NUMBER 1957 AUGUST 5, 1959 Fossil Mammals from the Type Area of the Puerco and Nacimiento Strata, Paleocene of New Mexico BY GEORGE GAYLORD SIMPSON ANTECEDENTS The first American Paleocene mammals and the first anywhere from the early to middle Paleocene were found in the San Juan Basin of New Mexico. Somewhat more complete sequences and larger faunas are now known from elsewhere, but the San Juan Basin strata and faunas are classical and are still the standard of comparison for the most clearly established lower (Puercan), middle (Torrejonian), and upper (Tiffanian) stages and ages. The first geologist to distinguish clearly what are now known to be Paleocene beds in the San Juan Basin was Cope in 1S74. He named them "Puercan marls" (Cope, 1875) on the basis of beds along the upper Rio Puerco, and especially of a section west of the Rio Puerco southwest of the then settlement of Nacimiento and of the present town of Cuba, on the southern side of Cuba Mesa. Cope reported no fossils other than petrified wood, but in 1880 and later his collector, David Baldwin, found rather abundant mammals, described by Cope (1881 and later) in beds 50 miles and more to the west and northwest of the type locality but referred to the same formation. In the 1890's Wortman collected for the American Museum in the Puerco of Cope, and, on the basis of this work, Matthew (1897) recognized the presence of two quite distinct faunas of different ages.

    ANALYSIS AND CORRELATION OF GROWTH STRATA OF THE CRETACEOUS TO PALEOCENE LOWER DAWSON FORMATION: INSIGHT INTO THE TECTONO-STRATIGRAPHIC EVOLUTION OF THE COLORADO FRONT RANGE by Korey Tae Harvey A thesis submitted to the Faculty and Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Geology). Golden, Colorado Date __________________________ Signed: ________________________ Korey Harvey Signed: ________________________ Dr. Jennifer Aschoff Thesis Advisor Golden, Colorado Date ___________________________ Signed: _________________________ Dr. Paul Santi Professor and Head Department of Geology and Geological Engineering ii ABSTRACT Despite numerous studies of Laramide-style (i.e., basement-cored) structures, their 4-dimensional structural evolution and relationship to adjacent sedimentary basins are not well understood. Analysis and correlation of growth strata along the eastern Colorado Front Range (CFR) help decipher the along-strike linkage of thrust structures and their affect on sediment dispersal. Growth strata, and the syntectonic unconformities within them, record the relative roles of uplift and deposition through time; when mapped along-strike, they provide insight into the location and geometry of structures through time. This paper presents an integrated structural- stratigraphic analysis and correlation of three growth-strata assemblages within the fluvial and fluvial megafan deposits of the lowermost Cretaceous to Paleocene Dawson Formation on the eastern CFR between Colorado Springs, CO and Sedalia, CO. Structural attitudes from 12 stratigraphic profiles at the three locales record dip discordances that highlight syntectonic unconformities within the growth strata packages. Eight traditional-type syntectonic unconformities were correlated along-strike of the eastern CFR distinguish six phases of uplift in the central portion of the CFR.

    RE-EVALUATION, Mileposts 149 to 161 Interstate 25 Improvements through the Colorado Springs Area Environmental Assessment PALEONTOLOGY TECHNICAL MEMO April 2012 Prepared for: CDOT Region 2 Prepared by: Doug Eberhart, Telephone (719) 520-5800 Introduction The Colorado Department of Transportation (CDOT) has prepared this technical memorandum to update findings with regards to the paleontological resources described in the original 2004 I-25 Environmental Assessment (EA) with regard to the portion of the Proposed Action between Woodmen Road (Exit 149) in Colorado Springs and State Highway 105 in Monument (Exit 161). The purpose of the EA’s Proposed Action is to relieve existing traffic congestion and address project future congestion on I-25 within the Colorado Springs Urbanized Area. The I-25 EA originally evaluated impacts for the widening of I-25 between South Academy Boulevard (Exit 135) and SH 105, together with reconstruction of various I-25 interchanges within this corridor. Page 2-10 of the EA stated that, “Consistent with projected traffic demand in the I-25 corridor, the conceptual phasing for the Proposed Action calls for: (1) initially six-laning through central Colorado Springs, then (2) six-laning in northern El Paso Figure 1. I -25 EA Re -evaluation Project Vicinity County, and finally (3) adding HOV [High-Occupancy Vehicle] lanes through central Colorado Springs and widening to six lanes south to South Academy Boulevard.” For the year 2012, CDOT has received funding to begin the second phase, meaning to widen I-25 to six lanes in northern El Paso County. The EA calls for eventually widening I-25 all the way to SH105.

    THESIS GEOPHYSICAL CONSTRAINTS ON THE FLEXURAL SUBSIDENCE OF THE DENVER BASIN Submitted by Ayrat Abdullin Department of Geosciences In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Fall 2012 Master’s Committee: Advisor: Dennis L. Harry Sven Egenhoff Michael Lefsky ABSTRACT GEOPHYSICAL CONSTRAINTS ON THE FLEXURAL SUBSIDENCE OF THE DENVER BASIN The Denver Basin is an asymmetric Laramide (Late Cretaceous through Eocene) foreland basin covering portions of eastern Colorado, northwestern Kansas, southwestern Nebraska, and southeastern Wyoming, USA. It is bordered on the west by the Rocky Mountain Front Range Uplift, a basement cored Laramide anticline bounded by thrust faults, and on the east by the Great Plains and stable North American craton. A ~400 mGal negative Bouguer gravity anomaly exists over the Denver Basin and Front Range Uplift, with its minimum located over the highest topography in the central part of the uplift, approximately 100 km west of the Denver Basin. This study examines three hypotheses concerning the isostatic state of the basin and adjacent Front Range Uplift. These hypotheses are that the modern shape of the basin is due to: 1) flexure of the lithosphere under the surface load of the current topography, or 2) flexure under a subsurface load beneath the Rocky Mountains, or 3) a combination of both surface and subsurface loads. To test these hypotheses, spectral analysis and forward gravity modeling was conducted along three profiles located in the northern, central, and southern parts of the basin. Bouguer gravity power spectra along the profiles reveal 5 major density interfaces interpreted to represent the base of the lithosphere (at depths of 132 to 153 km), base of the crust (45-55 km), a mid-crustal boundary (about 20 km), the top of Precambrian basement (1-2 km), and a boundary between the Pierre Shale and Niobrara Formations within the pre-Laramide sedimentary section (-1-0 km).

However, the lack of precise depositional age 24 constraints for the Ojo Alamo Sandstone and lower Nacimiento Formation has hindered our 25 understanding of the timing and pacing of mammalian community change in the SJB following 26 the Cretaceous-Paleogene mass extinction. Here we produced a high-resolution age model for 27 the Ojo Alamo Sandstone and lower Nacimiento Formation combining magnetostratigraphy and 28 40Ar/39Ar geochronology spanning the first ~3.5 Myr of the Paleocene.
