Woolly mammoths, these iconic Ice Age giants, roamed the earth thousands of years ago. But what did woolly mammoths eat to fuel their massive bodies? This article will delve into the diet of these prehistoric creatures, exploring their feeding habits and the environment that sustained them. We’ll also touch upon how their diet contributed to their eventual extinction.
The Woolly Mammoth’s Herbivorous Diet
Woolly mammoths were herbivores, meaning their diet consisted entirely of plants. Their primary food source was grass, which was abundant in the steppe-tundra environment they inhabited. This landscape, a mix of grasslands and tundra, provided a rich variety of vegetation for the mammoths to graze on. Imagine vast expanses covered with grasses, sedges, forbs, and flowering plants – a veritable buffet for these massive creatures. They likely consumed hundreds of pounds of vegetation daily to maintain their enormous size.

What Kinds of Plants Did They Eat?
While grasses formed the bulk of their diet, woolly mammoths weren’t picky eaters. They also consumed other types of plants, including:
- Sedges: These grass-like plants are common in wetland areas.
- Forbs: This broad category includes various herbaceous flowering plants.
- Twigs and bark: During leaner times, or perhaps for variety, mammoths would browse on woody vegetation.
How Do We Know What Woolly Mammoths Ate?
Scientists have several ways to determine the diet of extinct animals like the woolly mammoth:
- Fossil Stomach Contents: Occasionally, well-preserved mammoth carcasses are discovered with undigested plant material in their stomachs, providing direct evidence of their last meals.
- Fossil Dung: Analyzing fossilized mammoth dung, called coprolites, reveals the types of plants they consumed.
- Tooth Wear: The microscopic scratches and wear patterns on mammoth teeth offer clues about the types of plants they were grinding.
- Isotope Analysis: Studying the isotopes in mammoth bones and tusks can provide information about the types of plants they ate and the environment they lived in.
How Much Did a Woolly Mammoth Eat?
A fully grown woolly mammoth could weigh up to six tons, so it needed a substantial amount of food to sustain itself. Estimates suggest they ate between 400 to 600 pounds of vegetation every day. That’s like eating a small car’s worth of plants!

Did Climate Change Affect Their Diet?
As the climate changed at the end of the last Ice Age, the steppe-tundra environment began to shrink, and forests expanded. This shift likely impacted the availability of the mammoths’ preferred food sources, contributing to their decline.

Conclusion
Woolly mammoths were remarkable herbivores adapted to a harsh environment. Their diet, primarily consisting of grasses and other vegetation, played a crucial role in their survival. Understanding what woolly mammoths ate provides valuable insights into their ecological role and the factors that contributed to their extinction. The changing climate and subsequent dwindling food supply likely played a significant role in the disappearance of these magnificent creatures.
