متن کاملMammal extinctions, body size, and paleotemperature.
There is a general inverse relationship between the natural logarithm of tooth area (a body size indicator) of some fossil mammals and paleotemperature during approximately 2.9 million years of the early Eocene in the Bighorn Basin of northwest Wyoming. When mean temperatures became warmer, tooth areas tended to become smaller. During colder times, larger species predominated; these generally b...
متن کاملOxygen Isotope Paleotemperature Determinations of Australian Cainozoic Fossils.
Fossil marine shells collected in southern Victoria within half a degree of latitude of 38(1/2) degrees S have been analyzed for O(18)/O(16) by mass spectroscopy, and their paleotemperatures have been determined. For the genera Chlamys, Ostrea, and Glycymeris the temperature rises from early to mid-Tertiary, then falls again to the present.
متن کاملPaleotemperature reconstruction in tropical Africa using fossil Chironomidae (Insecta: Diptera)
Fossil assemblages of chironomid larvae (non-biting midges) preserved in lake sediments are well-established paleothermometers in north-temperate and boreal regions, but their potential for temperature reconstruction in tropical regions has never before been assessed. In this study, we surveyed subfossil chironomid assemblages in the surface sediments of 65 lakes and permanent pools in southwes...
