... evolution, shifts in geographic range, and by altering their community composition. Here, we evaluate the relationship between tectonic episodes and the diversification history of fossil mammals in the Miocene Dove Spring Formation (12.5–8.5 Ma) of southern California, USA. This formation contains a rich...

...DAVID P. WHISTLER; DOUGLAS W. BURBANK Abstract The Dove Spring Formation (DSF) is an 1,800-m-thick succession of fluvial, lacustrine, and volcanic rocks that contains a nearly continuous sequence of diverse vertebrate fossil assemblages. When the North American provincial mammalian ages were...

Stratigraphy of the Dove Spring Formation with updated correlations based on recalibrated radiometric dates. Top of formation is based on new tephrochronologic correlation by Knott et al. (2022). Columns labeled W92 are modified from Whistler and Burbank (1992). Magnetic polarity stratigraphy is from Whistler et al. (2009). Magnetic polarity time scale is modified from Hilgen et al. (2012). Lateral distance between first and last columns is ~8 km.

Temporal distribution of large mammals from the Dove Spring Formation. Stratigraphic occurrences of fossil taxa are denoted by black points. Thick vertical lines represent observed residence time with thin vertical lines indicating 80% confidence intervals with endpoints indicated by white triangles. Unbiased point estimates of first and last occurrences are indicated by horizontal tick marks. Tectonic episodes are marked by gray zones to indicate uncertainty in the timing of their initiation. Numbers correspond to taxon names listed in Table A1.

Standing richness of the Dove Spring Formation, excluding singletons due to their high dependence on preservation, resulting in a maximum species richness of 40, which is lower than the raw count (45). These plots incorporate range-through taxa and provide a better estimate of actual richness than the raw occurrence counts in Figure 4B. Both the observed and estimated fossil records follow a unimodal pattern.

Taxonomic composition of large mammals in the Dove Spring Formation through time, including singletons. (A) Stacked richness of family-level species richness. (B) Change in log-likelihood ratios (delta LnL) of large-mammal assemblage composition. Values of 2.0 or greater indicate statistically significant change in faunal composition for a given time interval compared to the previous interval. The 10.5 Ma peak is driven by the first appearances of Barbourofelidae and Mustelidae, as well as additional species of Antilocapridae, Camelidae, and Canidae. The 8.5 Ma peak is the result of species loss in the Canidae, Equidae, Gomphotheriidae, and Mustelidae. An additional peak at 12.1 Ma was driven by the first appearances of Amphicyonidae, Canidae, and Rhinocerotidae, but the delta LnL values of this peak do not reach the threshold of statistical significance.

(A) Sediment accumulation rate (SAR) and preservation rate for the El Paso Basin. We removed a pair of basalt flows from our calculations to more accurately represent the basin’s mode of sediment accumulation. As a result, SAR was lower near 11.0 Ma, and a moderate peak is no longer present. (B) Large mammal (>1 kg) fossil specimens recovered from the Dove Spring Formation, number of localities, and species richness are based on raw observed occurrence data, excluding range-through taxa. Specimens recovered from the base of the formation are represented by points at 12.5 Ma. Tectonic episodes that began during the study interval are marked with gray zones to indicate uncertainty in the timing of their initiation.

Simplified geologic map of the central and eastern Garlock fault (California, USA). Inset map shows the Garlock fault (thickest line), Figure 1 area (red line), geologic provinces, other features, and the border between California (CA) and Nevada (NV). Previously published total offset constraints for the Garlock fault are shown in bold text (see Table 1 for abbreviations and descriptions). Fault abbreviations: BF—Blackwater fault; WGF—western Garlock fault; BM—Black Mountain; DSF—Dove Spring Formation; ECDS—Eagle Crags dike swarm; MDS—megacrystic dike swarm; and SESD—Southeast Sierra dikes. Geology modified from Walker et al. (2002). Holocene and upper Pleistocene units are shown as white.

Shaded relief map of the southwestern United States from the western Great Plains on the right (east) to the Pacific Coast of California at far left. Northern Gulf of California and Baja Peninsula at lower left. The Southern Rocky Mountains, Rio Grande rift, and Colorado Plateau make up the high topography at center. Selected middle and upper Miocene terrestrial sedimentary deposits (red) were compiled from numerous sources cited in text and Appendix 1. Miocene basins in the Basin and Range province of Arizona and southwestern New Mexico are partly obscured by widespread gravel-covered pediments and Pliocene-Quaternary alluvial deposits. Only basins with published Miocene surface or subsurface stratigraphic data are shown. Exposures in Arizona are from Scarborough (1989) and those in southwestern New Mexico modified from Wilks (2005). Monterey Formation and equivalent Miocene deposits of onshore California are shown in blue (from Graham and Williams, 1985, and Williams, 1988). Blue contour lines show the percentage of annual precipitation provided by the North American Monsoon in July, August, and September for the 26-yr period 1963–1988 (from Higgins et al., 1999).

Figure 5. Map of California showing locations of the three OHV pilot study areas and other OHV areas where site visits were made during development of the updated standard/guidelines. Hollister Hills SVRA is underlain primarily by Tertiary-age fine-grained sandstone, siltstone, and shale in fault contact with older granite and schist typical of the Coast Ranges. The Foresthill OHV area is composed of a variety of Sierra Nevada rock formations, including Tertiary volcanics, metamorphosed sedimentary rocks, serpentinite, and other ultramafic rocks. The Dove Springs OHV Area is underlain predominantly by erodible Quaternary alluvial fan deposits, tuffs, and volcanic mudflows in a semi-arid desert environment. Other sites visited by CGS included a diverse set of ecosystems with multiple soil and vegetation types representative of the state's complex topographic, geologic, and climatic framework.
