Marmota flaviventris (yellow-bellied marmot)
| Diet | herbivore (primarily) |
| Habitat | rocky outcrops near grass/forbs |
| Description | Largest ground squirrel, tan brown, frosted. White on face, dark bar across nose. |
| Skull Characteristics | Largest squirrel, skull length >70mm. Otherwise similar to other ground squirrels: Zygomatic arches are twisted and flattened horizontally and converge toward the front, with a more streamlined appearance than tree squirrels, good for squeezing through burrows. Postorbital process projection is often narrow and fragile. In the mandible, the notch between the coronoid process and the condyloid process is deeper in ground squirrels than in tree squirrels. |
