| 1. |  | Title: The Bug Creek problem and the Cretaceous-Tertiary transition at McGuire Creek, Montana  Author: Lofgren, Donald L 1950- Published: University of California Press, 1995 Subjects: Science | Paleontology Publisher's Description: Bug Creek assemblages from Montana, transitional in composition between typical Cretaceous and Paleocene vertebrate faunas, are critical to K-T extinction debates because they have been used to support both gradual and catastrophic K-T extinction scenarios. Geological and palynological data from McGuire Creek indicate that Bug Creek assemblages are Paleocene and restricted to channel fills entrenched into older sediments, suggesting that the Cretaceous component of the assemblage was reworked. Thus, the author concludes, "Paleocene dinosaurs" are an illusion and the K-T survival rate of mammals is low because the presence of Cretaceous mammals in Bug Creek assemblages is also the result of reworking.

| 3. |  | Title: Mesozoic birds: above the heads of dinosaurs Author: Chiappe, Luis M Published: University of California Press, 2002 Subjects: Organismal Biology | Ornithology | Paleontology | Evolution Publisher's Description: Our knowledge of the origin and early evolution of birds has exploded in the past ten to fifteen years. In the 1990s alone, scientists became aware of approximately three times more species of early birds than were previously known, marking the first 85 million years of avian development as a period of remarkable species diversity. Assembling work by an international group of renowned scientists, Mesozoic Birds: Above the Heads of Dinosaurs is the most authoritative and up-to-date source on early avian evolution currently available. This unique resource provides a comprehensive examination of the known fossil record and is also an unparalleled guide to the fast-paced developments in current research. Mesozoic Birds: Above the Heads of Dinosaurs covers a wide range of topics, including discussions of avian origins, the fossil record of feathers and footprints, bone histology, and locomotor evolution. Controversial taxa such as Protoavis, Caudipteryx, and Mononykus receive special treatment. But the heart of the volume presents the anatomy, relationships, and paleobiology of the undisputed Mesozoic aviary. Some of the book's most exciting features are the new definitive descriptions and illustrations of taxa that previously have received only brief notice, such as the alvarezsaurid Shuvuuia; the enantiornithines Sinornis; Eoalulavis, Vorona, and Patagopteryx; and the hesperornithiform Enaliornis. The origin of birds and their relationship to dinosaurs continue to be hotly debated among paleontologists, ornithologists, and evolutionary biologists. This cutting-edge reference will become an essential resource for those interested in this debate and in the many other fascinating topics relating to the evolution of the earliest known birds.

| 4. |  | Title: Life's origin: the beginnings of biological evolution Author: Schopf, J. William 1941- Published: University of California Press, 2002 Subjects: Organismal Biology | Paleontology | Astronomy | Evolution | Earth Sciences | Physical Sciences Publisher's Description: Always a controversial and compelling topic, the origin of life on Earth was considered taboo as an area of inquiry for science as recently as the 1950s. Since then, however, scientists working in this area have made remarkable progress, and an overall picture of how life emerged is coming more clearly into focus. We now know, for example, that the story of life's origin begins not on Earth, but in the interiors of distant stars. This book brings a summary of current research and ideas on life's origin to a wide audience. The contributors, all of whom received the Oparin/Urey Gold Medal of the International Society for the Study of the Origin of Life, are luminaries in the fields of chemistry, paleobiology, and astrobiology, and in these chapters they discuss their life's work: understanding the what, when, and how of the early evolution of life on Earth. Presented in nontechnical language and including a useful glossary of scientific terms, Life's Origin gives a state-of-the-art encapsulation of the fascinating work now being done by scientists as they begin to characterize life as a natural outcome of the evolution of cosmic matter.

| 5. |  | Title: On her own terms: Annie Montague Alexander and the rise of science in the American West Author: Stein, Barbara R 1955- Published: University of California Press, 2001 Subjects: Autobiographies and Biographies | History of Science | Paleontology | California and the West | Women's Studies Publisher's Description: At a time when women could not vote and very few were involved in the world outside the home, Annie Montague Alexander (1867-1950) was an intrepid explorer, amateur naturalist, skilled markswoman, philanthropist, farmer, and founder and patron of two natural history museums at the University of California, Berkeley. Barbara R. Stein presents a luminous portrait of this remarkable woman, a pioneer who helped shape the world of science in California, yet whose name has been little known until now. Alexander's father founded a Hawaiian sugar empire, and his great wealth afforded his adventurous daughter the opportunity to pursue her many interests. Stein portrays Alexander as a complex, intelligent, woman who--despite her frail appearance--was determined to achieve something with her life. Along with Louise Kellogg, her partner of forty years, Alexander collected thousands of animal, plant, and fossil specimens throughout western North America. Their collections serve as an invaluable record of the flora and fauna that were beginning to disappear as the West succumbed to spiraling population growth, urbanization, and agricultural development. Today at least seventeen taxa are named for Alexander, and several others honor Kellogg, who continued to make field trips after Alexander's death. Alexander's dealings with scientists and her encouragement--and funding--of women to do field research earned her much admiration, even from those with whom she clashed. Stein's extensive use of archival material, including excerpts from correspondence and diaries, allows us to see Annie Alexander as a keen observer of human nature who loved women and believed in their capabilities. Her legacy endures in the fields of zoology and paleontology and also in the lives of women who seek to follow their own star to the fullest degree possible. [brief] Similar Items |
