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. -
Mammalian Faunal Succession in the Cretaceous of the Kyzylkum Desert
Journal of Mammalian Evolution, Vol. 12, Nos. 1/2,C 2005)June 2005 ( DOI: 10.1007/s10914-005-4867-3 A number of typographical errors were introduced during copyediting. All that were found were corrected in this version. Mammalian Faunal Succession in the Cretaceous of the Kyzylkum Desert J. David Archibald1,3 and Alexander O. Averian2 ov Both metatherians and eutherians are known from the Early Cretaceous (Barremian, 125 mya; million years ago) of China, while eutherian-dominated mammalian faunas appeared in Asia at least by the earliest Late Cretaceous (Cenomanian, 95 mya). The approximately 99–93 my old (Cenomanian) Sheikhdzheili l.f. from western Uzbekistan is a small sample of only eutherians, including three zhelestids and a possible zalambdalestoid. The much better-known 90 my old (Turonian) Bissekty l.f. at Dzharakuduk iin central Uzbekistan includes 15 named and un- named species, based on ongoing analyses. Of these, 12 are eutherians represented by at least the three groups—asioryctitheres, zalambdalestids, and zhelestids—plus an eutherian of uncertain position—Paranyctoides. Zalambdalestids and zhelestids have been argued to be related to the origin of the placental gliriforms (Euarchontoglires) and ferungulates (Laurasiatheria), respec- tively. Although there are four previously recognized metatherians, we believe three are referable to the deltatheroid Sulestes karakshi and the fourth, Sailestes quadrans, may belong to Paranyc- toides. There is one multituberculate and one symmetrodont in the Bissekty l.f. While comparably aged (Turonian) localities in North America have somewhat similar non-therians, they have more metatherians and no eutherians. The next younger localities (early Campanian, ∼80 mya) in North America have both a zhelestid and Paranyctoides, suggesting dispersal of eutherians from Asia. -

Aptian–Albian) of Texas and Oklahoma
Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma BRIAN M. DAVIS and RICHARD L. CIFELLI Davis, B.M. and Cifelli, R.L. 2011. Reappraisal of the tribosphenidan mammals from the Trinity Group (Aptian–Albian) of Texas and Oklahoma. Acta Palaeontologica Polonica 56 (3): 441–462. The Trinity therians have long been the focus of attempts to reconstruct the evolutionary history of higher mammals, es− pecially in the context of the development of tribospheny. In this paper, we update the taxonomy of the tribosphenidan taxa known from the Trinity Group and establish with more confidence the premolar/molar count in each. Many isolated specimens can be referred to a specific tooth locus. Additional diversity is revealed within the Deltatheroida, with the de− scription of an additional species of Oklatheridium; Pappotherium is here considered a likely metatherian based on the in− ferred presence of four molars, while Holoclemensia is a basal eutherian (the opposite of some traditional interpretations). The remainder of the genera, Kermackia and Slaughteria, cannot be allied with either of the living groups of tribo− sphenidan mammals using the available data. We identify strong morphological diversity within this assemblage of stem taxa, including modifications to the traditional tribosphenic occlusal pattern in Kermackia. Mammalian evolution at the base of the tribosphenidan radiation was complex, and this underscores the need for caution when interpreting the mor− phology and relationships of taxa known by incomplete material. Key words: Tribosphenida, Metatheria, Eutheria, Deltatheroida, Trinity Group, Early Cretaceous. Brian M. Davis [[email protected]] and Richard L.

AMERICAN MUSEUM NOVITATES Published by Number 330 THz AuERicAN MusEUM oF NAITURAL HISTORY October 30, 1928 New York City 56.9,33 (117:51.7) AFFINITIES OF THE MONGOLIAN CRETACEOUS INSECTIVORES' BY GEORGE GAYLORD SIMPSON The unique series of Mesozoic mammal remains found by the Third Asiatic Expedition in Mongolia has now been completely de- scribed in a series of three papers.2 The affinities of the one known multituberculate, Djadochtatherium matthewi, were as thoroughly discussed as the material warrants in the first paper, and no additional remarks seem necessary. The relationships of the more important insectivores, however, were only briefly discussed in the second paper and a review of the evidence, especially including the important new details given in the third paper, suggests some modification and amplification of the views already presented. Not only are these mammal remains by far the most complete ever discovered in the Mesozoic, but they also occupy a very strategic position in time and in space which makes close scrutiny of their relationships essential. In time they occur in the Cretaceous, when, according to theories formed before their discovery and based largely on early Tertiary mammals, the differentiation of the placental orders should be in progress and not yet far advanced. In space they occur in Central Asia in or near the region which a number of students, especially Osborn and Matthew, have considered as an important center of radiation and probably the very one whence came the groups of mammals which appear to have entered North America and Europe suddenly at the beginning of the Tertiary and which must have been undergoing an important deployment during upper Cretaceous time. -
