Mills A Thesis Submitted to the Graduate Faculty of St. Cloud State University in Partial Fulfillment of the Requirements for the Degree of Master of Science in Functional Morphology October, 2019 Thesis Committee: Matthew Tornow, Chairperson Mark Muñiz Bill Cook Tafline Arbor 2 Abstract Toward the end of the Middle Eocene (40-37mya), the environment started to decline on a global scale. It was becoming more arid, the tropical forests were disappearing from the northern latitudes, and there was an increase in seasonality. Research of the Chadronian (37- 33.7mya) in the Great Plains region of North America has documented the persistence of several mammalian taxa (e.g. primates) that are extinct in other parts of North America. -
The Impact of Locomotion on the Brain Evolution of Squirrels and Close Relatives ✉ Ornella C
ARTICLE https://doi.org/10.1038/s42003-021-01887-8 OPEN The impact of locomotion on the brain evolution of squirrels and close relatives ✉ Ornella C. Bertrand 1 , Hans P. Püschel 1, Julia A. Schwab 1, Mary T. Silcox 2 & Stephen L. Brusatte1 How do brain size and proportions relate to ecology and evolutionary history? Here, we use virtual endocasts from 38 extinct and extant rodent species spanning 50+ million years of evolution to assess the impact of locomotion, body mass, and phylogeny on the size of the brain, olfactory bulbs, petrosal lobules, and neocortex. We find that body mass and phylogeny are highly correlated with relative brain and brain component size, and that locomotion strongly influences brain, petrosal lobule, and neocortical sizes. Notably, species living in 1234567890():,; trees have greater relative overall brain, petrosal lobule, and neocortical sizes compared to other locomotor categories, especially fossorial taxa. Across millions of years of Eocene- Recent environmental change, arboreality played a major role in the early evolution of squirrels and closely related aplodontiids, promoting the expansion of the neocortex and petrosal lobules. Fossoriality in aplodontiids had an opposing effect by reducing the need for large brains. 1 School of GeoSciences, University of Edinburgh, Grant Institute, Edinburgh, Scotland, UK. 2 Department of Anthropology, University of Toronto Scarborough, ✉ Toronto, ON, Canada. email: [email protected] COMMUNICATIONS BIOLOGY | (2021) 4:460 | https://doi.org/10.1038/s42003-021-01887-8 | www.nature.com/commsbio 1 ARTICLE COMMUNICATIONS BIOLOGY | https://doi.org/10.1038/s42003-021-01887-8 hat ecological and evolutionary factors affect brain size striking differences between living sciurids and aplodontiids raise in mammals?

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. -

Descriptive and Comparative Osteology of the Oldest Fossil Squirrel, Protosciurus (Rodentia: Sciuridae)
Descriptive and Comparative Osteology of the Oldest Fossil Squirrel, Protosciurus (Rodentia: Sciuridae) ;RT J. EMRY I f 4H and RICHARD W. THORINGTON, JR. <%, ^ ONIAN CONTRIBUTIONS TO PALEOBIOLOGY • NUMBER 47 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropo/ogy Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -

Little published data on the geographical distribution of fossil Bothriembryon exists. In this study, fossil and modern data of Bothriembryon from nine Australian museums and institutes were mapped for the first time. The fossilBothriembryon collection in the Western Australian Museum was curated to current taxonomy. Using this data set, the geological age of fossil and extant species was documented. Twenty two extant Bothriembryon species were identified in the fossil collection, with 15 of these species having a published fossil record for the first time. Several fossil and extant species had range extensions. The geological age span of Bothriembryon was determined as a minimum of Late Oligocene to recent, with extant endemic Western Australian Bothriembryon species determined as younger, traced to Pleistocene age. Extant Bothriembryon species from the Nullarbor region were older, dated Late Pliocene to Early Pleistocene. -

The opportunities are many, ranging from the relatively rapid acquisition of data to the unprecedented ability to integrate critically important fossil taxa. The challenges consist of navigating the logistical barriers that often separate a researcher from high-quality data and minimizing the amount of non- biological variation expressed in endocasts – variation that may confound meaningful and synthetic results.
