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. -
Species Concepts and the Evolutionary Paradigm in Modern Nematology
JOURNAL OF NEMATOLOGY VOLUME 30 MARCH 1998 NUMBER 1 Journal of Nematology 30 (1) :1-21. 1998. © The Society of Nematologists 1998. Species Concepts and the Evolutionary Paradigm in Modern Nematology BYRON J. ADAMS 1 Abstract: Given the task of recovering and representing evolutionary history, nematode taxonomists can choose from among several species concepts. All species concepts have theoretical and (or) opera- tional inconsistencies that can result in failure to accurately recover and represent species. This failure not only obfuscates nematode taxonomy but hinders other research programs in hematology that are dependent upon a phylogenetically correct taxonomy, such as biodiversity, biogeography, cospeciation, coevolution, and adaptation. Three types of systematic errors inherent in different species concepts and their potential effects on these research programs are presented. These errors include overestimating and underestimating the number of species (type I and II error, respectively) and misrepresenting their phylogenetic relationships (type III error). For research programs in hematology that utilize recovered evolutionary history, type II and III errors are the most serious. Linnean, biological, evolutionary, and phylogenefic species concepts are evaluated based on their sensitivity to systematic error. Linnean and biologica[ species concepts are more prone to serious systematic error than evolutionary or phylogenetic concepts. As an alternative to the current paradigm, an amalgamation of evolutionary and phylogenetic species concepts is advocated, along with a set of discovery operations designed to minimize the risk of making systematic errors. Examples of these operations are applied to species and isolates of Heterorhab- ditis. Key words: adaptation, biodiversity, biogeography, coevolufion, comparative method, cospeciation, evolution, nematode, philosophy, species concepts, systematics, taxonomy. -

Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field
Attachment J Assessment of Existing Paleontologic Data Along with Field Survey Results for the Jonah Field June 12, 2007 ABSTRACT This is compilation of a technical analysis of existing paleontological data and a limited, selective paleontological field survey of the geologic bedrock formations that will be impacted on Federal lands by construction associated with energy development in the Jonah Field, Sublette County, Wyoming. The field survey was done on approximately 20% of the field, primarily where good bedrock was exposed or where there were existing, debris piles from recent construction. Some potentially rich areas were inaccessible due to biological restrictions. Heavily vegetated areas were not examined. All locality data are compiled in the separate confidential appendix D. Uinta Paleontological Associates Inc. was contracted to do this work through EnCana Oil & Gas Inc. In addition BP and Ultra Resources are partners in this project as they also have holdings in the Jonah Field. For this project, we reviewed a variety of geologic maps for the area (approximately 47 sections); none of maps have a scale better than 1:100,000. The Wyoming 1:500,000 geology map (Love and Christiansen, 1985) reveals two Eocene geologic formations with four members mapped within or near the Jonah Field (Wasatch – Alkali Creek and Main Body; Green River – Laney and Wilkins Peak members). In addition, Winterfeld’s 1997 paleontology report for the proposed Jonah Field II Project was reviewed carefully. After considerable review of the literature and museum data, it became obvious that the portion of the mapped Alkali Creek Member in the Jonah Field is probably misinterpreted. -

GREGORY MCDONALD3 1Tweet Paleo-Consulting, 9149 79th Street S., Cottage Grove, MN 55016, -email: [email protected]; 2National Park Service, Geologic Resources Division, 1201 Eye Street, NW, Washington, D.C. 20005, -email: [email protected]; 3Bureau of Land Management, Utah State Office, 440 West 200 South, Suite 500, Salt Lake City, UT 84101: -email: [email protected] Abstract—More than 4850 species, subspecies, and varieties of fossil organisms have been named from specimens found within or potentially within National Park System area boundaries as of the date of this publication. These plants, invertebrates, vertebrates, ichnotaxa, and microfossils represent a diverse collection of organisms in terms of taxonomy, geologic time, and geographic distribution. In terms of the history of American paleontology, the type specimens found within NPS-managed lands, both historically and contemporary, reflect the birth and growth of the science of paleontology in the United States, with many eminent paleontologists among the contributors. Name-bearing type specimens, whether recovered before or after the establishment of a given park, are a notable component of paleontological resources and their documentation is a critical part of the NPS strategy for their management. In this article, name-bearing type specimens of fossil taxa are documented in association with at least 71 NPS administered areas and one former monument, now abolished.
