Chronology and Faunal Evolution of the Middle Eocene Bridgerian North American Land Mammal “Age”: Achieving High Precision Geochronology Kaori Tsukui Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2016 © 2015 Kaori Tsukui All rights reserved ABSTRACT Chronology and Faunal Evolution of the Middle Eocene Bridgerian North American Land Mammal “Age”: Achieving High Precision Geochronology Kaori Tsukui The age of the Bridgerian/Uintan boundary has been regarded as one of the most important outstanding problems in North American Land Mammal “Age” (NALMA) biochronology. The Bridger Basin in southwestern Wyoming preserves one of the best stratigraphic records of the faunal boundary as well as the preceding Bridgerian NALMA. In this dissertation, I first developed a chronological framework for the Eocene Bridger Formation including the age of the boundary, based on a combination of magnetostratigraphy and U-Pb ID-TIMS geochronology. Within the temporal framework, I attempted at making a regional correlation of the boundary-bearing strata within the western U.S., and also assessed the body size evolution of three representative taxa from the Bridger Basin within the context of Early Eocene Climatic Optimum. Integrating radioisotopic, magnetostratigraphic and astronomical data from the early to middle Eocene, I reviewed various calibration models for the Geological Time Scale and intercalibration of 40Ar/39Ar data among laboratories and against U-Pb data, toward the community goal of achieving a high precision and well integrated Geological Time Scale. In Chapter 2, I present a magnetostratigraphy and U-Pb zircon geochronology of the Bridger Formation from the Bridger Basin in southwestern Wyoming. -

Fort Davy Crockett: Browns Park National Wildlife Refuge (Colorado)
U.S. FISH AND WILDLIFE SERVICE: REGION 6 - CULTURAL RECOURSE PROGRAM Fort Davy Crockett?: An Archaeological Mystery Browns Park National Wildlife Refuge – Northwest Colorado Summarized from: A Report on the Results of Limited Subsurface Testing at 5MF5478, a Proposed Site of Historic Fort Davy Crockett, Moffat County, Colorado Kristen D. Kent and Mona C. Charles, Department of Anthropology, Fort Lewis College, Durango, Colorado December 2004 Introduction The follow excerpts are from a 2004 report documenting archaeological testing at the possible location of Fort Davy Crocket on the Brown’s Park National Wildlife Refuge. Many studies and much research has been conducted over the years to try and determine if the remains found on a bluff overlooking the Green River on the Browns Park National Wildlife Refuge are indeed those of the Fort. This research adds additional insight into the mystery. Fort Davy Crockett In 1837 three fur trappers, Prewett Sinclair, Philip Thompson, and William Criag, formed a partnership and reportedly built Fort Davy Crockett that same year. The Fort was named after the famous Tennessee frontiersman who died at the Battle of the Alamo in Texas the previous year. Kit Carson, another famous frontiersman, trapper and scout is reported to have been employed by the owners of Fort Davy Crockett. In 1839 members of the Peoria Party on their way to Oregon reported staying at the Fort. A description of the Fort was provided in the recordings of Thomas Jefferson Farnham, leader of the Peoria Party. He described the Fort thus: The fort, as it is called, peered up in the centre, upon the winding banks of the Sheetskadee. -

The site documents a fauna of Early Jurassic nektonic marine animals (five species of fishes, one species of marine crocodilian, two species of ichthyosaurs, cephalopods and crustaceans), but also over 20 spe- cies of insects. Unlike other fossil sites of similar age, the 3D preservation at Strawberry Bank provides unique evidence on palatal and braincase structures in the fishes and reptiles. The age of the site is important, documenting a marine ecosystem during recovery from the end-Triassic mass extinction, but also exactly coincident with the height of the Toarcian Oceanic Anoxic Event, a further time of turmoil in evolution. -
SVP's Letter to Editors of Journals and Publishers on Burmese Amber And
Society of Vertebrate Paleontology 7918 Jones Branch Drive, Suite 300 McLean, VA 22102 USA Phone: (301) 634-7024 Email: [email protected] Web: www.vertpaleo.org FEIN: 06-0906643 April 21, 2020 Subject: Fossils from conflict zones and reproducibility of fossil-based scientific data Dear Editors, We are writing you today to promote the awareness of a couple of troubling matters in our scientific discipline, paleontology, because we value your professional academic publication as an important ‘gatekeeper’ to set high ethical standards in our scientific field. We represent the Society of Vertebrate Paleontology (SVP: http://vertpaleo.org/), a non-profit international scientific organization with over 2,000 researchers, educators, students, and enthusiasts, to advance the science of vertebrate palaeontology and to support and encourage the discovery, preservation, and protection of vertebrate fossils, fossil sites, and their geological and paleontological contexts. The first troubling matter concerns situations surrounding fossils in and from conflict zones. One particularly alarming example is with the so-called ‘Burmese amber’ that contains exquisitely well-preserved fossils trapped in 100-million-year-old (Cretaceous) tree sap from Myanmar. They include insects and plants, as well as various vertebrates such as lizards, snakes, birds, and dinosaurs, which have provided a wealth of biological information about the ‘dinosaur-era’ terrestrial ecosystem. Yet, the scientific value of these specimens comes at a cost (https://www.nytimes.com/2020/03/11/science/amber-myanmar-paleontologists.html). Where Burmese amber is mined in hazardous conditions, smuggled out of the country, and sold as gemstones, the most disheartening issue is that the recent surge of exciting scientific discoveries, particularly involving vertebrate fossils, has in part fueled the commercial trading of amber. -
