Information
Section research and collecting continues to investigate late
Devonian and Carboniferous climate change and its implication
to biotic evolution and extinction. During this episode of global
climate change from the late Devonian through the late Pennsylvanian
or 65 million years of time, global climatic cooling and warming
had a profound affect on the Earth’s paleoenvironments,
sea level, extinctions and evolution. Preliminary evidence (invertebrate
fossils) collected from the Carboniferous reefs of the Bridger
Range of Montana, New Mexico, and Oklahoma, suggests an apparent
biotic recovery from the marine extinctions of the Late Devonian
Ice House climate.
Research on the Geology of the classic Carnegie Museum Dinosaur
Quarries in Sheep Creek, Wyoming and the Earl Douglas (Dinosaur
National Monument) Jensen, Utah continues.
Closer to home, the investigation of the rocks of the Pittsburgh
region for evidence on late Pennsylvanian climate change continues
and how it might affect tetrapod (vertebrate) evolution during
the Carboniferous.
