    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.

  • The Tarsometatarsus of the Middle Eocene Loon Colymbiculus Udovichenkoi

Göhlich & Andreas Kroh (Eds) The tarsometatarsus of the Middle Eocene loon Colymbiculus udovichenkoi GERALD MAYR1, LEONID GOROBETS2 & EVGENIJ ZVONOK3 1 Senckenberg Research Institute and Natural History Museum Frankfurt, Frankfurt am Main, Germany; E-mail: [email protected] 2 Taras Shevchenko National University of Kiev, Dept. of Ecology and Environmental Protection, Kiev, Ukraine 3 Institute of Geological Sciences of NAS of Ukraine, Branch of Paleontology and Stratigraphy, Kiev, Ukraine Abstract — We describe the previously unknown tarsometatarsus of the earliest unambiguously identified loon, Colymbiculus udovichenkoi, from the Middle Eocene of the Ukraine. Except for being more elongate and apart from details of the hypotarsus morphology, the bone resembles the tarsometatarsus of the Early Miocene Colym- boides minutus. We consider the hypotarsus morphology of Colymbiculus to be plesiomorphic for Gaviiformes. Colymboides and crown group Gaviiformes are each characterized by an autapomorphic hypotarsus morphology, which precludes the former from being directly ancestral to the latter. The similarities shared by C. udovichenkoi and C. minutus, including their small size, are likely to be plesiomorphic for Gaviiformes. Although the disap- pearance of small stem group Gaviiformes may be related to the retreat of loons to cold Northern latitudes, more data are needed to firmly establish this hypothesis. We finally note that early Paleogene stem group Gaviiformes markedly differ from putative Late Cretaceous loons, whose identification needs to be verified by further fossil specimens.

The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds.

Resum El crani de Sylviornismostra una articulació craniarostral completament mòbil, amb dos còndils articulars situats sobre el rostrum, el qual s'insereix al crani en dues superfícies articulars allargades. La presència de dos procesos rostropterigoideus sobre el basisfenoide del rostrum i la forma dels palatins permet confirmar que aquest gènere pertany als Galliformes, però les característiques altament derivades del crani justifiquen el seu emplaçament a una nova família, extingida, Sylviornithidae. El crani de Syluiornis està extremadament eixamplat i dorsoventralment aplanat, mentre que el rostrum és massís, lateralment comprimit, dorsoventralment aixecat i mostra unes cristae tomiales molt fondes. El rostrum exhibeix un ornament ossi gran. La mandíbula mostra una símfisi molt allargada, les branques laterals també presenten unes cristae tomiales fondes, i la part posterior de la mandíbula és molt gruixada. Es discuteix el possible origen i l'alimentació de Syluiornis. Paraules clau: Aves, Galliformes, Extinció, Holocè, Nova Caledònia.
