Fossil skull of an extinct giant marmot with long incisors and two rows of five black colored teeth. Photographed upside down on a square piece of thick black foam, with five other boxes of specimens in the background on white foam. The bones have the color of brown weathered rock.
The giant marmot (Paenemarmota barbouri) is the largest known member of the squirrel family. Like other species of marmot, they may have eaten grasses, flowers, grains, and other plants, preferred open grassland habitats, and hibernated through winter. This fossil dates to the Pliocene Epoch in Hagerman, about 4 to 3 million years ago.
