I studied all sciurid taxa exclusive of Marmota; information on the latter genus, as included in this chapter, was kindly provided by A. D. Barnosky. Site collections were sampled with the following coverage:
1. Incomplete but extensive samples of mostly well-preserved specimens (partial to complete skulls, maxillae and dentaries with teeth) from VR-DMNH and MS, with fragmentary specimens of poorly represented taxa and horizons also included.
3. Large, nearly exhaustive sample from the Pit (all specimens known to us from stratified contexts in the Pit; surface collections were incompletely studied).
4. Small but exhaustive (insofar as I could determine) samples from other sites (BR, CAR, FFA, GD, and WH).
