Woolly mammoths, rhinos and other ice age beasts may have munched on high-protein wildflowers called forbs, new research suggests.
And far from living in a monotonous grassland, the mega-beasts inhabited a colorful Arctic landscape filled with flowering plants and diverse vegetation, the study researchers found.
The new research "paints a different picture of the Arctic," thousands of years ago, said study co-author Joseph Craine, an ecosystem ecologist at Kansas State University. "It makes us rethink how the vegetation looked and how those animals thrived on the landscape."

The ancient ecosystem was detailed today (Feb. 5) in the journal Nature.
Pretty landscape
In the past, scientists imagined that the now-vast Arctic tundra was once a brown grassland steppe that teemed with wooly mammoths, rhinos and bison. But recreations of the ancient Arctic vegetation relied on fossilized pollen found in permafrost, or frozen soil. Because grasses and sedges tend to produce more pollen than other plants, those analyses produced a biased picture of the landscape. [Image Gallery: Ancient Beasts Roam an Arctic Landscape]
To understand the ancient landscape better, researchers analyzed the plant genetic material found in 242 samples of permafrost from across Siberia, Northern Europe and Alaska that dated as far back as 50,000 years ago.
