The first is a general introduction and is not intended for publication. It serves to provide background information and context for the reader unfamiliar with the Cretaceous period. Chapters 2 and 3 are intended for independent publication. Chapter 2 provides an overview of the Mussentuchit fauna from an ecological perspective and examines the role of taphonomy in evaluating ecological patterns. Chapter 3 demonstrates sampling completeness. Chapters 4 through 6 are intended for publication as a set, in collaboration with R. Cifelli. Some redundancy between chapters necessarily follows. Chapter 4 demonstrates similarities and differences in faunal composition among sites. Chapter 5 examines taphonomic similarity among sites, and Chapter 6 examines faunal distributions from an ecological perspective. Format style in all chapters follows publication guidelines for submission to Paleobiology. IV ACKNOWLEDGMENTS This dissertation was very much a community effort and drew from the strengths and knowledge of many people. In particular I thank my committee members, Richard Cifelli, Nick Czaplewski, Gary Schnell, Mike Kaspari, and Bruce Hoagland, each of whom contributed significant guidance, support, and knowledge in their respective fields. Every last one of them made time for me when I showed up at their doorway. This study is based on data and specimens collected over a 10 year period by R. Cifelli and crews from the Sam Noble Oklahoma Museum of Natural History at an enormous cost in time, energy, and money. R. Cifelli provided me with access to specimens, databases, field notes, maps, unpublished manuscripts, and research materials and facilities. He was greatly instrumental in helping me get support in the manner of grants and scholarships for this work. In addition, he personally took me to all the microsites analyzed in this paper, taking care of permits, paperwork, and even arranging for the assistance of the Utah state geologist Needless to say, this dissertation simply never would have happened without him. Jim Kirkland spent two days in the Utah desert patiently sharing his geological knowledge with a novice (me). Rick Lupia came to the museum my last year in residence, and provided a great deal of assistance with (and enthusiasm about) paleoecologicai statistics. Coral McCalister drafted figures 3 (Chapter I) and I (Chapters 2 and 3), saving me a lot of headache and doing a better job than I could. My fellow graduate students, Cindy Gordon, Randy Nydam, Kent Smith, Julian Hilliard, and Matt Wedel, provided invaluable discussion and moral support Arthur Harris, my former professor, has always very quietly provided encouragement in my goals and confidence in my abilities. Funding for much of this work was provided through research and travel grants from the Hniversitj' of Oklahoma Graduate Student Senate and the University of Oklahoma Department of Zoology, as well as scholarships from the Alfred and Rose Miniaci Scholarship Fund (Dinamation International Society) and Blanche and Francis Adams Scholarship Fund. National Science Foundation grants (BSR 8906992, DEB 9401094, and DEB 9870173) and National Geographic grants (4761-91 and 5021-92) to R. Cifelli funded all the work to generate the data used in the first place. Finally, I would like to thank my family. My parents prodded me to go to college and encouraged my interest in nature. My husband has been my partner, advocate, and friend. He has tolerated all the demands and complications that have arisen along the way with good humor. Lastly, I thank my son, Raymond, who sacrificed time with his mom this past year with a maturity, thoughtfulness, and sense of humor way beyond his years.

Although numerous aspects of knee morphology are ancient and conserved among most tetrapods, the evolutionary occurrence of an ossified patella is highly variable. Among extant (crown clade) groups it is found in most birds, most lizards, the monotreme mammals and almost all placental mammals, but it is absent in most marsupial mammals as well as many reptiles. Here we integrate data from the literature and first-hand studies of fossil and recent skeletal remains to reconstruct the evolution of the mammalian patella. We infer that bony patellae most likely evolved between four to six times in crown group Mammalia: in monotremes, in the extinct multituberculates, in one or more stem-mammal genera outside of therian or eutherian mammals, and up to three times in therian mammals.

Received: 15 December 2013 / Accepted: 18 December 2014 / Available online: 25 March 2015 Abstract In 2011 the partial skeleton of a goniopholidid crocodylomorph was recovered in the ENDESA coal mine Mina Corta Barrabasa (Escu- cha Formation, lower Albian), located in the municipality of Andorra (Teruel, Spain). This new goniopholidid material is represented by abundant postcranial and fragmentary cranial bones. The study of these remains coincides with a recent description in 2013 of at least two new species of goniopholidids in the palaeontological site of Mina Santa María in Ariño (Teruel), also in the Escucha Formation. These species are Anteophthalmosuchus escuchae, Hulkepholis plotos and an undetermined goniopholidid, AR-1-3422. In the present paper, we describe the postcranial and cranial bones of the goniopholidid from Mina Corta Barrabasa and compare it with the species from Mina Santa María.

  • 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.

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

  • 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.
