Down to Earth With: Paleontologist Gerta Keller


The mass extinction that did in the dinosaurs is one of the best-known events in geology. It’s also one of the most contentious. Princeton University paleontologist Gerta Keller has long argued that volcanism was to blame, not the famous asteroid impact.

EARTH sat down with Keller to talk about her upbringing in the Alps, her experience as an unwelcome critic of a mainstream scientific idea, and her long quest to understand the role of flood basalts.

Keller and others argue that an intense episode of volcanic activity in what is now India caused the extinction event that wiped out all non-avian dinosaurs, shown here in an artist’s rendition. (Credit: National Science Foundation, Zina Deretsky)
