Book Synopsis The Bug Creek Problem and the Cretaceous-Tertiary Transition at McGuire Creek, Montana by : Donald L. Lofgren
Download or read book The Bug Creek Problem and the Cretaceous-Tertiary Transition at McGuire Creek, Montana written by Donald L. Lofgren and published by Univ of California Press. This book was released on 1995-08-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana by : Laurie J. Bryant
Download or read book Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana written by Laurie J. Bryant and published by Univ of California Press. This book was released on 1989-01-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.

This book was released on 1988 with total page 830 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of pollen and spores across the Cretaceous-Tertiary boundary in Garfield and McCone Counties, Montana was studied to determine whether the pattern of change in vegetation was compatible with a hypothesis of extraterrestrial impact as an agent of extinction. Fifteen sections in the (Cretaceous) Hell Creek and (Tertiary) Tullock Formations, including six boundary sections containing unusually high concentrations of iridium, were examined. Of 291 species of pollen and spores, 45 species of spores, 20 species of gymnosperms and about 225 species of angiosperms were recognized and described in Part II; these constitute the database upon which the statistical analysis in Part I rests
