Canada Dedication To my family, friends, and colleges Abstract Permineralized fossil remains of ?dinoflagellates, mosses, ferns, gymnosperms and angiosperms have been found in calcium carbonate concretions from the Eden Main fossil localities, British Columbia, Canada. Fossils come from the Upper Cretaceous Comox Formation of the Nanaimo Group and have been dated as Coniacian in age. A survey of the fossil floral assemblage has revealed morphotaxa of eleven seedless vascular plants from stipes and rhizomes. A new species of Paralygodium, a schizaeaceous fern, is described from fertile pinnules. Seven gymnosperm organs are known including a cycadophyte stem, cupressaceous leaves, twigs and cones, and pinaceous leaves and a pollen cone. Twenty-five angiosperm morphotaxa are also currently recognized based on flowers, inflorescences, fruits, and wood. The presence of several taxa with extant relatives that are currently found in the tropics, and abundant fusain indicates that western North America was warm during the Coniacian, probably experienced wet and dry seasons. Acknowledgements I wish to thank my supervisor Dr. Ruth Stockey (University of Alberta) for her guidance and hospitality over the last few years, none of this would have been possible without her assistance. I also wish to thank my committee, Dr. Randolph Currah and Dr. Jocelyn Hall and Alexander Wolfe (University of Alberta) for their advice and assistance as I've run into questions during my research. I'd also like to thank Dr. Gar Rothwell (Ohio Universaity) for sparking my interest in the field of paleobotany with his inspiring teaching, and for allowing me to work in his lab as an undergraduate student. To my lab mates past and present, Dr. Genaro Rodrigo Hernandez Castillo, Dr. Stefan Little, Dr. Selena Smith, Dr. Randal Mindell, AJ Harris, Jen Gemmel, Ashley Klymiuk, Kirstin Brink and Brian Rankin. I would also like to acknowledge Dr. Heather Sanders, Marie Davey, Marcie Plishka, and Dr. Thomas Simonsen, for their scholarly conversations and friendship. Also the following people deserve acknowledgement for their help over the last few years, Dr. Dirk Meckert and Rick Ross (Courtenay, BC) for help in the field, Dr. Peter Mustard (Simon Fraser University) for discussion on the geology of Eden Main as well as allowing me to modify figures for this thesis; Dr. Jim Haggart (Geological Survey of Canada) for information on the geology of Eden Main, and George Braybrook (University of Alberta) for his superb SEM assistance. I would also like to thank the following people for helpful discussion, Dr. A.R. Sweet (Geological Survey of Canada) Dr. Harufumi Nishida (Chuo University), Dr. Estella Leopold (University of Washington), Dr. Vera Pspelova (University of Victoria), Dr. Eva Koppelhus (University of Alberta), Dr. Catherine LaFarge (University of Alberta), Nathan Jud (Ohio University), Dr. Steven Manchester (University of Florida), Dr. Elsa Marie Friis (Swedish Museum of Natural History), Dr. Jim Doyle (University of California, Davis), Dr. John T. Mickel (New York Botanical Garden), Dr. Thomas N. Taylor (University of Kansas), Dr. Peter Crane (University of Chicago), Dr. Bruce Tiffhey (University of California, Santa Barbara) and Dr. Alfred Traverse (Pennsylvania State University). Last but not least, I would like to thank my family. My mom, Brenda and dad, Jim Karafit for their endless support and to my brother Joe. Thanks is also due to Uncle John for sparking my interest in fossils by sharing his knowledge about rocks and fossils with me as a child. To Emilie Karafit and Margie Wenning, my grandmothers, for their - support and worry about my well being. This thesis was supported in part by NSERC grant A-6908 to RAS.
