To balance land values exchanged under that act, the coal estates on several tracts of federal coal underlying the Manti- LaSal National Forest (MLNF) were conveyed to the State of Utah School and Institutional Trust Lands Administration (SITLA). This conveyance is temporal and the ownership of the coal will revert back to the federal government once a specific tonnage is produced or a specified royalty value is collected. On the conveyed coal estates, SITLA has sole authority to lease the coal. Under the Surface Mine Control and Reclamation Act of 1977 and Utah Coal Rules, Forest Service must consent to the mine plan prior to mine development and can impose requirements for the protection of non-coal resources. The Forest Service decisions, as federal actions, are subject to the requirements of the National Environmental Policy Act of 1969 (NEPA), requiring environmental analysis and appropriate NEPA documents. The U.S. Department of Interior, Bureau of Land Management (BLM) is the leasing authority on the remaining federal coal estates within the Muddy Creek tract on National Forest System land. Under the Mineral Leasing Act of 1920, as amended by the Federal Coal Leasing Amendments Act of 1975, leases can only be issued by the BLM with consent from the Forest Service with conditions for protection of non-mineral resources. As federal actions subject to NEPA, both the BLM leasing decisions and the Forest Service consent decisions must be based on an environmental analysis and appropriate NEPA document. This resources technical report presents the results of analysis of the geology and paleontology of the Greens Hollow Federal Coal Lease Tract (Greens Hollow tract) conducted by Erathem-Vanir Geological Consultants (EVG, Pocatello, ID). EVG’s review supplements previous work in the area for the Muddy Tract (Cirrus 2004). Work for the Muddy Tract included a search of geologic and paleontological literature and maps, and discussions with Forest Service experts (McClelland 2003 and Robison 2003) with local experience. This report supplemented a confidential paleontology inventory of the Manti-La Sal National Forest conducted by the Forest Service (DeFreest 2000) and incorporated information derived from study of the same rock units as exposed in the project area conducted by EVG for the Aspen Pipeline in 1999 and along US Highway 6 between Interstate 15 and Interstate 80 in 2003 for SWCA, Inc in Salt Lake City. This technical report supplements this earlier work and will form the basis for an analysis of impacts to paleontological resources in the project area in the subsequent Environmental Impact Statement (EIS) planned for the Greens Hollow tract. 1 Paleontology Technical Report 2013 Greens Hollow Coal Lease Tract 1.2 STATEMENT OF THE ISSUES WITH EVALUATION CRITERIA Issue: Mining and subsequent subsidence could impact unidentified paleontological resources. Evaluation Criteria: Expected prehistoric sites and effects to them. Number of significant sites impacted. Potential impact on paleontological resources. Mining and associated subsidence could cause surface collapse or other disturbance that could adversely impact paleontological resources. Construction of reasonably foreseeable surface facilities for the mine could also adversely impact paleontological resources. BLM and USDA Forest Service policy recognizes that paleontological resources found on public lands constitute a fragile and nonrenewable scientific record of the history of life on Earth and so represent an important and critical component of America’s natural heritage. Once damaged, destroyed, or improperly collected, their scientific and educational value may be greatly reduced or lost forever. In addition to their scientific, educational and recreational values, paleontological resources can be used to inform land managers about interrelationships between the biological and geological components of ecosystems over long periods of time. The BLM and Forest Service manage paleontological resources for these values, and mitigates adverse impacts to them. To accomplish this goal, paleontological

    Diapsid Phylogeny and the Origin and Early Evolution of Squamates by Tiago Rodrigues Simões A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in SYSTEMATICS AND EVOLUTION Department of Biological Sciences University of Alberta © Tiago Rodrigues Simões, 2018 ABSTRACT Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions remain to be answered regarding the early evolution and origin of this major clade of tetrapods. Such long-standing issues include identifying the oldest fossil squamate, when exactly did squamates originate, and why morphological and molecular analyses of squamate evolution have strong disagreements on fundamental aspects of the squamate tree of life. Additionally, despite much debate, there is no existing consensus over the composition of the Lepidosauromorpha (the clade that includes squamates and their sister taxon, the Rhynchocephalia), making the squamate origin problem part of a broader and more complex reptile phylogeny issue. In this thesis, I provide a series of taxonomic, phylogenetic, biogeographic and morpho-functional contributions to shed light on these problems. I describe a new taxon that overwhelms previous hypothesis of iguanian biogeography and evolution in Gondwana (Gueragama sulamericana). I re-describe and assess the functional morphology of some of the oldest known articulated lizards in the world (Eichstaettisaurus schroederi and Ardeosaurus digitatellus), providing clues to the ancestry of geckoes, and the early evolution of their scansorial behaviour.

NOVEMBER 1953 GEOLOGY OF THE WEST-CENTRAL PART OF THE GUNNISON PLATEAU, UTAH BY CLYDE T. HARDY AND HOWARD D. ZELLER ABSTRACT A detailed study of the west-central part of the Gunnison Plateau, Utah, has disclosed stratigraphic and structural relations important in the geological history of central Utah. The area mapped includes the east- ern half of the Axtell No. 2 quadrangle, Manti area (U. S. Dept, of Agriculture, Soil Conservation Service). The bedrock ranges in age from the Arapien shale (Upper Jurassic) to the Green River formation (Eo- cene). The North Horn formation (Cretaceous-Tertiary), the Flagstaff limestone (Paleocene-Eocene), and the Green River formation (Eocene) successively overlap the Arapien shale and the Indianola group in the northern part of the area. In the southern part of the area, the North Horn formation and the Flagstaff limestone successively overlap the Price River conglomerate with angular discordance. The latter relation establishes a post-Price River and pre-North Horn orogenic movement in central Utah. A conspicuous west-dipping monocline, broken by many high-angle faults and a graben, extends along most of the western margin of the area. This structure is similar to the monocline and graben in the Wasatch Plateau to the east.
