Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana

Non-dinosaurian Lower Vertebrates Across the Cretaceous-Tertiary Boundary in Northeastern Montana PDF Author: Laurie J. Bryant
Publisher: Univ of California Press

Pages : 128

Book Description
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.
