FIGURE 2 in Biostratigraphy and biochronology of late Cenozoic North American rodent assemblages

FIGURE 2. Depositional basin framework on which chronological ordering of assemblages (= localities) in Supplementary Material is mostly based. See Supplementary Material and text for full rodent communities, locality data, and information sources. LSD = lowest stratigraphic datum, HSD = highest stratigraphic datum. LSDs and HSDs are regional basin limits, but may also represent global limits (highest or lowest records anywhere in North America). Esr = estimated age based on sedimentation rate from Hart and Brueseke, 1999), ft = fission track date from Walkup et al., 2016), CMZ = Cenozoic Mammal Zone, xxx... = dated volcanic ash beds.
