“…The distributions of extant and fossil Amphiuma, Siren, Necturus and Batrachosauroides each provide direct congeneric connections between the Early Cenozoic WICP and the Late Cenozoic SECP. Our ancestral area reconstructions suggest that the ancestors of Amphiuma, Siren and Batrachosauroides dispersed from the WICP (before it became completely arid at the close of the Eocene [12,42]) to the emerging Oligocene/Miocene SECP [11]. It is also possible that undiscovered fossil taxa more closely related to extant lineages occurred on the Figure 2.…”

“…Extreme sea-level fluctuations and global temperature shifts since the Late Cretaceous have had major impacts on the freshwater coastal plain habitats of North America [11,12]. The most drastic effects include the complete regional shift from the ancestral Western Interior Coastal Plain (WICP; Late Cretaceous to Eocene) to the modern Southeastern Coastal Plain (SECP; Oligocene to present; figure 1 map).…”

“…Sea level is based on Miller et al [13] and indicates a substantial decline from the end of the Cretaceous through the Palaeocene, unveiling the ancestral WICP, followed by exposing the modern SECP after the Eocene. The height of the Eocene sea level (dashed line) is based on Galloway [11].…”

Biogeography and body size shuffling of aquatic salamander communities on a shifting refuge

Freshwater habitats of coastal plains are refugia for many divergent vertebrate lineages, yet these environments are highly vulnerable to sea-level fluctuations, which suggest that resident communities have endured dynamic histories. Using the fossil record and a multi-locus nuclear phylogeny, we examine divergence times, biogeography, body size evolution and patterns of community assembly of aquatic salamanders from North American coastal plains since the Late Cretaceous. At least five salamander families occurred on the extensive Western Interior Coastal Plain (WICP), which existed from the Late Cretaceous through the Eocene. Four of these families subsequently colonized the emergent Southeastern Coastal Plain (SECP) by the Early Oligocene to Late Miocene. Three families ultimately survived and underwent extensive body size evolution in situ on the SECP. This included at least two major size reversals in recent taxa that are convergent with confamilial WICP ancestors. Dynamics of the coastal plain, major lineage extinctions and frequent extreme changes in body size have resulted in significant shuffling of the size structure of aquatic salamander communities on this shifting refuge since the Cretaceous.

“…High-precision radioisotopic dating of the Ogallala Formation and comparison with dated tectonic and marine isotopic events may help to illuminate the causes of Ogallala Formation aggradation, enhance the western US climatic record, and strengthen the temporal precision of the North American Land Mammal Ages (NALMAs). In this work, it is also shown that temporal resolution of LA-ICP-MS dating is adequate for the evaluation of two models of Ogallala Formation aggradation: deposition as an alluvial plain (Johnson, 1901;Smith, 1940;Frye and Leonard, 1964), or aggradation as diachronous, avulsing lobes (Seni, 1980;Skinner and Johnson, 1984;Chapin, 2008;Galloway et al, 2011;Harlow, 2013), termed distributive fluvial systems by Weissmann et al (2010). These models predict different stratigraphic architectures and three-dimensional arrangements of high and low hydraulic conductivity units, so this information is prerequisite to the planned development by the Kansas Geological Survey (KGS) of more accurate groundwater flow models designed to assess the water resources of the rapidly declining Ogallala-High Plains aquifer.…”

Difficulties in correlation within continental clastic basins arise from the common shortage of reliable marker beds, which limits characterization of geological relationships. In the High Plains of the central United States, an improved understanding of the stratigraphic architecture of the terrestrial Ogallala Formation can be used to improve management of depleted groundwater resources, illuminate the causes of fluvial aggradation, enhance the western US climatic record, and strengthen the temporal precision of the North American Land Mammal Ages. Such relationships can be derived from chronostratigraphic information provided by abundant, dateable, volcanogenic zircon in volcanic ashes and fluvial beds, which provide the first highprecision (ca. 1-5% uncertainty) radioisotopic dates for the Ogallala Formation. These zirconbearing ashes appear to have travelled ~1350 km from their interpreted sources within the Bruneau-Jarbidge and Twin Falls volcanic centers in Idaho, suggesting that volcanogenic zircon has the previously unappreciated potential to time-stamp terrestrial surfaces at great distances from contemporaneous magmatic centers. Volcanic ash depositional ages are consistent with fluvial maximum depositional ages, indicating that deposition of common lithologies within the Ogallala Formation, including sands, paleosols, and volcanic ashes can be reliably dated with modern, high-precision techniques. Zircon U-Pb LA-ICP-MS results suggest diachronous aggradation of the Ogallala Formation in Kansas, particularly deposition of an inferred Norton lobe in northern Kansas that initiated prior to ~12.5 Ma and aggraded to near-modern levels by 11.7 Ma, measurably earlier than the ~8-9.5 Ma deposition of an inferred Ellis lobe over a bedrock high in central Kansas. The observed diachronous relationships predict aquifer anisotropy that could inform efforts to develop numerical groundwater models designed to forecast aquifer response to different conservation strategies. iv ACKNOWLEDGEMENTS

Geodynamic models of mantle convection predict that Mexico and western North America share a history of dynamic support. We calculate admittance between gravity and topography, which indicates that the elastic thickness of the plate in Mexico is 11 km and in western North America it is 12 km. Admittance at wavelengths > 500 km in these regions suggests that topography is partly supported by subcrustal processes. These results corroborate estimates of residual topography from isostatic calculations and suggest that the amount of North American topography supported by the mantle may exceed 1 km. The Cenozoic history of magmatism, sedimentary flux, thermochronometric denudation estimates, and uplifted marine terraces imply that North American lithosphere was uplifted and eroded during the last 30 Ma. We jointly invert 533 Mexican and North American longitudinal river profiles to reconstruct a continent-scale rock uplift rate history. Uplift rate is permitted to vary in space and time. Erosional parameters are calibrated using incision rate data in southwest Mexico and the Colorado Plateau. Calculated rock uplift rates were 0.15-0.2 mm/yr between 25 and10 Ma. Central Mexico experienced the highest uplift rates. Central and southern Mexico continued to uplift at 0.1 mm/yr until recent times. This uplift history is corroborated by independent constraints. We predict clastic flux to the Gulf of Mexico and compare it to independent estimates. We tentatively suggest that the loop between uplift, erosion, and deposition can be closed here. Mexico's staged uplift history suggests that its dynamic support has changed during the last 30 Ma.
