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
