description Gerta Keller Overview
Gerta Keller is a micropaleontologist and professor at Princeton University who specializes in the study of foraminifera to understand mass extinctions. Born in Switzerland, her research focuses heavily on the Cretaceous-Paleogene (K-Pg) boundary, where she challenges the widely accepted theory that a single asteroid impact was solely responsible for the extinction of the dinosaurs. Instead, she emphasizes the role of the Deccan Traps volcanic eruptions in causing gradual environmental collapse. Her work is intended for the scientific community and researchers of Earth's biological history.
help Gerta Keller FAQ
What does Gerta Keller study?
Gerta Keller is a micropaleontologist who studies foraminifera and mass extinctions. Her work focuses especially on evidence preserved at the Cretaceous-Paleogene boundary.
Where did Gerta Keller work as a professor?
Keller served as a professor at Princeton University. She was born in Switzerland and built her research career around paleontology and extinction events.
What is Gerta Keller's view of the K-Pg extinction?
Keller has challenged the view that the Chicxulub asteroid impact alone explains the extinction at the Cretaceous-Paleogene boundary. She has argued for a stronger role for volcanic activity and climate effects, based on her interpretation of fossil and sediment evidence.
Why are foraminifera useful in Keller's research?
Foraminifera are tiny organisms with shells that can be preserved in marine sediments. Their distribution and chemistry help researchers reconstruct past environments around events such as the K-Pg extinction.
