Evidence from a famously preserved baby mammoth suggests a surprising early‑life diet twist.

  • Calves would have started on mother’s milk like modern elephant calves.
  • At least some baby mammoths also ate adult dung, likely their mother’s, to seed their gut with the right bacteria to digest tough plants later in life.

This behavior matches what is seen in living elephants and other large herbivores that rely on complex gut microbes.

Changing View with New Research

Older ideas emphasized mostly grass, but plant DNA preserved in permafrost has updated the picture.

  • Ancient soil DNA shows Ice Age Arctic landscapes were richer in diverse forbs and small plants than once thought, not just sparse grass.
  • This more varied, higher‑protein plant community would have helped sustain huge herbivores like mammoths, woolly rhinos, and steppe bison.
  • Dental wear and isotope studies back up the idea that mammoths were primarily grazers but still used a flexible, mixed plant diet depending on region and climate.

In short, when people ask “what did the woolly mammoth eat,” the best answer today is: mostly tough steppe grasses and sedges, plus a rotating cast of flowers, shrubs, mosses, and tree parts, with baby mammoths getting a microbial jump‑start from their elders’ dung.
