  • The Largest Tropical Peat Mires in Earth History
    Geological Society of America Special Paper 370 2003 Desmoinesian coal beds of the Eastern Interior and surrounding basins: The largest tropical peat mires in Earth history Stephen F. Greb William M. Andrews Cortland F. Eble Kentucky Geological Survey, University of Kentucky, Lexington, Kentucky 40506, USA William DiMichele Smithsonian Institution, National Museum of Natural History, Washington, D.C., USA C. Blaine Cecil U.S. Geological Survey, Reston, Virginia, USA James C. Hower Center for Applied Energy Research, University of Kentucky, Lexington, Kentucky, USA ABSTRACT The Colchester, Springfield, and Herrin Coals of the Eastern Interior Basin are some of the most extensive coal beds in North America, if not the world. The Colchester covers an area of more than 100,000 km^, the Springfield covers 73,500-81,000 km^, and the Herrin spans 73,900 km^. Each has correlatives in the Western Interior Basin, such that their entire regional extent varies from 116,000 km^to 200,000 km^. Correlatives in the Appalachian Basin may indicate an even more widespread area of Desmoinesian peatland development, although possibly sUghtly younger in age. The Colchester Coal is thin, but the Springfield and Herrin Coals reach thicknesses in excess of 3 m. High ash yields, dominance of vitrinite macerals, and abundant lycopsids suggest that these Desmoinesian coals were deposited in topogenous (groundwater fed) to solige- nous (mixed-water source) mires. The only modern mire complexes that are as wide- spread are northern-latitude raised-bog mires, but Desmoinesian

  • The Barremian Heteromorph Ammonite Dissimilites from Northern Italy: Taxonomy and Evolutionary Implications
    The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxonomy and evolutionary implications ALEXANDER LUKENEDER and SUSANNE LUKENEDER Lukeneder, A. and Lukeneder, S. 2014. The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxon- omy and evolutionary implications. Acta Palaeontologica Polonica 59 (3): 663–680. A new acrioceratid ammonite, Dissimilites intermedius sp. nov., from the Barremian (Lower Cretaceous) of the Puez area (Dolomites, northern Italy) is described. Dissimilites intermedius sp. nov. is an intermediate form between D. dissimilis and D. trinodosum. The new species combines the ribbing style of D. dissimilis (bifurcating with intercalating single ribs) with the tuberculation style of D. trinodosum (trituberculation on entire shell). The shallow-helical spire, entirely comprising single ribs intercalated by trituberculated main ribs, is similar to the one of the assumed ancestor Acrioceras, whereas the increasing curvation of the younger forms resembles similar patterns observed in the descendant Toxoc- eratoides. These characters support the hypothesis of a direct evolutionary lineage from Acrioceras via Dissimilites to Toxoceratoides. D. intermedius sp. nov. ranges from the upper Lower Barremian (Moutoniceras moutonianum Zone) to the lower Upper Barremian (Toxancyloceras vandenheckii Zone). The new species allows to better understand the evolu- tion of the genus Dissimilites. The genus appears within the Nicklesia pulchella Zone represented by D. duboise, which most likely evolved into D. dissimilis. In the Kotetishvilia compressissima Zone, two morphological forms developed: smaller forms very similar to Acrioceras and forms with very long shaft and juvenile spire like in D. intermedius sp. nov. The latter most likely gave rise to D. subalternatus and D. trinodosum in the M.

  • 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.

  • A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
    A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere.
