“…2 of the main text. It is important to note that these stratigraphic intervals are not of equal duration -age constraints across these intervals are derived from correlation with ammonite biozones in the down-dip Mancos Shale, which have been age-constrained by radiometric dating of volcanic ash beds (Gill & Hail Jr, 1975;) -see recent review by Seymour and Fielding (2013) .…”

Quantitative reconstruction of palaeohydrology from fluvial stratigraphy provides sophisticated insights into the response, and relative impact, of tectonic and climatic drivers on ancient fluvial landscapes. Here, field measurements and a suite of quantitative approaches are used to develop a four-dimensional (space and time) reconstruction of palaeohydrology in Late Cretaceous palaeorivers of central Utah, USA-these rivers drained the Sevier mountains to the Western Interior Seaway. Field data include grain-size and cross-set measurements and span 5 parallel fluvial systems, 2 of which include up-dip to down-dip transects, across 7 stratigraphic intervals through the Blackhawk Formation, Castlegate Sandstone and Price River Formation. Reconstructed palaeohydrological parameters include fluvial morphologies (flow depths, palaeoslopes, palaeorelief, and planform morphologies) and various hydrodynamic properties (flow velocities, water discharges, and sediment transport modes). Results suggest that fluvial morphologies were similar in space and time; median flow depths spanned 2-4 m with marginally greater flow depths in southerly systems. Meanwhile palaeoslopes spanned 10-3 to 10-4 , decreasing downstream by an order of magnitude. The most prominent spatio-temporal change is an up to 4-fold increase in palaeoslope at the Blackhawk-Castlegate transition; associated alluvial palaeorelief is 10s of metres during Blackhawk deposition and >100 m during Castlegate Sandstone deposition. Unit water discharges do not change at the Blackhawk-Castlegate transition, which argues against a climatically driven increase in palaeoslope and channel steepness. These findings instead point to a tectonically driven palaeoslope increase, although one limitation in this study is uncertainty in palaeochannel widths, which directly influences total water discharges. These reconstructions complement and expand on extensive previous work in this region, which enables us to test the efficacy of quantitative reconstruction tools. Comparison of results with facies-based interpretations indicates that quantitative tools work well, but inconsistencies in more complex reconstructions (e.g. planform morphologies) highlight the need for further work.

“…The age range of the Mesaverde Group and its constituent units has been interpreted primarily from the ammonite fauna contained in the marine portions of the Blackhawk and in the Mancos Shale, with which it is interbedded to the east. Hampson (2010), Aschoff and Steel (2011) and Seymour and Fielding (2013) provided overviews of the biostratigraphic and other work that has been carried out on these rocks since mapping began in the 1920s. Three of the ammonite zones can be correlated to the global time scale, providing numerical-age tie points.…”

“…This is close to the time range of low-frequency orbital cycles (the so-called 4 th -order cycles), although there is nothing about the thickness or arrangement of the submembers to suggest the regularity that is normally associated with orbital cyclicity.

Observations of modern sedimentation rates in nonmarine and shallow-marine clastic environments indicate that deposits formed in comparable settings in the ancient record could accumulate in a fraction of the time that would appear to be available according to conventional chronostratigraphic dating methods. Typically as little as 10% of elapsed time is represented by sediment, the remainder by breaks in sedimentation, many of which are inconspicuous. In the Book Cliffs of eastern Utah, ravinement surfaces may each account for up to 10 5-years of missing time. Coastal deltaic and nonmarine successions are considered to be particularly fragmentary. In the sedimentary record of shallow-marine and nonmarine deposits stratigraphic continuity is not to be expected, and calculation of time-related issues, such as mass-balance transport rates and the trajectories of shoreline transgression and regression must take this into account.
