Abstract

Paleogeography and paleoclimates are central aspects of Project CRER that relate to all the other working groups. The initial, short-term, pilot project in paleogeograph is to prepare a map of landmasses, seas, highlands, and lowlands for the Ultra-thermal period, the latest Cenomanian to earliest Turonian. A longer-term goal is to prepare a second paleogeographic map for the cool period of relatively low sea level, early Aptian, that preceeded the Ultra-thermal.. In paleoclimatology, the overall goal is to supplement existing information on paleclimates for two intervals of the Cretaceous. Initially, the focus will be to characterize the global climate of the Ultra-thermal as an ancient analogue for a future greenhouse state of Planet Earth. The longer-term goal is to compile data on paleoclimate for the other and quite different state of the Cretaceous, the period from late Albian to the end of the Turonian. The climatic indicators that will be assembled include stabe isotope ratios, patterns of vegetation, chalks, ice-rafted sediments, bauxites, and latentes.
