  • Woolly mammoths may have starved to death when changes in the climate deprived them of their best food: flowering herbs. Perhaps unexpectedly given their size and the chilly climates they lived in, woolly mammoths are thought to have survived on a diet of steppe grasses. But that's not the whole story. A study of frozen stomach contents and frozen DNA found in the dirt across the Arctic suggests that the ice-age megafauna primarily ate a richer class of plants called forbs.
